To use the Google Forms API prior to General Availability, your Google Cloud project must be allowlisted. To request that your project be allowlisted, complete the Early Adopter Program application (below).
The API is currently in Open Beta, and we anticipate promoting the API to GA in 2022. Starting now, you will be able to make your integrations public if approved for the program.
Completion of the application doesn't guarantee enrollment in the program, but if you're approved for Early Adopter Access, you'll be able to start developing integrations using the Forms API. We'll also send you important updates about the Open Beta and improvements to the API as development progresses.
