OAuth
Authorize a client (OAuth 2.1 + PKCE)
Authorization endpoint for third-party and MCP clients. Presents/consumes the resource-owner authorization decision for the requesting client_id, validates the PKCE code_challenge (S256), and redirects back to the client’s redirect_uri with a single-use authorization code. High-level only — the underlying implementation also serves an interactive HTML consent flow for embedded WhatsApp signup and is not a general-purpose developer surface.
