# API Authentication

You must use an authentication token to interact with DT Fairbid APIs. To obtain an authentication token, send your verification key through the appropriate authentication endpoint.

* [DT FairBid Management API](https://docs.digitalturbine.com/dt-fairbid/advanced-configurations/dt-fairbid-management-api) - Allows publishers to create and maintain all settings required to monetize their apps with ads.
* [DT FairBid Reporting API](https://docs.digitalturbine.com/dt-fairbid/reporting/reporting-api/dt-fairbid-reporting-api) - Gives access to all the reporting data from the monetization ad units. You can query multiple metrics such as revenue and impressions and filter by the available dimensions.
* [DT FairBid User Level Reporting API](https://docs.digitalturbine.com/dt-fairbid/reporting/reporting-api/dt-fairbid-user-level-reporting-api) - Gives access to reporting data to measure all revenue generated from individual device users. Use this information to optimize retargeting campaigns and accurately measure user lifetime value (LTV).
