How I Grew My Business Organically Using WhatsApp API : A Journey with Botbuz.

Not too long ago, I found myself in a familiar spot that many small business owners know well—trying to balance growth with tight marketing budgets. Paid ads were draining my resources, and I wanted a more sustainable, organic way to connect with my audience. It was during this search that I stumbled across a game-changing solution: WhatsApp API. Specifically, I found myself using Botbuz WhatsApp API Services, which transformed the way I approached marketing.

This is the story of how I grew my business organically through WhatsApp API, without the need for a huge advertising budget or complex marketing strategies. And trust me, if I could do it, so can you.

The Quest for Organic Growth

Before discovering the power of WhatsApp API, I was frustrated with traditional digital marketing methods. I had tried it all: Facebook ads, Google ads, Instagram promotions—yet I found myself constantly spending without seeing the engagement or conversion I wanted.

Then, I started thinking about my own behaviour as a consumer. I rarely clicked on paid ads but was much more responsive when businesses reached out to me directly on platforms I was already using. That’s when the lightbulb went off. Why not shift my focus to more direct, personal communication through a platform that nearly everyone uses—WhatsApp ?

After doing some research, I found out that businesses could use WhatsApp for more than just manual customer support. Enter Botbuz WhatsApp API Services—a tool that allows businesses like mine to automate and manage customer interactions while keeping everything personalized and real-time.

Why WhatsApp API ?

You might wonder, why not just use regular WhatsApp for business? Why go the API route? The truth is, while WhatsApp Business is great for small-scale operations, its features are limited when it comes to scalability and automation. On the other hand, WhatsApp API—especially when paired with Botbuz WhatsApp API Services—provides powerful tools that allow for mass communication while keeping everything highly personalized.

Here’s why I chose the API route :

Scalability : WhatsApp API lets you manage hundreds, even thousands, of conversations seamlessly. Instead of manually responding to every customer, I was able to set up automated responses to common queries, which freed up my time.

Automation: Thanks to Botbuz, I could schedule messages, send automated replies, and even set up interactive buttons and menus for my customers. Imagine someone asking for a product price, and instead of typing a response, an automated menu pops up allowing them to navigate through options—instant customer satisfaction!

Personalization : Even though the messages were automated, they felt personalized. Botbuz WhatsApp API Services allowed me to use customer names, preferences, and past interactions to tailor my messages. This made my customers feel like they were getting individualized attention.

Engagement : WhatsApp has a higher open rate compared to email or other messaging platforms. By using WhatsApp API, I ensured that my messages weren’t lost in the spam folder or overlooked in a crowded inbox.

Setting Up Botbuz WhatsApp API : The Game Changer

The setup process with Botbuz WhatsApp API Services was surprisingly straightforward. The team at Botbuz guided me through integrating the API with my existing CRM, and within a few days, I was up and running.

I started small—automating a few frequently asked questions like "What are your business hours ?" and "Do you have any promotions ?" Over time, as I saw the power of automated interactions, I expanded the use of the API to include order confirmations, shipping updates, and feedback requests.

One of the most impactful features was broadcast messaging, which allowed me to send personalized updates to multiple customers at once without losing that one-on-one conversational feel. My audience began responding more quickly, and engagement rates skyrocketed.

Organic Marketing Through WhatsApp API

With the basic setup complete, I shifted my focus to crafting an organic marketing strategy that would leverage the unique advantages of WhatsApp API.

1. Building an Engaged Audience

The first step was growing my contact list. I embedded a WhatsApp click-to-chat link on my website, in emails, and across social media platforms. Since WhatsApp is already a familiar and trusted platform for most people, I found that customers were more willing to reach out to me there than through email or phone.

Additionally, I used incentives like exclusive discounts, early access to products, and personalized advice to encourage customers to opt-in to WhatsApp messaging. This helped me organically grow a list of highly engaged, interested customers—without spending a dime on paid ads.

2. Creating Valuable Content

I realized that just sending promotional messages would be a mistake. So, I took a content-first approach, using WhatsApp to share helpful tips, product tutorials, and behind-the-scenes updates. Through Botbuz, I automated the distribution of this content in a way that felt natural and conversational. Customers responded positively to the value I was providing and became more likely to engage with my promotional messages when they came through.

3. Automating Conversations for High Engagement

One of the biggest wins was using Botbuz WhatsApp API Services to automate customer interactions based on triggers. For example, when someone showed interest in a product, I could automatically send follow-up messages offering more information or a special discount. These timely and personalized messages helped convert leads into customers more effectively.

