API v1.0.0

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

REST API

Update Response

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

Create Response

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

Update Display

Retrieves the environment state to be used in Formbricks SDKs

Get Environment State

Go to app

Support

Enhance your questions by adding images or videos. This makes instructions clearer and the survey more engaging.

Add Image / Video

Create complex survey logic with the Logic Editor. Use conditions, actions, and variables to create a personalized survey experience.

Conditional Logic

Overwrite the global styling theme for individual surveys to create unique styles for each survey.

Custom Styling

Add data to a submission without asking the user to type it in. This feature is especially useful when you already have information about a user that you want to use in the analysis of the survey results (e.g. `payment plan` or `email`).

Hidden Fields

Automatically close your survey after reaching a set number of responses in Formbricks. This is useful for limited offers, exclusive surveys, or when you need a specific sample size.

Limit Submissions

Create surveys that support multiple languages using translations. This helps you reach a diverse audience without making separate surveys for each language. It also simplifies survey creation, delivery, and analysis for multilingual audiences.

Multi-language Surveys

Capture and analyze partial submissions, providing detailed insights into how participants interact with each question within your survey. This feature is crucial for identifying specific points where respondents may disengage, allowing you to understand and address drop-offs effectively.

Partial Submissions

Personalize your surveys by dynamically inserting data from URL parameters or previous answers into questions and descriptions. The Recall Data feature helps create engaging, adaptive survey experiences tailored to each respondent.

Recall Data

Create public, shareable versions of your survey results dashboards. This feature enables you to easily share survey results with stakeholders, team members, or the public without granting access to your Formbricks account.

Shareable Dashboards

Optimize your survey management with custom Start & End Conditions in Formbricks. This feature allows you to control exactly when your survey is available for responses and when it should close, making it ideal for time-sensitive or number-of-response-limited surveys.

Schedule Start & End Dates

Formbricks captures metadata of your users for you when they fill a survey. This metadata is useful for understanding the context in which the user filled the survey. For example, if you are running a marketing campaign, you can understand which source is driving the most responses. Or if you are running a survey on a specific page, you can understand the user's behavior on that page.

User Metadata

Variables are a powerful feature in Formbricks that allows you to keep track of data variables when user fills a form. This feature is especially useful when you want to use your survey as a quiz.

Variables

Create your first link survey in under 5 minutes.

Quickstart

App surveys deliver 6–10x higher conversion rates compared to email surveys. If you are new to Formbricks, follow the steps in this guide to launch a survey in your web or mobile app (React Native) within 10–15 minutes.

Framework Guides

The Address question type allows respondents to input their address details, including multiple fields such as address lines, city, state, and country. You can configure the question by adding a title, an optional description, and toggling specific fields to be required.

Date
