WhatsApp Business API Development
WhatsApp Business API Developer for Custom Integrations & Automation
I build custom WhatsApp Business API solutions using the official WhatsApp Business Platform and Cloud API. My work includes API integrations, chatbots, CRM workflows, webhooks, message templates, automated notifications, and complete business communication systems.
Whether you are starting with WhatsApp Cloud API for the first time or already have an existing integration, I can help connect WhatsApp with your website, CRM, ecommerce platform, database, SaaS product, or custom business software.
What I Can Build
What I Can Build With WhatsApp Business API
The WhatsApp Business API can be used for much more than simply sending messages. I build complete communication and automation systems around the way a business already works.
Depending on the project, WhatsApp can connect with your CRM, website, ecommerce platform, database, APIs, internal software, and automation workflows so conversations can trigger real business actions.
Customer Communication Systems
Build structured WhatsApp communication for customer enquiries, support conversations, updates, follow ups, and ongoing business messaging.
AI Chatbots & Automated Conversations
Create WhatsApp chatbots for FAQs, lead qualification, information collection, customer support, automated replies, and human handoff.
CRM & Lead Management
Connect WhatsApp with CRM systems so contacts, conversations, lead status, follow ups, and sales activity can stay organized automatically.
Automated Notifications
Send workflow based messages for orders, appointments, bookings, deliveries, payments, reminders, account activity, and customer updates.
Website & Ecommerce Integration
Connect WhatsApp with websites and ecommerce systems so forms, orders, customer actions, and business events can trigger messaging workflows.
Custom API Integrations
Connect WhatsApp with external APIs, databases, SaaS products, internal software, and other systems your business already depends on.
Campaign & Follow Up Workflows
Build organized WhatsApp campaign workflows for audience segmentation, customer follow ups, lead nurturing, reminders, and communication sequences.
Custom WhatsApp Dashboards
Build dashboards and internal tools for managing conversations, contacts, messaging activity, automation workflows, and business data around WhatsApp.
WhatsApp Cloud API Setup & Integration
Set Up the Official WhatsApp Cloud API for Your Business
A reliable WhatsApp Business API system starts with the correct Cloud API setup. I handle the technical configuration required to connect your business, phone number, Meta application, and backend system with the official WhatsApp Business Platform.
Once the connection is configured, I integrate the Cloud API with your application so it can send messages, receive customer replies, process message events, and communicate with the other systems your business uses.
Meta App Configuration
I configure the Meta application and WhatsApp product required to connect your software with the official WhatsApp Business Platform and Cloud API.
WhatsApp Business Account
I connect and configure the WhatsApp Business Account, business assets, phone number details, and the identifiers required by your integration.
Business Phone Number Setup
I configure the business phone number and Phone Number ID so your application can send and receive WhatsApp messages through the Cloud API.
Access Tokens & Permissions
I configure the required permissions, access tokens, system users, and authentication needed for secure communication between your application and Meta APIs.
Send & Receive Messages
I connect the Cloud API with your backend so your application can send messages, receive customer replies, process conversations, and trigger business workflows.
Production Configuration
I prepare the integration for real business use with secure configuration, error handling, logging, message tracking, and reliable backend processing.
Already Have WhatsApp Cloud API Set Up?
I can also work with an existing setup. If your Meta application, WhatsApp Business Account, or phone number is already configured, I can review the current integration and continue with webhooks, messaging, automation, CRM connections, chatbots, or other custom development.
Messages, Templates & Webhooks
Build Reliable WhatsApp Messaging & Event Workflows
Once the WhatsApp Cloud API is connected, the next step is building the messaging layer that actually powers customer communication. I integrate outgoing messages, approved templates, incoming replies, media, and webhook events into your application.
This allows your backend to understand what is happening inside each conversation, track message delivery, react to customer replies, and trigger the correct business workflow automatically.
Text & Media Messages
I integrate WhatsApp messaging for text, images, documents, videos, and other supported message types so your application can communicate with customers programmatically.