Moreover, I used WhatsApp groups to foster a sense of community. Customers who joined my WhatsApp groups were often the first to hear about new product launches or promotions. This exclusivity created a sense of belonging and increased customer loyalty.

4. Nurturing Relationships Through Personalization

While automation is key to scalability, I didn’t want to lose the personal touch. Through Botbuz, I ensured that my messages included personalized elements like customer names and past purchases. This helped maintain a human feel, even though many of the messages were automated.

For example, when someone made a purchase, they would automatically receive a thank-you message with their name, along with recommendations for future products they might like based on their previous purchase history.

5. Gathering Feedback and Insights

Finally, Botbuz WhatsApp API gave me the tools to gather customer feedback easily. After a purchase, customers would receive a short survey or an invitation to leave a review. This not only helped me improve my offerings but also provided social proof for future customers.

The insights gained through WhatsApp messaging were invaluable. I could track open rates, response times, and common queries, which helped me refine my marketing strategy continuously.

The Results : A Sustainable Growth Model

The impact of organic marketing through Botbuz WhatsApp API Services was transformative. Not only did I significantly reduce my reliance on paid ads, but I also saw a dramatic increase in customer engagement, retention, and satisfaction.

Higher Engagement : With personalized, timely messages, my open rates were much higher than email, and customer interactions felt more authentic and engaging.

Customer Loyalty : The personal touch, even through automation, led to increased customer loyalty. People appreciated the convenience and speed of communication.

Reduced Marketing Costs : I spent less on paid ads while reaching more people through organic marketing on WhatsApp.

Efficient Operations : With Botbuz's automation features, I saved hours of manual work every week, allowing me to focus on other aspects of growing my business.

Conclusion : The Future of Organic Marketing

As I look back on this journey, I’m amazed by how much using Botbuz WhatsApp API Services has changed the way I approach marketing. Organic marketing through WhatsApp is not just a trend; it’s a powerful strategy that leverages direct, personal communication with your audience. By investing in tools like WhatsApp API and taking a customer-first approach, you can build a sustainable, long-term growth model that doesn’t rely on expensive paid ads.

For any business looking to grow authentically and connect deeply with their customers, I can’t recommend Botbuz WhatsApp API Services enough. It has revolutionized my business, and I’m confident it can do the same for you.

Building Cross-Platform Apps with Swift and Kotlin

In today's tech-driven world, the demand for mobile applications that run seamlessly across different platforms is ever-increasing. Businesses and developers are constantly seeking efficient ways to reach a broader audience without duplicating efforts for multiple operating systems. Enter Swift and Kotlin, two powerful programming languages that, when combined, can streamline the process of building cross-platform apps. In this blog post, we'll explore how Swift and Kotlin can be used together to create high-performance, cross-platform applications.

Why Choose Swift and Kotlin?

Before diving into the technicalities, let's understand why Swift and Kotlin are the go-to choices for cross-platform app development.

Swift: Developed by Apple, Swift is a powerful and intuitive programming language designed for iOS, macOS, watchOS, and tvOS. It offers a robust set of features and is known for its performance and safety.

Kotlin: Created by JetBrains, Kotlin is a modern language that runs on the Java Virtual Machine (JVM) and can be used for Android development. Kotlin is concise, expressive, and interoperable with Java, making it a favorite among Android developers.

Both languages have gained immense popularity in their respective domains, and their capabilities make them ideal for cross-platform development.

Cross-Platform Development Approaches

There are several approaches to cross-platform development, each with its own set of advantages and trade-offs. Here are the main ones:

Native Development: Writing separate codebases for iOS (Swift) and Android (Kotlin). This approach ensures the best performance and user experience but requires maintaining two codebases.

Cross-Platform Frameworks: Using frameworks like Flutter, React Native, or Xamarin to write a single codebase that runs on both iOS and Android. While this saves time and effort, it may not fully leverage the native capabilities of each platform.

Kotlin Multiplatform: This approach allows you to write shared code in Kotlin for logic and business rules, while the platform-specific code is written in Swift for iOS and Kotlin for Android. This balances code reuse with native performance and experience.

Setting Up Your Development Environment

To get started with Swift and Kotlin for cross-platform development, you need to set up your development environment.

Swift Setup:

Install Xcode from the Mac App Store.

Create a new Xcode project and select the appropriate template for your app.

Kotlin Setup:

Install Android Studio from the official website.

Create a new Android project and configure it to use Kotlin.

Kotlin Multiplatform Setup:

Install the Kotlin Multiplatform plugin in Android Studio.

Create a new Kotlin Multiplatform project and configure the shared code module.

