Issue refreshing token

Hello,

 

we are receiving a few 400 error responses when we try to refresh a refresh token with body

error: invalid_grant
error_description: The provided authorization grant is invalid.

but it is happening only for a few refresh tokens.

 

Any ideas what could the issue be?

 

As it is not a general issue and we haven't been able replicate it yet, it is really hard to identify what is happening. 

 

Thanks!

@billSx  Can you tell us exactly what you're trying to accomplish with this?

 

Did the same method work until just recently?

Hi @AshC ,

 

we are using the GoToTraining in order to create training sessions but when the access token expires, we use the refresh token to create a new pair of access and refresh tokens.

 

There are a few cases in which we get this error but we don't see any diff.

 

The request we do is something like that:

https://api.getgo.com/oauth/v2/token?grant_type=refresh_token&refresh_token=XXX
