A contact can have any number of tags applied to them. The API enables you to add or remove a tag from a contact and see all the tags that have been applied to a specific contact.

The contactTags API endpoint is used to assign existing tags to existing contacts. If either the tag or the contact does not exist you must create them before trying to assign a tag to a contact. Refer to the links below for documentation on how to create contacts and tags.
