Typical Workflow
Use this endpoint as part of a WhatsApp message-sending flow:- Check session status before sending a message.
- If
can_send_freeformistrue→ use Send Freeform Message. - If
requires_templateistrue→ use Send Template Message.
Notes
- The 24-hour window is based on the customer’s last inbound message timestamp.
- Each new customer message resets the 24-hour timer.
- This endpoint is read-only and does not consume any Famulor balance.
