[SOLVED] Skype Bot OAuth error that wasn't happening before

Skype Bot OAuth error that wasn't happening before

I previously had a Skype bot able to post messages using the API.

But on 11/17/17 I started getting this error on every attempt, and as a result, no message gets posted. I haven't changed anything.

requests.exceptions.HTTPError: 401 Client Error: The provided 'OAuth' ticket failed authentication. for url: https://apis.skype.com/v2/conversations/[conversation]/activities/

The process I use is to get an access token witha post to https://login.microsoftonline.com/common/oauth2/v2.0/token and then to use that token to post a message to https://apis.skype.com/v2/conversations/[conversation]/activities/

It's able to get the token fine, but then when the message post is called, it raises the above exception.

Solution

I've faced with exactly the same problem and this worked for me:

I left all send messages endpoint as is for v2, BUT in token generation POST payload I've changed 'scope' -> 'https://api.botframework.com/.default'
