# API Documentation

> Chatarmin guide: API Documentation

Chatarmin's Public API lets you integrate WhatsApp marketing and messaging into your own systems.

[Find the full API reference here](https://apidocs.chatarmin.com/reference/api-overview). Reach out to our FinAI chatbot in your Chatarmin dashboard if you need help finding an endpoint.

## Sending messages via the API

Sending WhatsApp messages through the Public API (`POST /messages/send`) requires **API message sending** to be enabled on your Chatarmin account. This is a paid add-on.

If message sending is not enabled for your account, the API returns a `403` response with a message asking you to contact the Chatarmin team to enable API access.

<Note>
  Contact the Chatarmin team through your dashboard support channel to request API message sending for your account.
