APIs are the foundation of modern integrations. They’re how businesses connect systems, automate workflows, and deliver experiences faster. With the launch of the Formstack Forms 2025 API (V2025), we’re making it easier and safer for both developers and organizations to unlock the full power of Formstack Forms.
This milestone release adds to the long-standing V2 API with a modernized version built for today’s development standards and tomorrow’s growth. The V2 API is not going away, so no need to worry about urgent migrations.
What’s New in the Forms 2025 API
The V2025 API introduces several key improvements that make it a major step forward for both developers and businesses:
- Personal Access Tokens (PATs)
Instead of relying on API keys inside Forms, the new API uses Personal Access Tokens managed within the Formstack Admin environment. This provides better security practices and a unified way to manage API credentials across Formstack products. - OpenAPI Specification Support
The API is fully OpenAPI-compliant, making it easier to get started and build faster. This also unlocks automated documentation, SDK generation, and compatibility with the developer tools you already use. - AI-Ready with LLMs.txt
The 2025 API includes an LLMs.txt file that enables AI assistants to help you build, test, and troubleshoot applications faster. Whether you’re using tools like Cursor or Claude, AI can now accelerate your development process. - Cleaner, More Consistent Service Structure
We’ve streamlined and rationalized the way services and data are structured. In V2, developers often ran into inconsistent data types or redundant endpoints. With V2025, responses are predictable and consistent, reducing guesswork and integration errors.
Why This Matters
In short: if you’ve been considering an integration but found the API too overwhelming in the past, now is the perfect time to start.
Built with Compliance in Mind
Like the V2 API, the Formstack Forms 2025 API supports the full range of Formstack compliance standards, including HIPAA, GDPR, SOC2, and PCI. Your data remains protected while you innovate.
