Encoding data to state parameter and decoding it

Naga Abhinaya T

Hi,

I am developing an app in dropbox using OAuth2.0 authorization flow. It involves redirection as well. I would like to store some data and retrieve data after redirection. As stated in documentation, 'state' parameter can be used to store data and get back the same. How can I store data and retrieve? what encoding algorithm is used? Please advise.

Any URL-safe encoding method should work. For example the Dropbox Java SDK uses a URL -safe version of base 64 encoding to store the CSRF token in the state parameter.
