Note

This pull request is marked as draft because the current implementation of the authorizeURL, accessToken, and userInfo options only accepts endpoint URLs for the OAuth 2.0 Authorization Code flow. At the moment, it is not possible to pass additional parameters or custom headers to these endpoints.

The Dropbox API, specifically for retrieving the current account, requires the use of the POST HTTP method instead of the commonly used GET method. These requirements are not currently supported by Aura Auth’s default OAuth flow.

This OAuth provider faces the same limitation as the drafted Twitch OAuth provider (Twitch OAuth Provider – #47) and the (Notion OAuth provider #49), as both require support for custom headers and non-default request configurations in OAuth endpoints. Once this capability is introduced, this pull request can be completed and reviewed properly.
