Formbricks offers two types of APIs: the Public Client API and the Management API. Each API serves a different purpose, has different authentication requirements, and provides access to different data and settings.

Public Client API

The Public Client API is used by our SDKs and doesn’t require authentication, making it ideal for client-side interactions without exposing sensitive data.

We currently have the following Client API methods exposed and below is their documentation attached in Postman:

  • Displays API - Mark a survey as displayed or link a display to a response for a person.

  • Contacts API - Update contact attributes.

  • Responses API - Create & Update a Response for a Survey.

Management API

The Management API gives full access to all data and settings available in your Formbricks account. It requires a personal API Key for authentication, which you can generate and manage in the Settings section of the Formbricks app.

We currently have the following Management API methods exposed and below is their documentation attached in Postman:
