oauth 2.0 callback url issue

[Pramod]

Hi there,

I am having issue with my callback url. I have mentioned the same URL in fitbit app and for my application.

Here is the code snippet...

return this.oauth2.getAuthorizeUrl({

        response_type : 'code',

        scope : 'heartrate',

        redirect_uri : 'https://example.com/gettoken'

});

But it always gives me error after user authentication on Fitbit.

LOG:

{"statusCode":400,"data":"{"errors":[{"errorType":"oauth","fieldName":"redirect_uri","message":"Redirect_uri mismatch: null"}],"success":false}"}

I am unable to figure out the issue. Please help.

Thanks

Does your redirect_uri value match a URI specified in your app settings on https://dev.fitbit.com ?

Hi Jeremiah,

I have cross checked it several times and for sure i have exactly same vaules for redirect_uri and URI specified in my app settings.

Currently having the same problem. The uri is the same (even copy pasted to make sure)

Hi TEvashkevich,

Did you find the solution?

It is getting tough for me and I really need multiple callback URL for the App, but it is not working for the single one.

If i leave the redirect_uri parameter, it works fine. Is it same in your case?

[TEvashkevich]

I haven't found a solution yet no. 

By leaving do you mean not having it in? Just leaving that part empty?  I by all means will give it a try

If you do not pass the redirect_uri parameter, you will get the access_token after fitbit auth.

see the difference

With uri parameter:

https://api.fitbit.com/oauth2/authorize?response_type=code&scope=heartrate&redirect_uri=https%3A%2F%...

Without uri parameter

https://api.fitbit.com/oauth2/authorize?response_type=code&scope=heartrate&client_id=xxxxxxxx

Hope it will help you.

 Ah, I was getting the redirect_uri Mismatch in the Authorization step, where we have to POST to 

https://api.fitbit.com/oauth2/token

What was the solution here?

[TEvashkevich]

For the setup of the general OAuth2 stuff (Disregard the Unity Plugin I suggested here as it is not allowed anymore and I described how to do it without the plugin in the other post I link below.)

To change to native (which is needed now)

redirect_uri should like "http://example.com/auth"

instead of "http%3A%2F%2Fexample.com%2Fauth"

For me including redirect_uri param in the " .../oauth2/token " request solved the problem. Strange it would be required here since it is useless in a server side token request.
