We are working through the API to apply tags and remove tags to an existing contact record. We have a Higher Logic integration where they pull updates about a contact record based on the last_updated field on the Contact record. When I remove a tag from a contact through the API, how can I also update the Contact record’s last_updated date so that HL can pick up our tag changes?
You don’t have any way to directly affect the last updated field. However, at this point, a tag application now counts as an update to the contact. Otherwise, you can create a custom field that you merely modify to trigger the system to set the last updated field.
