Introduction
A custom-built WhatsApp Business API integration designed from the ground up to handle high-volume communication workflows. This API serves as the backbone for multiple client projects requiring reliable, scalable messaging.
How it Works
The API abstracts the complexity of the WhatsApp Business Platform into a clean, developer-friendly interface:
- Message Routing — intelligent routing of inbound messages to the correct handler based on conversation context and keywords.
- Template Management — programmatic creation and management of WhatsApp message templates with approval workflow tracking.
- Media Handling — support for images, documents, and rich media messages with automatic format optimization.
- Webhook Processing — reliable webhook ingestion with retry logic and dead-letter queuing for failed deliveries.
- Rate Limiting — built-in rate limiting and queue management to stay within WhatsApp's API constraints.
