OAuth2 Redirect Url

OAuth2 Redirect Url

IQCloud
Explorer | Level 3

Hello there,

 

For the Oauth2 bewlow

https://api.dropbox.com/1/oauth2/authorize?response_type=code&client_id=zzzzzzzzzzz&redirect_uri=htt...

 

It is saying ClientId is invalid. 

The app has the same redirect url: https://localhost:44332/Login?Cloud=DROP&ClientId=393903

 

Could you please advise wether it is possible to add extra parameters and only the first one is accepted (Cloud) so far.

 

Error is:

More details for developers

unknown field "ClientId"

 

Please let me know!

 

Thanks

It sounds like you're not URL encoding the 'redirect_uri' value, and so the URL parameters on your redirect URI are being sent as actual URL parameters to the Dropbox /oauth2/authorize app authorization page itself, which does not expect those parameters.

 

You'll need to URL encode your 'redirect_uri' value. For example, for the sample you included here, that would be:

 

https%3A%2F%2Flocalhost%3A44332%2FLogin%3FCloud%3DDROP%26ClientId%3D393903

 

Also, note that per the documentation, the app authorization page should be accessed at https://www.dropbox.com/oauth2/authorize (not on api.dropbox.com).
