Typical Workflow

Use this endpoint as part of a WhatsApp message-sending flow:

  2. If can_send_freeform is true → use Send Freeform Message.
  3. If requires_template is true → 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.