WhatsApp Message Templates
I integrate approved message templates for reminders, notifications, marketing messages, authentication, follow ups, and other business communication workflows.
Template Variables & Media
I configure dynamic template parameters, customer information, media headers, documents, images, and other content required by your approved WhatsApp templates.
Incoming Message Webhooks
I build webhook handlers that receive customer messages and pass them into your chatbot, CRM, database, support system, or custom business workflow.
Message Status Tracking
I process sent, delivered, read, and failed message events so your application can track messaging activity and respond correctly when delivery problems occur.
Automated Message Workflows
I connect messaging events with business logic so customer activity, CRM changes, orders, bookings, or other system events can trigger the right WhatsApp messages.
More Than Just Sending a Message
A production WhatsApp integration needs to handle both outgoing and incoming activity correctly. I build the logic around message delivery, customer replies, template usage, webhook events, and backend actions so WhatsApp becomes part of a complete business system rather than a disconnected messaging channel.
WhatsApp Chatbots & Conversation Automation
Turn WhatsApp Conversations Into Automated Business Workflows
I build WhatsApp chatbots that do more than send predefined replies. They can understand where a customer is in the conversation, collect information, qualify leads, answer common questions, and trigger actions inside your business systems.
The chatbot can connect with your CRM, database, website, APIs, and internal tools so each conversation can become part of a larger customer support, sales, lead management, or automation workflow.
Automated Conversation Flows
I build structured WhatsApp conversation flows that can answer common questions, collect information, guide customers through options, and respond based on what they need.
AI Assisted Conversations
I can integrate AI into WhatsApp workflows for more flexible responses, knowledge based answers, customer support, lead handling, and natural conversation experiences.
Lead Qualification
The chatbot can ask targeted questions, collect lead details, understand customer intent, and qualify prospects before sending them to your sales or support team.
Conditional Logic
I build conversation paths that change based on customer replies, selected options, lead status, previous activity, CRM data, or other business conditions.
Human Handoff
When a conversation needs a real person, I can route it to the right team member while preserving the customer details and conversation context.
Business Workflow Actions
WhatsApp conversations can create leads, update CRM records, save customer information, trigger notifications, call APIs, and start other automated business workflows.
Automation With a Clear Human Handoff
Not every conversation should stay automated from beginning to end. I can design the workflow so routine questions and data collection are handled automatically, while important, complicated, or high value conversations move to a real team member at the right time.
CRM, Website & Ecommerce Integrations
Connect WhatsApp With the Systems Your Business Already Uses
WhatsApp becomes much more useful when it is connected with the rest of your business. I build integrations that connect customer conversations with your CRM, website, ecommerce platform, database, APIs, and internal software.
This allows information to move automatically between systems. A customer message can create a lead, update a CRM record, check an order, trigger a notification, save information, or start another business workflow without requiring someone to copy data manually.
CRM Integration
I connect WhatsApp with CRM systems so customer details, conversations, lead status, follow ups, and sales activity can stay organized automatically.
Website Integration
I connect WhatsApp with websites, forms, registrations, enquiries, bookings, and other user actions so messages and workflows can start automatically.
Ecommerce Integration
I build WhatsApp workflows for order confirmations, delivery updates, customer notifications, abandoned cart follow ups, and other ecommerce communication.
Database Integration
WhatsApp conversations can read from and write to your database so customer information, lead data, order details, and workflow activity stay synchronized.
Third Party API Integration
I connect WhatsApp with external APIs and services so conversations can trigger actions, fetch information, update systems, and automate processes across different platforms.
Custom Business Workflows
I connect WhatsApp with dashboards, SaaS products, support systems, internal tools, and custom software built around the way your business already works.
Keep Customer Data Connected
The goal is to avoid having WhatsApp operate as a separate system. I can connect conversations with the data and tools your team already uses so customer activity stays organized and the right actions happen automatically.
Automated Notifications & Business Workflows
Turn Business Activity Into Automated WhatsApp Messages
WhatsApp messages can be triggered automatically when something happens inside your business, so customers receive the right information without your team sending every update manually.
