automations/highlevel-send-message.automation.ts
Input

{ account } selects a named HighLevel binding.
Output
This action calls
POST /conversations/messages with HighLevel API version 2021-04-15 and requires conversations/message.write. HighLevel validation and permission errors fail the action. Rate limits honor the provider’s retry timing. Automate.ax does not automatically replay this create or send operation after an indeterminate transport failure.
