API ReferenceUser Properties

Update User Property

This API enables you to update user properties of your users listed in your User Profiles. If the user with distinct ID doesn’t exist, it creates a new user with the provided distinct ID and updates values for all the provided properties.

Note: If a property was not created earlier, it will create a new property and the data type of the property will be determined based on the data type of the value. For example, if you $set a new property called premium_user=true, it will create the premium_user property with Boolean type and value true.

The property values can take the following data types:

  • String: Can be alphanumeric and contain a maximum of 255 characters. Example: user_type=Premium or membership_number=ABC123.
  • Number: Can be an integer or a decimal. Example: ltv=23000 or cost=20.34.
  • Boolean: Can only contain true or false values.
  • Date: Must be in ISO 8601 format. Example: membership_date=2020-10-01T18:30:00.000Z or membership_date=2020-10-01T18:30:00Z or membership_date=2020-10-01T18:30:00.000+05:30 or membership_date=2020-10-01T18:30:00+02:00 or membership_date=2020-10-01.
  • List: Can contain an array of strings, numbers, and dates. Example: products_ordered=['iPhone 16 Pro', 'iPad 32 GB'] or purchase_amount=[23000, 20.34] or purchase_date=['2020-10-01T18:30:00Z', '2021-11-01T13:35:00+02:00', '2023-12-05']
If you try to set a value with a data type that does not match the predefined property type, the API will accept the request but ignore the invalid value. For example, if a predefined property cost expects a numeric value and you try to set it to ABC, the API will not store the value.

These user properties can be used to filter your users for creating user cohorts and campaigns.
