Invalid redirect URI error

[Erik D]

We are working on integration our application and using SMART on FHIR to launch our application. We have issues when trying to redirect from a launch from the Developer Portal, we can clearly see that our launch works and we are prompted with our loading screen but when redirecting we get the Error Code: urn:cerner:error:authorization-server:oauth2:grant:invalid-redirect-uri. 

The issue persists in both the DSTU2 and R4 environment.

We have tried to Create a new application within the same account. Create a new account and then a new application on the new account. Still the same error persists.

We did manage to get the tutorial to work (https://engineering.cerner.com/smart-on-fhir-tutorial/) and tried changing the urls, and then switched them back to the original urls and we are getting the same error there now as well. 

Any help would be appreciated.

• Issue Summary:Unable to redirect. Error Code: urn:cerner:error:authorization-server:oauth2:grant:invalid-redirect-uri.
  What we have tried so far: Create a new application within the same account. Create a new account and then a new application on the new account.

Hello Erik,

                Good Morning. Based on our logs here's the issue :

"Client '1220c3ac-6654-4bdc-b85d-7a69e4124fbe' sent redirection URI [https://kc-careportal-dev.azurewebsites.net/Integration/], which didn't match any of the registered redirect URIs of [https://kc-careportal-dev.azurewebsites.net/Integration/CernerStart]" 

so in your call to authorize from your app, you will need to send in the correct redirect uri.

If the following is correct :

Launch URI : https://kc-careportal-dev.azurewebsites.net/Integration/CernerStart

Redirect URI : https://kc-careportal-dev.azurewebsites.net/Integration

then using code Console you will need to update your redirect URL to the above.

Let us know if you have any further questions.

Thanks,

Shriniket

Hello, we added 'redirect_uri': in our autorize call and the issue was resolved. However you launch url is actully CernerLaunch and our redirect url is CernerStart. But it is working now. Thank you.
