Atom WhatsApp Templates API
REST service for sending pre-approved WhatsApp template messages from an account's official WhatsApp number. The documented send endpoint is POST /api/Template/SendMessage, taking templateId, phoneNumber, clientName, groupName, an assign flag and a params object of template variables; a /templates endpoint exposes the account's templates. Requests carry Content-type application/json and an Authorization Bearer token. When the number is already in an open conversation the message is delivered immediately, otherwise confirmation is awaited from the official WhatsApp provider. No OpenAPI is published for this API.
