OAuth 2.0 Flow Sandbox — Step Through Authorization Grants Visually

Step through an OAuth 2.0 authorization flow interactively — the redirect to the authorization server, the authorization code exchange, the token response — with every step made visible, useful for debugging why a real OAuth integration is failing at a specific step, or for genuinely understanding the flow before implementing it.

How to use OAuth 2.0 Flow Sandbox

1. Choose a grant type (authorization code, client credentials).
2. Step through each stage of the flow.
3. See the actual requests, redirects and tokens at each step.
4. Compare against where your real integration is failing.

Frequently asked questions

Which OAuth grant types does it cover?

The authorization code grant (the standard flow for web apps) and other common grant types, showing the actual sequence of redirects and token exchanges for each.

Can this help debug a real OAuth integration?

Yes — stepping through the expected flow side by side with where your actual integration breaks is often the fastest way to spot a missing redirect URI, wrong grant type or misconfigured scope.

Does it explain the difference between an access token and refresh token?

Yes — the sandbox shows where each token type is issued and how a refresh token is used to obtain a new access token without re-prompting the user.
