Versioning
Prism is versioned in the URL path. The version is the first path segment of https://prism.adgem.com, and a new version never changes the base URL. The current version is v1:
POST https://prism.adgem.com/v1/offers
- Additive, backward-compatible changes (for example, new fields or queries) are made within the current version. Because a GraphQL client requests only the fields it names, new fields don't affect existing queries — select just what you use.
- Breaking changes would be introduced under a new version path (for example,
/v2), with the current version remaining available during any migration window.
targeted-api.adgem.comPrism previously answered on https://targeted-api.adgem.com. That host still resolves and serves
the same API, but it is deprecated and will be retired on 15 February 2027. Point your base URL
at https://prism.adgem.com before then — nothing else about your integration changes.
Responses to authenticated requests on the old host carry Deprecation and Sunset headers, plus a
Link header pointing at the same path on prism.adgem.com, so a client can detect the move without
reading this page. An unauthenticated request is rejected before those headers are added, so check on
a real call.
When changes ship, they're recorded in the Changelog. If you're moving from an older integration, see Migrations.