Writing Shared Code

With Kotlin Multiplatform, you can write shared code that can be used by both iOS and Android apps. This includes business logic, data models, and networking code.

Creating Shared Modules:

In your Kotlin Multiplatform project, create a shared module where you'll write your shared code.

Use Kotlin to write business logic and other shared functionalities.

Using Shared Code in Swift:

In your Xcode project, add a dependency on the shared module.

Use the shared code written in Kotlin within your Swift codebase.

Example: Networking Code

Let's look at an example of how you can write shared networking code in Kotlin and use it in both Swift and Kotlin.

Shared Networking Code in Kotlin:kotlinCopy codeimport io.ktor.client.HttpClient import io.ktor.client.request.get class ApiService { private val client = HttpClient() suspend fun fetchData(url: String): String { return client.get(url) } }

Using Shared Code in Swift:swiftCopy codeimport shared class DataFetcher { let apiService = ApiService() func fetchData(url: String, completion: @escaping (String) -> Void) { apiService.fetchData(url: url) { data, error in if let data = data { completion(data) } else if let error = error { print("Error fetching data: \(error)") } } } }

Conclusion

Building cross-platform apps with Swift and Kotlin offers a powerful combination of performance, efficiency, and code reuse. By leveraging the strengths of both languages and using Kotlin Multiplatform, developers can create high-quality applications that provide a native experience on both iOS and Android. As the mobile landscape continues to evolve, mastering these tools and techniques will be essential for staying ahead in the world of app development.

Embrace the power of Swift and Kotlin and start building cross-platform apps that deliver the best of both worlds!

Red Hat OpenShift Container Platform is a powerful platform created to provide IT organizations and developers with a hybrid cloud application platform. With this secure and scalable platform, you’re able deploy containerized applications with minimal configuration and management overhead. In this article we look at how you can perform an upgrade from OpenShift 4.8 To OpenShift 4.9. The OpenShift Container Platform 4.9 is supported on Red Hat Enterprise Linux CoreOS (RHCOS) 4.9, as well as on Red Hat Enterprise Linux (RHEL) 8.4 and 7.9. Red Hat recommends you run RHCOS machines on the the control plane nodes, and either RHCOS or RHEL 8.4+/7.9 on the compute machines. The Kubernetes version used in OpenShift Container Platform 4.9 is 1.22. In Kubernetes 1.22, a significant number of deprecated v1beta1 APIs were removed. There was a requirement introduced in OpenShift Container Platform 4.8.14 that requires an administrator to provide a manual acknowledgment before being able to upgrade the Cluster from OpenShift Container Platform 4.8 to 4.9. This helps to prevent issues after an upgrade to OpenShift Container Platform 4.9, where removed APIs are still in use by workloads and components in the Cluster. Removed Kubernetes APIs in OpenShift 4.9 The following is a list of deprecated v1beta1 APIs in OpenShift Container Platform 4.9 which uses Kubernetes 1.22: Resource API Notable changes APIService apiregistration.k8s.io/v1beta1 No CertificateSigningRequest certificates.k8s.io/v1beta1 Yes ClusterRole rbac.authorization.k8s.io/v1beta1 No ClusterRoleBinding rbac.authorization.k8s.io/v1beta1 No CSIDriver storage.k8s.io/v1beta1 No CSINode storage.k8s.io/v1beta1 No CustomResourceDefinition apiextensions.k8s.io/v1beta1 Yes Ingress extensions/v1beta1 Yes Ingress networking.k8s.io/v1beta1 Yes IngressClass networking.k8s.io/v1beta1 No Lease coordination.k8s.io/v1beta1 No LocalSubjectAccessReview authorization.k8s.io/v1beta1 Yes MutatingWebhookConfiguration admissionregistration.k8s.io/v1beta1 Yes PriorityClass scheduling.k8s.io/v1beta1 No Role rbac.authorization.k8s.io/v1beta1 No RoleBinding rbac.authorization.k8s.io/v1beta1 No SelfSubjectAccessReview authorization.k8s.io/v1beta1 Yes StorageClass storage.k8s.io/v1beta1 No SubjectAccessReview authorization.k8s.io/v1beta1 Yes TokenReview authentication.k8s.io/v1beta1 No ValidatingWebhookConfiguration admissionregistration.k8s.io/v1beta1 Yes VolumeAttachment storage.k8s.io/v1beta1 No v1beta1 APIs removed from Kubernetes 1.22 Table You are required to migrate manifests and API clients to use the v1 API version. More information on deprecated APIs migration can be found in the Official Kubernetes documentation. 1) Evaluate OpenShift 4.8 Cluster for removed APIs It is a responsibility of Kubernetes/OpenShift Administrator to properly evaluate all Workloads and other integrations to identify where APIs removed in Kubernetes 1.22 are in use. Ensure you’re on OpenShift Cluster 4.8 before trying to perform an upgrade to 4.9. The following commands helps you identify OCP release $ oc get clusterversions.config.openshift.io NAME VERSION AVAILABLE PROGRESSING SINCE STATUS version 4.8.15 True False 5h45m Cluster version is 4.8.15 You can then use the APIRequestCount API to track API requests – if any of the requests is using one of the removed APIs. The following command can be use to identify APIs that will be removed in a future release but are currently in use. Focus on the REMOVEDINRELEASE output column. $ oc get apirequestcounts NAME REMOVEDINRELEASE REQUESTSINCURRENTHOUR REQUESTSINLAST24H ingresses.v1beta1.extensions 1.22 2 364 The results can be filtered further by using -o jsonpath option: oc get apirequestcounts -o jsonpath='range .

items[?(@.status.removedInRelease!="")].status.removedInRelease"\t".metadata.name"\n"end' Example output: $ oc get apirequestcounts -o jsonpath='range .items[?(@.status.removedInRelease!="")].status.removedInRelease"\t".metadata.name"\n"end' 1.22 ingresses.v1beta1.extensions With API identified, you can examine the APIRequestCount resource for a given API version to help identify which workloads are using the API. oc get apirequestcounts .. -o yaml Example for the ingresses.v1beta1.extensions API: $ oc get apirequestcounts ingresses.v1beta1.extensions NAME REMOVEDINRELEASE REQUESTSINCURRENTHOUR REQUESTSINLAST24H ingresses.v1beta1.extensions 1.22 3 365 Migrate instances of removed APIs You can get more information on migrating removed Kubernetes APIs, see the Deprecated API Migration Guide in the Kubernetes documentation. 2) Acknowledge Upgrade to OpenShift Container Platform 4.9 After the evaluation and migration of removed Kubernetes APIs to v1 is complete, as an OpenShift Administrator you can provide the acknowledgment required to proceed. WARNING: It is a sole responsibility of administrator to ensure all uses of removed APIs is resolved and necessary migrations performed before providing this administrator acknowledgment. Run the following command to acknowledge that you have completed the evaluation and cluster can be upgraded to OpenShift Container Platform 4.9: oc -n openshift-config patch cm admin-acks --patch '"data":"ack-4.8-kube-1.22-api-removals-in-4.9":"true"' --type=merge Expected command output: configmap/admin-acks patched 3) Begin Upgrade from OpenShift 4.8 To 4.9 Login to OpenShift Web Console and navigate to Administration → Cluster Settings > Details Click on “Channel” and update channel to fast-4.9 or stable-4.9. Select fast-4.9 orstable-4.9 from the list of available channels. Channel can also be changed from the command line with below command syntax: oc adm upgrade channel clusterversion version --type json -p '["op": "add", "path": "/spec/channel", "value": "”]' Where  is replaced with either; stable-4.9 fast-4.9 candidate-4.9 New cluster updates should be visible now. Use the “Update” link to initiate upgrade from OpenShift 4.8 to OpenShift 4.9. Select the new version of OpenShift 4.9 that you’ll be upgrading to. The update process to OpenShift Container Platform 4.9 should begin shortly. You can also check upgrade status from CLI: $ oc get clusterversions.config.openshift.io NAME VERSION AVAILABLE PROGRESSING SINCE STATUS version 4.8.15 True True 2m26s Working towards 4.9.0: 71 of 735 done (9% complete) Output once all the upgrades are completed.

Mastering the AsyncAPI Specification: A Comprehensive Guide

The AsyncAPI Specification(A2S)

Credit

A portion of this content is derived from the excellent work of the OpenAPI Initiative team.

AsyncAPI 3.0.0 

Within this document, the terms “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” are to be interpreted in accordance with RFC 2119 regulations.

The Apache Licence, Version 2.0 governs the use of the AsyncAPI Specification.

Overview

A project called AsyncAPI Specification aims to provide machine-readable descriptions of message-driven APIs. You can use it for APIs that operate over any protocol (e.g., AMQP, MQTT, WebSockets, Kafka, STOMP, HTTP, Mercure, etc.) because it is protocol-agnostic.

A set of attributes that can be used in an AsyncAPI document to describe an application’s API is defined by the AsyncAPI Specification. The document is usually a single main document that contains the API description; it may refer to other files for more information or shared fields.

The actions that an application takes SHOULD be detailed in the AsyncAPI specification.

