OAuth parameterized redirect

[nishanh]

I need to add a dynamic query parameter to the redirect url. However, this fails with a redirect url mismatch error. The domain and path are the same as the registered redirect, but I can't add any query parameters at runtime without getting a mismatch error. This doesn't seem to be an issue with google drive or MS OneDrive. Is there a way to pass state as a query param in the dropbox redirect url?

As a security feature, OAuth 2 redirect URIs must be pre-registered exactly. Wildcards and dynamic registration are not supported.

Instead, you can use the 'state' parameter to store variable information and receive it back when the user returns to your app:

Thank you. That parameter somehow eluded me when I was reading the docs.
