The Interactive Advertising Bureau (IAB) developed ads.txt in 2017. Ads.txt is a framework that defines how publishers should list their authorized monetization partners. Using this file, the buy-side can identify which sellers the publisher has authorized to sell their inventory.
The IAB released the app version for ads.txt called app-ads.txt. The specification is an extension of ads.txt.
The simple app-ads.txt standard helps prevent the unauthorized selling of in-app inventory and app domain spoofing.
To verify authorized seller status, follow the instructions below:
These steps apply to all parties in the ecosystem - from sell-side platforms via exchanges to buy-side platforms.

- Buyer crawls the app listing page the in app store
- The Developer URL is translated into an app-ads.txt path
- The app-ads.txt file is crawled and interpreted
