Hi Dev Team,
We previously had the following scenario working we would make a call to the
https://cloud.feedly.com/v3/auth/token endpoint and provide our Access Token, client_id and client_secret and get a fresh token to retrieve data from Feedly for our internal development application.
But recently something changed and now instead of getting a new token we are now getting the following response:
HTTP/1.1 400
Date: Wed, 29 Sep 2021 17:13:13 GMT
Content-Type: application/json;charset=utf-8
Content-Length: 117
Connection: keep-alive
content-language: en-US
CF-Cache-Status: DYNAMIC
Server: cloudflare
CF-RAY: 6966d743aeb95c17-IAD
{"errorCode":400,"errorId":"ap15int-sv2.2021092910.793778","errorMessage":"public oauth clients must implement PKCE"}
We didn't used to have to deal with redirects and things before to get our tokens but now it appears to have changed. Can you provide some insight on what we can do to resolve this quickly as our app which is being used by many users is now down.
Thanks
