The Relicx SDK provides APIs that can be used to capture relevant application specific information along with the customer sessions. For application user specific information use the API. To set specific session specific variables use the API. You may also use the API to attach any custom labels to a session.
The special keys are automatically displayed in the relicx app and are also searchable within the app. If you want to find out sessions from a specific user it is a perfect use case for the identify() API.
In the image below, we see an example of user emails captured using the identify() API.
The following image shows an example of labels captured through sessionvars. These attributes are also inherited into Test Edit and Test Run Pages.
