How do I refresh a token

- My first access token get expired, now I want a new token without any User interface.

curl -X POST -u "{key}:{secret}" -d 
grant_type=refresh_token -d refresh_token={refresh_token}

but getting, below error

{"error_description": "Invalid refresh_token", "error": "invalid_request"}


Questions :

 1. What parameter should we pass to refresh_token? we need a new access token then why need this field?


I tried, expired token and new  access token(created using UI) as well but it not worked


Please help me to understand what parameter should we pass to the refresh_token

And how can I generate new token using terminal/curl

Hi Arun,

When you generated your very first access token with a command like

curl -X POST -u "{key}:{secret}" -d grant_type=authorization_code -d code={code}

the output should have been like this:

"access_token" : 5cEig-w1wXrlbM876XY1Nu-w5WfObqP0EOYo2JOPzs615QxZTqI9z8Gsy_21yX23Uspwblt8eKeBAcwpCrHY=,
"scopes": "repository",
"expires_in" : 7200,
"refresh_token" : 4Etiw6UP808AU3rIoUW,
"token_type" : bearer

You need to use the value of the field 'refresh_token' above in your call.

Afterwards, when you execute the following command with this value for the refresh token

curl -X POST -u "{key}:{secret}" -d grant_type=refresh_token -d refresh_token={refresh_token}

you will get in the output a new authorization code, and a new refresh token which you can use after the 2 hours expiry, and so on.

Please feel free to let me know if you have any questions.

Kind regards,

Hi Theodora

Thanks for quick response.

curl -X POST -u "{key}:{secret}" -d grant_type=authorization_code -d code={code}

 When we are using the {code}, parameter do we have any expiry for it? Because it seems get invalid once get used.

{"error_description": "The specified code is not valid.", "error": "invalid_grant"}

Hi Arun,

The following command

curl -X POST -u "{key}:{secret}" -d grant_type=authorization_code -d code={code}

you only use it once, in the beginning.

After the first time you use it, you execute the other command:

curl -X POST -u "{key}:{secret}" -d grant_type=refresh_token -d refresh_token={refresh_token}

After the 2 hours expiry, you also use

curl -X POST -u "{key}:{secret}" -d grant_type=refresh_token -d refresh_token={refresh_token}

This will give you both an authorization code and a refresh token to use the next time you execute it.

Does this help?

Kind regards,

It Help me lot.

Thanks Theodora

Like Theodora Boudale likes this

when executing 

curl -X POST -u "{key}:{secret}" -d grant_type=authorization_code -d code={code}


{"error": "invalid_grant", "error_description": "The specified code is not valid."}


what's the problem then?
