Amazon Publisher Services (APS) provides a HeaderBidding solution so publishers can use real-time bidding for content advertsements. The APSClientLibrary is a library that provides a single API for Amazon Publisher apps to retrieve device parameters. You can compile your bid request and send it to APS through a client-to-server (C2S) or server-to-server (S2S) integration. For Amazon Publisher Services API installation instructions, see @amazon-devices/kepler-aps-client.

Amazon Publisher Services integrations

Amazon Publisher Services offers publishers two distinct integration paths for the Vega TV platform. These integrations allow publishers to submit bid requests to fill their ad break inventory.

The C2S integration

Publishers use a C2S call that returns the bid information to the publisher ad server as custom key values. You can only call our server from your app, since we don’t support server-side calls with this integration.
  • API Protocol: HTTPS
  • Endpoint:
  • Recommended Timeout: 1000 ms
See the C2S integration guide for more information.

The S2S integration

Publishers retrieve APS key value pairs using an S2S back-end call that returns the bid information to the publisher ad server. You can call our server only from your server, since we don’t support client-side calls.
  • API Protocol: HTTPS
  • Endpoint: .
  • Recommended Timeout: 500 ms.
See the S2S integration guide for more information.
