API oauth code/token storage php

[FSUInnovation]

What array variable get returned to following the redirect uri upon a successful oauth2 flow on my app? Is it stored in a variable like $_GET['code'] or something like that? I tried checking for it in a variable and I recieved a error that the variable did not exist.

You can find examples of the information included on the redirect URI after the user authorizes the app in the /oauth2/authorize documentation, under the "Returns" section:

https://www.dropbox.com/developers/documentation/http/documentation#oauth2-authorize

Specifically, there is a "Sample response" for both the code and token flow.

Note that for the code flow, the values are passed as URL parameters, so they do get sent to your server. Exactly how the URL parameters are made available to your will depend on the web framework you're using, so I can't offer detailed insight on that. I recommend referring to the documentation for your web framework.

For the token flow, they are passed on the URL fragment, and so do not get sent to your server.

I use php with an apache and mysql server. I don't have any framework like laravel that I use.

In that case I recommend checking the documentation for how to access the URL parameters for the URL from Apache in PHP. Those aren't made by Dropbox so unfortunately I can't provide specific guidance for that. (It sounds like you're making a web app though so do make sure you are using you're using the "code" flow and not the "token" flow.)
