This document describes TopOn's Ad Impression Revenue Server-Side Callback API (S2S), which allows developers to receive real-time callbacks of ad impression events on their own server.
Precautions
- Developers must ensure their server has sufficient capacity to receive the data. We recommend that the developer's server only receives the data, and that any subsequent processing be handled by a separate service or other asynchronous logic. Note: TopOn does not retry when a callback fails.
- Developers must implement their own deduplication, using the combination of
req_idandadsource_idas the deduplication key. - On a successful callback, the developer's server must respond with HTTP status code 200. Any other status code is treated as a failure.
- Please contact your Account Manager (AM) to enable this feature and to provide your receiving endpoint (callback URL).
