1. Re: Error trying to update contact using ContactList_UpdateInsert
Alex Pavelescu May 21, 2014 7:59 AM (in response to Chris Jessen)Hi,
If you are updating a CRM entity that doesn't have External ID you can't do it while also providing a username.
What you need to do is create a backup of your usernames, update the entity's external ID through the API call (it will wipe the username since the respective entry is empty) then re-make the call with the username in place. It will update that field only then.
Kind Regards
Alex
