Error "invalid_grant" while trying to get access token

[altruify_dev]

Getting the following error while make the call to get token. 

{

    "errors": [

        {

            "errorType": "invalid_grant",

            "message": "Authorization code invalid: <code> Visit https://dev.fitbit.com/docs/oauth2 for more information on the Fitbit Web API authorization process." }

    ],

    "success": false

}

I tried the CURL generated from "OAuth 2.0 tutorial page". Previously it was working.

Hi @altruify_dev 

Are you using a recent authorization code, or the one that was previously working?

I generated a new code and requested for token. Previously it was working, I mean 2 weeks before.

Would you please private message me your complete token request which is failing and include all headers, parameters and their values?

It started working again, not sure what happened is. But now I just tried again and I got access token. Thank you very much for the support given.
