Guide to the official WhatsApp Business API documentation and what developers should focus on.

The official WhatsApp Business API documentation covers Cloud API, templates, webhooks, and message formats. Here’s what to focus on first.

Key takeaways

Review message types, templates, and webhooks before coding.
Use provider SDKs or REST examples to speed up integration.

Docs to read first

Authentication and access tokens.
Message types: text, media, interactive, templates.
Webhooks: setup, verification, and event payloads.
Templates: categories, variables, and submission rules.

Helpful resources

Cloud API reference for latest endpoints and payloads.
Sample cURL/JSON requests for quick testing.

Integration tips

Use environment variables for tokens and webhook secrets.
Start with a test number and whitelisted recipients.
Validate payloads against the docs to avoid format errors.
