User Identification

​

Understanding Identified vs Unidentified Users

In Formbricks, understanding the difference between identified and unidentified users is crucial for effective survey segmentation and targeted feedback collection.

​

Identified Users

Identified users are those for whom specific information has been set, notably the userId. This identification allows for more precise targeting of surveys and a deeper understanding of the feedback provided. When enabled, all information specified by you and all actions are sent to Formbricks.

This method is recommended for applications where users are required to log in and will often return.

​

Setting User ID

To enable user identification, call the setUserId function of Formbricks and pass the user id. The user will show up in the Formbricks dashboard. Use a unique string, like a database ID or a unique email address. You can also anonymize the identifier, as long as it is unique for each user.

formbricks.setUserId("<user-id>");

​

Setting Custom User Attributes

Use the setAttribute function to set custom attributes for the user (e.g., name, plan).

formbricks.setAttribute("Plan", "free");

The setAttribute function works like this:

formbricks.setAttribute("attribute_key", "attribute_value");

You can also set multiple attributes at once by passing an object to the setAttributes function:

formbricks.setAttributes({
  attribute_key_1: "attribute_value_1",
  attribute_key_2: "attribute_value_2",
});

​

Logging Out Users

When a user logs out of your webpage, also log them out of Formbricks to prevent activity from being linked to the wrong user. Use the logout function:

formbricks.logout();
