400 Bad Request: Invalid refresh token

Hi,
Since I migrated TaskUnifier to API v3, many users are facing this error when the app is trying the refresh the token. I don't know how to debug this as I simply send the request and receive an HTTP 400 exception. Is there any way at your side to debug this ? Thanks, Ben |

If the refresh token becomes invalid, your app should prompt the user to sign in again to get a new one. One thing to note is that each time you use a refresh token to get an access token is that you get both an access token and a new refresh token in return. You should discard the old refresh token and use the new one. This may help with your error. I will also investigate what the issue might be.

Hi,
That's what I do. The first thing I do is trying the retrieve the account info, if it fails do to an invalid token, I try to refresh the token. If it fails (BadRequest), I ask a new auth code. If it works, I retrieve the account info with the new token and I replace the existing token and refresh token with the new ones. This refresh of the token works 80% of the time. But some users are often receiving a BadRequest: Invalid refresh token error, that I can't understand. The latest refresh token I received is sent in the request, so I don't have much ways to debug this. Thanks, Ben |

Another developer is also having this problem, but we have not been able to yet confirm what the problem is. There are many apps that work correctly so I suspect that the problem is with the OAuth library that you are using. Are you using the Google OAuth library perhaps?

Hi,
I'm using my owner library. I checked that the auth code and refresh token which are sent are always to latest I received from Toodledo. What I don't understand is that it is working for most of my users, but not for some of them. If I had more information in the error message I could maybe debug this more easily. It would be great if you could check why the error is returned. Is the refresh token missing somehow ? Is the refresh token invalid because out of date ? Is the refresh token invalid because it doesn't exist ? Is the refresh token invalid because it is an old one ? Thanks, Ben |

Can you please make a support ticket and include a log of your API calls including the refresh token you are trying to use? We can look it up and see what is happening to it.
