Was this just a drop-in from their OpenAPI spec file or you had to copy and paste this in?

@shazron

This was a copy and paste, I originally did a full copy but there were a lot more changes than I expected, including some changes to existing paths (may have been breaking changes?). Should we create a follow-up task to sync with the latest?

[shazron]

@MichaelGoberling we've been doing patches for one-off additions: https://github.com/adobe/aio-lib-console/tree/master/spec/patch - this is so we can just drop-in any new Transporter specs. But now that you mentioned that there are other breaking changes, not sure

@shazron

Ah, I see. I think the patch is needed for that one xr endpoint because it isn't in the Swagger definition. The endpoint I added as part of this PR is part of the Swagger, I just decided to forgo doing the full drop-in because it included more changes than I expected. Let me try to do the full drop-in and do some testing on this PR

Edit: Okay, just pushed a change doing the full drop-in. I updated any endpoints we currently support in index.js and left any new endpoints alone. The endpoints that had path changes were not in index.js, so I think we're good there