I build workflows that connect WhatsApp with your CRM, website, ecommerce platform, booking system, database, or custom software so business events can automatically trigger the appropriate customer communication.
Order Confirmations
Send WhatsApp confirmations when a customer places an order, including order details, reference numbers, payment information, and next steps.
Delivery & Shipping Updates
Keep customers informed with automated shipping, dispatch, delivery, and status updates triggered by changes inside your ecommerce or order management system.
Appointment & Booking Reminders
Send confirmations, reminders, rescheduling information, and follow ups for appointments, consultations, reservations, and other scheduled services.
Payment Notifications
Trigger WhatsApp messages for payment confirmations, pending payments, invoice updates, subscription activity, and other billing related events.
Customer Follow Ups
Automatically follow up with customers based on previous conversations, lead status, purchases, enquiries, appointments, or other business activity.
Custom Business Alerts
Create notification workflows for account activity, support updates, internal alerts, service changes, application events, or any other business process that needs WhatsApp messaging.
Built Around Your Existing Workflow
The trigger can come from almost any connected system, such as a new order, booking, payment, CRM update, support request, or database change. I build the logic that decides when a message should be sent, what information it should contain, and what should happen after the customer responds.
Existing WhatsApp API Troubleshooting
Already Have a WhatsApp Integration That Isn't Working Properly?
You do not always need to rebuild an existing WhatsApp Business API integration from the beginning. I can review the current setup, identify where the problem is happening, and fix the parts that are preventing the system from working correctly.
This can include Cloud API configuration, webhooks, message delivery, templates, authentication, CRM connections, chatbot workflows, or custom backend logic.
Webhook Problems
I troubleshoot webhook verification, incoming message events, duplicate events, missing callbacks, status updates, and backend processing issues.
Message Delivery Issues
I investigate messages that are not sending, not being delivered, failing unexpectedly, or returning API errors that need to be handled correctly.
Template Issues
I help identify problems with message templates, parameters, media headers, template configuration, and sending approved templates through the API.
Authentication & Access
I troubleshoot access tokens, permissions, system users, phone number configuration, business assets, and authentication problems affecting the integration.
Broken Integrations
I review issues between WhatsApp and your CRM, website, database, APIs, chatbot, or custom backend when data or workflows are not behaving correctly.
Production Reliability
I help improve error handling, logging, message status tracking, retries, backend logic, and other parts of the integration that affect reliability in real use.
Existing Code Is Fine
If you already have a working codebase, I can work with the existing implementation instead of replacing everything. The goal is to understand what is failing, fix it properly, and improve the integration where needed.
Real WhatsApp Product Experience
Experience From Building a Complete WhatsApp Automation Platform
My WhatsApp Business API experience does not come only from individual integrations. I have also built WupHub, a complete WhatsApp communication and automation platform designed around real business messaging workflows.
Building a full product required me to think beyond simply connecting an API. I had to work across messaging, automation, backend systems, customer data, workflows, integrations, and the overall experience of turning WhatsApp into a usable business platform.
WhatsApp Automation
Building WupHub gave me practical experience creating WhatsApp communication and automation workflows for real business use.
Backend & API Development
The platform required backend systems, APIs, webhooks, message processing, business logic, and connections between different parts of the application.
Automation Workflows
I built workflows around campaigns, customer communication, follow ups, business events, and other actions that need to happen automatically.
AI Assisted Conversations
Working on automated conversations and AI assisted messaging helped me understand how intelligent responses can fit into practical WhatsApp workflows.
Data & Customer Management
Building a complete platform also involved managing contacts, application data, customer activity, automation states, and information used across different workflows.
Building the Product Changed How I Approach WhatsApp Projects
Working on a complete WhatsApp product taught me to think about reliability, user workflows, backend architecture, automation logic, integrations, and what happens after a system is deployed. I bring that same product thinking into custom WhatsApp Business API projects.
