I have an app that has been working for two-way contacts' sync for quite sometime. Nothing has changed on my end.
Now, any PUT request is getting a 401 "token_rejected" error while all the GET requests continue to work fine. Both are using HTTPS.
Any ideas on what the problem may be?
I double checked, and my contact permissions are read/write, and I tried requesting a new key & secret.
If I switch to using a Authorization header it gives: unable_to_determine_oauth_type
But otherwise it works identically. GETs work perfectly, PUTs all fail. This app has been up and running for about 2 years without issue.
