Postback (Server-to-Server Callback)

Definition

A postback is a server-to-server HTTP request that notifies your server when a user completes an offer. Unlike client-side callbacks, postbacks are reliable because they don't depend on the user's device being online. They include cryptographic signatures for security.

How It Works

RewardingHub sends postbacks within seconds of offer completion. Each postback includes the user ID, reward amount, offer ID, and an HMAC-SHA256 signature for verification. See our webhook integration guide for code examples.
