Send Message to a WhatsApp Channel

To send a message to a WhatsApp Channel, follow these steps:

First, listen for the message.upsert event. This event will include the channel's unique ID (e.g., 123456789@newsletter) in the jid field.
Once you have the channel ID, use it in the to field when sending a message through your usual send endpoint.
The message parameters are the same as those for regular messages. Just ensure the to field is set to the channel's ID.

⚠️ Important: Currently, only text messages can be sent to a channel.

Parameters

Name	Type	Required	Description
to	string	Yes	Channel ID (e.g., '123456789@newsletter') .
