# S2S Postback Setup

## Server-to-server payout

To facilitate the delivery of rewards to your users, Adjump offers a secure and transparent method known as **Server-to-Server Payouts**. This approach ensures that you have full control over how rewards are distributed and provides enhanced security for your users' benefits.

To notify you about rewards and deliver relevant information, Adjump will initiate an **HTTP GET request** to your configured endpoint.
