Refresh token error

Hi everyone!
I received an Access and Refresh token using the code.
When I try to refresh my tokens, I’ve got an error:

{“reason”:“Invalid request : Invalid refresh Token{refresh_token}”,“error”:“invalid_request”} (Invalid refresh Token{refresh_token} without spaces)

What is the problem?

Hi Max,

Can you share the curl command that you used when trying to get the refresh token?

Hi Ojus,
curl -X POST
-H ‘Authorization: Basic X0***VDYTJH’
-H ‘Content-Type: application/x-www-form-urlencoded’
-d ‘grant_type=refresh_token&refresh_token=eyJ***9.eyJ***g’

Do you have any ideas?

Is anybody here?:face_with_monocle:

@Max thanks for pointing it out. We have fixed the typo since


Hi @ojus.zoom!
The problem has not been solved.

{“reason”:“Invalid request : Invalid refresh Token{refresh _token}”,“error”:“invalid_request”}

@ojus.zoom I’ve been getting this issue periodically as well. Our users are having to reauthorize too frequently due to this error response happening inconsistently. I know it’s not the code because 99% of the time it works fine. Is there a reason that tokens have to expire after 60 minutes? I work with API’s that handle financial information that last 24 hours, but to deal with a webinar or meeting it’s every hour? What is the rationale for such short time periods?
