Authentication

Send your API key on every request:
See Authentication for setup and verification.

How this tab is organized

The API reference includes core integration endpoints plus setup and account-management helpers. For most server-side integrations, start with Messages, Channels, Contacts, Templates, Media, Webhooks, and API keys.

Playground

  1. Open an operation page (for example Send a message).
  2. Enter your X-Api-Key in the playground auth field.
  3. Pick an example from the dropdown (text, template, buttons, …) or edit the body.
  4. Run the request against https://api.wazapin.com.
If the playground fails behind your proxy, allow POST to /_mintlify/api/request. See API playground.

Message guides vs OpenAPI

Step-by-step message types (limits, examples) live under Sending & receiving. OpenAPI pages document HTTP shape and schemas.
Start with Send a message for the full type reference and playground examples.
