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.

We have added a few API services to help manage your Subaccounts in Formstack Forms!

https://developers.formstack.com/reference/subaccount

There are currently three key services to use:

1. GET /subaccount will return a list of all the subaccounts for a single parent account
2. POST /subaccount/:subaccount_id/theme/:theme_id/copy will copy a Theme from the parent account into a specific subaccount
3. POST /subaccount/:subaccount_id/form/:form_id/copy will copy a FORM from the parent account into a specific subaccount

These API services are available now in the V2API on Formstack Forms.

Welcome to the developer hub and documentation for Formstack!

We are introducing a new search endpoint that allows you to search all forms in an account for specific submission values.

GET /api/v2/submission
https://developers.formstack.com/reference/submission

The primary purpose of this API service is to support customers with GDPR data retention requests and similar. In the past, if an individual requested to be forgotten, searching each form for the submission data they provided (usually an email) was very time-consuming. This new service will allow searching for that attribute across all submission data in the account and provides a list of forms and submissions containing the value.

This service is limited to returning 10,000 submissions that match the search at any one time.
