WhatsApp Business API integration means connecting your own software to WhatsApp so it can send messages and receive status updates automatically. If you are wiring WhatsApp into your own product, you need the real identifiers and the real status events. Both are exposed rather than hidden behind a simplified wrapper.
Included in the platform licence. Not a paid add-on.
The short version
WhatsApp business API integration in brief
WhatsApp Business API integration with WappBlaster gives developers a REST endpoint for sending and a webhook URL for receiving status, on a messaging platform run by a Meta Tech Provider. The detail that saves the most engineering time is reconciliation: the send response includes the message ID Meta itself assigns, and any reference you attach, such as an order or ticket number, comes back inside each delivered, read or failed event, so no mapping table is needed. Going live takes 4 steps: obtain credentials for the registered channel, run a test send with the documented Postman collection, point the status webhook at your stack, then add your reference IDs. A file upload API handles images and PDFs for messages and templates. For teams with no time to build sends, an inbound webhook trigger lets any system able to call a URL start a bot flow or automation. Typical uses include OTP delivery, internal alerts and SaaS products messaging their own customers.
You call a REST endpoint from your backend to send messages, and point a webhook at your system to receive delivery, read and failure statuses back from Meta.
WappBlaster returns Meta's own WhatsApp message ID on every send and echoes your custom reference IDs in webhook payloads, so events map to your records.
Meta's identifier comes back on each send, matching Meta's own reporting.
Your order or ticket reference rides along and returns in each status event.
Delivery and read events flow into your stack as they happen.
Any system able to call a URL can start a WappBlaster flow.
The WhatsApp API lets your own systems send and track messages programmatically. WappBlaster exposes a REST send-message API that returns Meta’s own WhatsApp message ID, a configurable webhook URL that receives delivery, read and failure statuses from Meta, custom reference IDs echoed back in webhook payloads, a file upload API for media, and inbound webhook triggers that start bot flows or automations.

Straight answers about WhatsApp business API integration.
Yes. You can send messages for your official WhatsApp number over REST, and the documentation includes a Postman walkthrough. The response includes Meta’s own WhatsApp message ID.
Link to this answerSet a webhook URL on the channel and Meta’s status events (sent, delivered, read, failed) are forwarded to it as they occur.
Link to this answerYes. Send a custom reference ID with the API call and it comes back in the webhook payload, so events map to your records without a separate lookup.
Link to this answerNo. Everything in the platform works without code. The API is there for teams that want to drive WhatsApp from their own product, not a prerequisite for using it.
Link to this answerAPI access, status webhooks and the file upload API sit within the standard licence, billed once a year at a flat rate. On top of that, Meta's charge for each message is passed on unchanged.
Link to this answerYes. It offers a REST send-message API, status webhooks, custom reference IDs, a file upload API and inbound webhook triggers, with a Postman walkthrough to test against your own number.
Link to this answerYes. Authentication templates can be fired from your own auth service to deliver one-time passcodes, using the same send-message API as any other template.
Link to this answerUse the file upload API. It sends media to the platform programmatically so the files can be used in messages and in templates.
Link to this answerStart with the inbound webhook trigger. Any system able to call a URL can start a bot flow or automation, which is simpler than building a full send integration, and the REST API can come later.
Link to this answerYes, that is one of the listed uses. SaaS products can embed WhatsApp and send on behalf of their own customers through the API.