It indicates that messages from the userSignedUp channel will be received by the application.

Software topology, architecture, or pattern of any type is not assumed by the AsyncAPI definition. As a result, a server could be any type of computer programme that can send and/or receive data, including message brokers and web servers. But AsyncAPI has a feature called “bindings” that tries to assist with more detailed protocol details.

Deriving a receiver AsyncAPI document from a sender document, or the other way around, is NOT SUGGESTED. It is not guaranteed that an application sending messages will utilise the same channel that another application is using to receive them. Additionally, several fields in the document, such as the operation’s id, description, and summary, may cease to make sense.

By swapping out receive for send,IBM cannot presume that an opposing application exists automatically:

In addition to the problems listed above, there might be other configurations of the infrastructure that are not included here. A system might, for example, utilise one read-only channel for messages, another for sending them, and a middleman process to forward messages between the channels.

Definitions

Server

A message broker that can send and/or receive messages between a sender and a recipient MAY be a server. A server could be a WebSocket API service that allows message-driven server-to-server or browser-to-server communication.

Application

Any type of computer programme, or collection of them, is called an application. A sender, a recipient, or both MUST be involved. An application could be a message broker, microservice, mainframe process, Internet of Things device (sensor), etc. Any number of programming languages may be used to create an application, provided that they support the chosen protocol. To connect and send messages, an application MUST also use a protocol that the server supports.

Sender

An application that sends messages to channels is called a sender. Senders may choose to send to more than one channel, based on the use-case pattern, protocol, and server.

Receiver

An application that receives messages from channels is called a receiver. Recipients may get data from various channels, contingent upon the server, protocol, and use-case design. A message that is received MAY be forwarded again by the recipient unaltered. Recipients MAY respond to the communication by acting as consumers. It is possible for a receiver to function as a  processor, combining several messages into one and sending it.

Message

The method by which data is transferred across a channel between servers and applications is called a message. Both headers and a payload are possible components of a message. It is possible for the headers to be separated between header attributes defined by the application and protocol-defined headers, which can serve as supporting metadata. The application-defined data, which must be serialised into a format (JSON, XML, Avro, binary, etc.), is contained in the payload. A message can handle various interaction patterns, including event, command, request, and response, because it is a generic mechanism.

Channel

A channel is an addressable element that the server provides for message organisation. Applications that are senders send messages to channels, and applications that are receivers receive messages from channels. Multiple channel instances MAY be supported by servers, enabling messages with various content types to be addressed to various channels. Protocol-defined headers MAY allow the channel to be included in the message, depending on how the server is implemented.

Protocol

The method (wireline protocol or API) by which messages are transferred between the application and the channel is called a protocol. Mercure, AMQP, HTTP, JMS, Kafka, Anypoint MQ, MQTT, Solace, STOMP, Mercure, WebSocket, Google Pub/Sub, and Pulsar are a few examples of protocols.

Bindings

A method for defining protocol-specific data is called a “binding” (also known as “protocol binding”). As a result, a protocol binding MUST only define data related to the protocol.

Specifications

Format

The files that follow the JSON standards and describe the message-driven API in line with the AsyncAPI Specification are represented as JSON objects. An A2S (AsyncAPI Specification) file can also be represented in YAML, which is a superset of JSON.

When a field is said to have an array value, for instance, the JSON array format is employed:

Although the API uses JSON to describe itself, the API does not require JSON input or output.

The specification uses case sensitivity for all field names.

Two kinds of fields are exposed by the schema. Patterned fields specify a regex pattern for the field name, whereas Fixed fields have a specified name. As long as each occurrence of a patterned field has its own name, they can appear more than once.

YAML version 1.2 is advised coupled with a few further restrictions to maintain the ability to round-trip between YAML and JSON formats:

Only tags that are permitted by the JSON Schema standard may be used.

The YAML Failsafe schema guideline stipulates that keys used in YAML maps MUST be restricted to a scalar string.

File Organisation

An AsyncAPI document MAY consist of a single document or, at the author’s option, be composed of several related portions. The latter scenario makes use of Reference Objects.

It’s crucial to remember that, aside from the Components Object, everything defined in an AsyncAPI document MUST be used by the implemented Application. Every definition contained within the Components Object designates a resource that the implemented Application MAY or MAY NOT use.

Asyncapi.json or asyncapi.yaml is the standard name for the AsyncAPI Specification (A2S) file.

URLs that are absolute

RFC3986, section 4.3 defines all characteristics that are absolute URLs, unless otherwise noted.

Schema

AsyncAPI Object

The API specification’s root document object is this one. It is a single document that includes both the API declaration and resource listing.
