}
oauth.soundcloud.start/oauth/soundcloud/startPOSTauth:webExpected payload:

"provider_app_id": 1,
"target_owner_type": "system",
"target_owner_id": null
}
oauth.soundcloud.callback/oauth/soundcloud/callbackGETauth:webReceives provider callback values (state, code, error, error_description).
oauth.microsoft_todo.start/oauth/microsoft-todo/startPOSTauth:webStarts the Microsoft OAuth flow for the currently logged-in user.
oauth.microsoft_todo.callback/oauth/microsoft-todo/callbackGETauth:webReceives provider callback values (state, code, error, error_description) and stores the per-user Microsoft To Do connection.
For Slack app configuration, use:
https://tools.tornevall.com/oauth/slack/callbackhttps://tools.tornevall.net/oauth/slack/callbackIf SLACK_REDIRECT_URI is configured, that value is used as the effective redirect URI and should be registered in Slack App settings.
For Microsoft To Do / Microsoft Graph app configuration, register the callback matching the current environment:
https://tools.tornevall.com/oauth/microsoft-todo/callbackhttps://tools.tornevall.net/oauth/microsoft-todo/callbackIf MICROSOFT_TODO_REDIRECT_URI is configured, that value becomes the effective redirect URI and should be registered in the Microsoft Entra app as well.
When the Microsoft To Do platform app is not environment-managed, the shared app settings can now also be saved from /settings/integrations/microsoft-todo by an acknowledged admin. The page shows the same recommended callback URL together with additive diagnostics about missing platform-app fields.
