JohnP - thanks for your question. As for your OAuth2 question - yes, you would think eh? But you’re not at fault.
Our product team didn’t think their processes through when they uploaded their OAuth2 documentation in their eagerness to launch. They didn’t consider how you were suppose to obtain the new client ID and secret - which is currently not self-service and not associated with developer.concur.com Sandbox’s.
So bottom line - if you’re a partner application developer and wish to develop an application for the App Center, let us know and we’ll order up an application client ID and secret for your Sandbox. If you are developing an application for a TMC - also let us know but you’ll need to stick to the original OAuth.
Original OAuth documentation - which you can refer to and use - is available here:
