WhatsApp Business API integration

How to integrate WhatsApp Business API into your stack with webhooks, templates, and auth.

Integrating WhatsApp Business API means handling auth, templates, sending messages, and webhooks. This overview keeps you on track.

Key takeaways

Obtain access tokens and store them securely.
Use templates for business-initiated messages; session messages for user-initiated replies.
Set up webhooks to receive delivery receipts and replies.

Integration steps

Get API credentials and a test number.
Configure webhooks and verify signatures.
Create/approve templates for outbound messaging.
Send test messages (text, template, media) to whitelisted numbers.

Auth and security

Store tokens in env variables; rotate when needed.
Validate webhook signatures to ensure authenticity.
Log message IDs and statuses for auditability.

Testing and rollout

Start in sandbox/test numbers before production.
Monitor delivery and block rates; adjust templates.
Implement retries/backoff for transient errors.

FAQs

Do I need a dedicated server?

Not for Cloud API. On-prem/legacy hosting requires managed infrastructure, but most teams use Cloud API or a BSP platform.

Can I integrate without coding?

Platforms like BotMax AI provide UI-based flows. For custom logic, use REST/SDKs.

What about rate limits?

Check provider or Cloud API limits; implement throttling and error handling accordingly.
