User properties are attributes you can set on a user level. You can send user properties to third party platforms as well as use them in Qonversion for customer segmentation and analytics.
Here is an example of user properties:

Usage

There are two types of user properties: Qonversion defined user properties and custom user properties.

Defined User Properties

We defined some common case properties and provided API for adding them:

Qonversion.setProperty(.email, value: "[email protected]")

[Qonversion setProperty:QNPropertyEmail value:@"[email protected]"];

Qonversion.setProperty(QUserProperties.Email, "[email protected]");

Qonversion.setProperty(QUserProperties.Email, "[email protected]")

Qonversion.setProperty(QUserProperty.email, '[email protected]');

Qonversion.setProperty(Property.EMAIL, '[email protected]');

Qonversion.SetProperty(UserProperty.Email, "[email protected]");

The full list of the defined properties is provided below:

Qonversion.setUserProperty("liked-app", value: "yes")

[Qonversion setUserProperty: @"liked-app", value: @"yes"];

Qonversion.setUserProperty("liked-app", "yes");

Qonversion.setUserProperty("liked-app", "yes")

Qonversion.setUserProperty('liked-app', 'yes');

Qonversion.setUserProperty('liked-app', 'yes');

Qonversion.SetUserProperty("liked-app", "yes");
