V2025 Forms API Released!
August 22nd, 2025 by Formstack Developers
The Formstack team has been working hard to bring you a modern version of our Forms API, called V2025. This new version is built with the OpenAPI spec and includes an LLMs.txt file to enable your AI Assistant tools. V2025 currently has feature parity with the Forms V2 API, so getting started or switching over is easy! The authentication process is different between the two versions, so be sure to read up on the new Personal Access Tokens in the Formstack Admin app and then dive in to creating something great.
