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