Learn WhatsApp Business API. Build with confidence.
Guides and practical resources for businesses, developers, SaaS teams and agencies working with WhatsApp Business API — written against the behaviour of the live platform, not a rewrite of Meta's documentation.
Read in this order
Four guides that build on each other. Each one is written against the behaviour of the live platform rather than Meta's documentation alone, and each carries the date it was last checked — WhatsApp's pricing and delivery semantics change independently of us.
- 1What is a WABA?August 2026
Start here if the vocabulary is new. A WhatsApp Business Account is not the app on your phone, and the difference decides what you can and cannot do through the API.
- 2Send your first WhatsApp API messageAugust 2026
The shortest path from credentials to a message that actually arrives — the request, the response, and how to tell whether it worked.
- 3How WhatsApp webhooks actually workAugust 2026
Once messages flow, events flow back. What Meta sends, what a delivery receipt does and does not prove, and how to handle the payloads without losing any.
- 4WhatsApp API pricing explainedAugust 2026
Read before you commit to volume. There are two separate bills, and the one most comparisons omit is usually the larger of the two.
All resources
What is a WABA?
How WhatsApp Business Accounts, phone numbers and templates fit together — and what you actually need before you can send a message.

Where WhatsApp events come from, what a delivery receipt really tells you, and why webhooks mean different things on different platforms.
Send your first WhatsApp API message
A working request against the WA Console API — the headers, the body, what comes back, and how to read what happened next.
WhatsApp API pricing explained
Why there are two bills, what each one is for, and how to estimate cost without being surprised by the half nobody mentions.
