The Update Custom Property task can be used to change the value of a custom property within a site.

The custom property must be created in the site before the task runs. This can be done in Site Settings - Properties.

The task can then change the value of the property based on specified conditions.

A simple example of this would be to update a user custom property called “Membership” from a blank value to “Member” once a membership request has been submitted by the user, and approved by an administrator.

More complex examples can be accomplished with the additional use of sneq scripting.
