# Sportsbook / Affiliate IDs

Each sportsbook tracked by TheRundown API is identified by a numeric `affiliate_id`. These are the values returned in API responses within odds/line objects and are used with the `affiliate_ids` filter parameter to request lines from specific books.

| ------------- | ------------ |
| Bovada        | 2            |
| Pinnacle      | 3            |
| Sportsbetting | 4            |
| BetOnline     | 6            |
| LowVig        | 11           |
| Bodog         | 12           |
| Intertops     | 14           |
| Matchbook     | 16           |
| YouWager      | 18           |
| DraftKings    | 19           |
| Unibet        | 21           |

| Kalshi        | 25           |

<Note>
  These IDs are used in the `affiliate_ids` query parameter to filter which sportsbooks are included in the response. For example, `affiliate_ids=19,23` returns lines from DraftKings and FanDuel only.
