Developer & API

Definition
The unique identifier assigned to every WhatsApp message, used to track its status and correlate replies and receipts.

What WhatsApp Message ID means

A wamid is the unique identifier the WhatsApp Business Platform assigns to each message. It is returned when you send a message and appears in the status webhooks (sent, delivered, read, failed) for that message, so you can correlate a delivery event back to the exact message you sent.

The wamid is also used to reply in context or to reference a specific message. Because it is globally unique and stable, it is the key developers use to build reliable tracking and reconciliation.

InfiQ exposes message IDs through its API and webhooks so developers can match outbound sends to their delivery and read outcomes.
