We are applying tags tou our contacts via the API REST (https://developer.infusionsoft.com/docs/rest/#!/Contact/applyTagsToContactIdUsingPOST) but, from time ago, the API response is a 200 Ok status but in the body there is a notice of FAILURE. Do you know what kind of FAILURE could be? Is a InfusionSoft error or do we need take an action?
Thanks in advance
