Instagram / Meta OAuth Callback Endpoint

Instagram Authorization Callback

Instagram / Meta OAuth コールバックエンドポイント

Project: BANSHO ENGINE（万象機関） Platform: Meta for Developers / Instagram Type: OAuth Redirect Endpoint (Planned)

Important: This URL is reserved for future use pending Meta App Review approval. The Instagram integration is not yet active. This page is provided to satisfy the Meta App Review requirement for a registered redirect URI.

No tokens or secrets are displayed on this page. This is a static explanation page only. No authorization codes, access tokens, or user credentials are processed or shown here. No public user action is required on this page.

Planned Redirect URI

https://banshoengine.com/auth/instagram/callback

This URL is routed to: auth-instagram-callback.html (via .htaccess RewriteRule)

01

Purpose of This URL

This URL (https://banshoengine.com/auth/instagram/callback) is reserved as the planned OAuth redirect endpoint for Meta / Instagram Login integration in BANSHO ENGINE.

When (and if) Meta App Review approval is received, and the authorized owner completes the Instagram authorization flow, Meta will redirect the browser to this URL with an authorization code. The actual authorization processing (exchanging the code for an access token) will be handled by the secure backend or local automation environment, not by this static public page.

This is a static explanation page. The Instagram integration is not yet active. This URL is registered in advance as required for the Meta App Review submission process. No actual OAuth processing occurs on this static website. All token handling will occur in the owner's private, non-public operation environment.

02

How the Planned OAuth Callback Will Work

  • After Meta App Review approval (and only then), Meta will redirect the owner's browser to this URI after the authorization consent flow.
  • The authorization code provided by Meta will be handled by the owner's secure backend environment. It will not be displayed to any public user or logged on this static page.
  • No access tokens will be stored on or transmitted through this static page. All token handling will occur in the owner's private, non-public environment.
  • No public user action is required on this page. This URL exists solely as the registered redirect target for the planned Meta / Instagram OAuth flow.
03

Security Assurances

  • No client secrets appear on this page or any public page of this website.
  • No access tokens or refresh tokens are displayed or stored in public HTML or JavaScript.
  • No user credentials or personal information are requested or processed on this static page.
  • This page does not perform any API calls or external network requests.
  • The Instagram integration will only be activated after Meta App Review approval is fully confirmed.
