Here, you'll find help with common issues.

Troubleshooting

 Formbricks provides two APIs: the Public Client API for frontend survey interactions and the Management API for backend management tasks.

REST API

Here is how you can generate an API key which gives you full access to the Formbricks Management API. Keep it safe!

Generate API Key

Here is how you can test your API key to make sure it is working.

Test API Key

Update a contact's attributes in Formbricks to keep them in sync with your app or when you want to set a custom attribute in Formbricks.

Update Contact (Attributes)

Retrieves a contact's state including their segments, displays, responses and other tracking information. If the contact doesn't exist, it will be created.

Get Contact State

Create a new display for a valid survey ID. If a userId is passed, the display is linked to the user.

Create Display

Update an Display for a user. A use case can be when a user submits a response & you want to link it to an existing display.

Update Display

Retrieves the environment state to be used in Formbricks SDKs **Cache Behavior**: This endpoint uses server-side caching with a **5-minute TTL (Time To Live)**. Any changes to surveys, action classes, project settings, or other environment data will take up to 5 minutes to reflect in the API response. This caching is implemented to improve performance for high-frequency SDK requests.

Get Environment State

Create a response for a survey and it's fields with the user's responses. The userId & meta here is optional

Create Response

Update an existing response for example when you want to mark a response as finished or you want to change an existing response's value.

Update Response

Endpoint for creating or identifying a user within the specified environment. If the user already exists, this will identify them and potentially update user attributes. If they don't exist, it will create a new user.

Upload Public File

Management API endpoint for uploading public files to local storage. This endpoint requires authentication. File metadata is provided via headers (X-File-Type, X-File-Name, X-Environment-ID, X-Signature, X-UUID, X-Timestamp) and the file is provided as a multipart/form-data file field named "file". The "Content-Type" header must be set to a valid MIME type.

Upload Public File to Local Storage
