Refresh Token has Expired in Python

Attempting to send SMS with python SDK I keep getting "Refresh Token has Expired "

How do I set this to never expire in Python, is it even possible? The documentation does not say.

Hmm, well now Im getting
Exception: HTTP status code: 400

  "error" : "unauthorized_client",
  "error_description" : "Unauthorized for this grant type",
  "errors" : [ {
    "errorCode" : "OAU-251",
    "message" : "Unauthorized for this grant type"
  } ]
when I call rc.authorize('+NNNNNNN', '', 'password')
This is absurd I've done this with twilio send and receive in under 30mins...Not sure what the deal is but Im ready to cry uncle.

Tyler forgot to include
rc.authorize("Username", "password")
Sorry about that.

Yes, I shortened it to this as well as several other variations and no go? Any idea what its supposed to be? I got the above from ringcentrals own documentation?!? So either i'm reading it wrong, or they have another error. All this thing has to do is send an SMS.

r ='', {
Exception: HTTP status code: 404

  "errorCode" : "AGW-404",

Hi Rick,

There are several users reported "Refresh Token has Expired" and they are not using Python at all. So I wonder this might be an issue from RC server side.

Could you please do me a favor? Try my Python SDK:

By the way, there is a way to auto refresh the token:

If you still have the issue, please post the code to reproduce the issue. By then we can confirm it is a RC server side issue or not.

Phong thanks again! Umm that does not work either, it throws same exception. Is any of this written down, anywhere? I'm trying the following:
 and or
Does RC even work with python?

Hi Rick,

I don't use the Python SDK yet so I don't have exact code to show you. But I believe that after logged in, you can get the tokens info from the platform.auth().data(). When you need to refresh, just call platform.refresh() method.

Thanks for your assistance. How do I check the refresh token?

answered on Oct 9, 2018 at 8:48am  
After successfully authenticated/logged in, your refresh token with expire in 7 days. Every time your access token expires, you can use the refresh token to request for a new access token. And every time you request for a new access token, the new refresh token expiration time will be set to 7 days again.

If the refresh token also expired, you must direct the user to the login page to login again.

Can you double check if the refresh token really expires or it's because of some bug in the Python SDK?

In this case, if the refresh token really expired after 7 days, you may need to implement a timer to check the expiration periodically and send a request for new access token when it nearly expires. That way you can always have a valid refresh token.
