messages

Reply to an issue

Sends a customer-facing reply on an issue, visible to the requester.

message_id is required to identify which existing customer-visible conversation or thread to continue. Use the top-level message id returned by GET /issues/{id}/messages; do not use an external provider's message ID or the nested email_info.message_id value.

For an email conversation, email_info must contain at least one recipient across to_emails, cc_emails, and bcc_emails. The referenced message controls email threading, but its recipients are not copied automatically.

Rate limit: 10 requests per minute
