Hi @shugufta 

Would you please provide the endpoint and headers that you're executing when getting the 401 error.   Please do not include any sensitive data like auth codes, tokens, client ids, secrets, etc.

Best,

Gordon

Hi Gordon,

Once I click the "https://www.fitbit.com/oauth2/authorize?response_type=code&client_id=clientID&redirect_uri=https://dev63919.service-now.com/oauth_redirect.do&scope=activity%20nutrition%20heartrate%20location%20nutrition%20profile%20settings%20sleep%20social%20weight"  link, it gives below error.

Your OAuth redirect failed. Please check if the redirect URL setup in your OAuth configuration matches your ServiceNow instance URL.

Also the response_type=code is not getting generated.

Kindly suggest on how we can get the code.

Thanks & Regards,

Shugufta.

Hi @shugufta 

Thank you.   Try specifying your redirect URL as "https%3A%2F%2Fdev63919.service-now.com%2Foauth_redirect.do"

Hi @Gordon-C 

This is the redirect URL https://dev63919.service-now.com/oauth_redirect.do

[Gordon-C]

In your code, please specify the redirect URL as https%3A%2F%2Fdev63919.service-now.com%2Foauth_redirect.do instead of https://dev63919.service-now.com/oauth_redirect.do

Even then I am redirected to same page. When I test getting below response

 {"success":false,"errors":[{"errorType":"invalid_token","message":"Access token invalid: null. Visit https://dev.fitbit.com/docs/oauth2 for more information on the Fitbit Web API authorization process."}]}

My main issue is it is not generating the code and giving me the response as below. I have given response_type=code here

{"errors":[{"errorType":"invalid_request","message":"Missing parameters: code Visit https://dev.fitbit.com/docs/oauth2 for more information on the Fitbit Web API authorization process."}],"success":false}

Hi @shugufta 

It seems you have several errors here, and we should address them one at a time.  I'm not sure if your first error not being resolved is resulting in the other errors being generated.

I believe the first problem is when executing https://www.fitbit.com/oauth2/authorize?response_type=code&client_id=clientID&redirect_uri=https://d... you receive the error 

Your OAuth redirect failed. Please check if the redirect URL setup in your OAuth configuration matches your ServiceNow instance URL.

I believe this is because your application need to specify the redirect URL as redirect URL as https%3A%2F%2Fdev63919.service-now.com%2Foauth_redirect.do instead ofhttps://dev63919.service-now.com/oauth_redirect.do.   However, the redirect URL in the dev.fitbit.com application configuration needs to be https://dev63919.service-now.com/oauth_redirect.do.

Once the user redirects back to your application, the redirect URL will have an authorization code.   

ex. https://www.exampleapp.com/callback?code=6ec38fd5d19a5a3f85a021f673e15ae04e9293#_=_

You need to swap out the code for the access token.

example

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

Authorization: Basic <basic_token>

clientId=<client_id>&grant_type=authorization_code&redirect_uri=https%3A%2F%2Fwww.exampleapp.com%2Fcallback"

&code=6ec38fd5d19a5a3f85a021f673e15ae04e9293

The response should provide you with the access_token.   The OAuth 2.0 Tutorial can walk you through this process using your application settings.  See https://dev.fitbit.com/build/reference/web-api/troubleshooting-guide/debugging-tools/#oauth-2-0-tuto....

If you're doing these steps as I've described, please provide the URL and error message that you're receiving.
