Webhook: Newsletter Message Received

Webhooks

Event is triggered when a message is received in a newsletter (channel) the session is subscribed to.

Webhook Event: messages-newsletter.received

This event is triggered when a new message is published in a newsletter (also known as a Channel) that your session is subscribed to.

The payload includes the message content and the unique JID of the newsletter, which typically ends in @newsletter. Unlike group messages, a participant field is not needed as the sender is the newsletter itself.

See the code example below for a typical payload structure.
