Currently when we go to a tool like TwoRavens, we send the API token in the URL. We needs these such tools to accept the token in the header, and for the dataverse side to send them in the header.
(From Backlog Grooming 1/31) When will make this change, we should support both for a while and then make the change to require it in the header instead of the URL. We should include these messages in the documentation.
