What the WhatsApp engine handles for you
02
Use approved templates
Configure the approved Meta template name, language, and parameters in your Sendrin template. Sends use the Meta Cloud API template-message format.
03
Record recipient consent
Record a recipient opt-in before sending. The consent ledger also records supported inbound STOP replies so your integration can respect opt-outs.
04
Inspect delivery receipts
Authenticated Meta callbacks update notification delivery status. Use the console to investigate provider failures and recipient consent issues.
