Reddit OAuth 2.0 Authorization
Reddit's OAuth 2.0 authorization system provides authentication for all Reddit API access. Developers register applications at reddit.com/prefs/apps to obtain client credentials. Supported grant types include authorization_code (for user-delegated access), client_credentials (for app-only access), and implicit (for installed apps). Access tokens are obtained from https://www.reddit.com/api/v1/access_token and must be refreshed using refresh tokens. All scopes and permissions are listed at https://www.reddit.com/api/v1/scopes.
