# Mapping Feeds

The Mapping Feeds in this API serve two specific purposes:

* **Linking IDs between APIs** — If you are using both the NFL API and the Global American Football API, these feeds allow you to cross-reference entity IDs between the two products, so that teams, competitors, and players can be consistently identified across both.
* **Resolving merged IDs** — In cases where duplicate competitor or player records have been consolidated into a single unique ID, these feeds surface that relationship so you can update any stored references accordingly.

  ### Tip:

  For broader entity ID mapping across Sportradar products — including competitions, sport events, seasons, and players — the <Anchor label="Mapping API" target="_blank" href="https://developer.sportradar.com/odds/reference/mapping-overview">Mapping API</Anchor> offers a more scalable, dedicated solution. If your use case extends beyond NFL and Global American Football ID linking, we recommend starting there.
