OAuth redirect

[WORMSS]

Hello,
Let me prefix this with, the answer is "we cannot tell you this due to security" ... BUT
There is a app that my gym is basically forcing us to use. mywellness. They have a whole page about tying a bunch of other API services together. One of them being FitBit.
I suspect they have gone through a domain name change, or they have changed endpoints on their server. And have broken all their integrations. Again one of them being FitBit, so the return uri they are sending to the fitbit auth server is wrong.

I was hoping I could get the correct return_uri for the mywellness app. client_id 228YHF. 
I know this is usually stored in the developers portal for other oauth integrations I have built myself. 

The one they are trying to use is 

https://v1.mywellness.com/cloud/thirdpartiesactivity/fitbit/returnuri

 and it's reported as incorrect.
I just want to reconstruct the correct url so I can get things integrated properly.

This kinda sounds more of a Web API issue, unless they're using OAuth in an app that runs on a Fitbit smartwatch. Confirm?

oh god, I had too many tabs open when searching through your forum, I thought when I was making the post I was within the Web Api sub. Sorry, I'll recreate it there..

No worries; I could have moved the topic for you!
