Subscribe the webhook\n\nIn your Meta App dashboard, go to **Webhooks**, add the live endpoint URL above as the callback URL, and use the same `FB_VERIFY_TOKEN` you set as the env var.\n\n## API\n\n### `lib/facebook.ts` exports\n\n| Function | Description |\n|----------|-------------|\n| `graphGet(path, params)` | Generic Graph API GET request |\n| `graphPost(path, body)` | Generic Graph API POST request |\n| `postToPage(pageId, message)` | Post a text message to a Page's feed |\n| `postLinkToPage(pageId, link, message?)` | Post a link (with optional message) to a Page's feed |\n| `getPageInfo(pageId)` | Get Page info (name, fans, about, etc.) |\n| `getPagePosts(pageId, limit?)` | Get recent posts from a Page |\n| `getLongLivedToken(appId, appSecret, shortToken)` | Exchange a short-lived token for a long-lived one |\n\n## Files\n\n```\nmain.ts — HTTP endpoint (webhook verification + event receiver)\nlib/facebook.ts — Graph API helper functions\n```\n",[],[206],["D",1788788065740],[],[169,65],"2b71f77f-7061-44f8-b504-535a410a942e","facebook.ts","01a07c13-0c2d-7032-880a-40cfc77390df",6,["D",1788788087646],"// Facebook Graph API helper functions\n// Docs: https://developers.facebook.com/docs/graph-api\nimport { getActivePageToken } from \"./oauth.ts\";\n\nconst GRAPH_API_BASE = \"https://graph.facebook.com/v21.0\";\n\n/** Get the page access token: prefer the never-expiring one saved by the OAuth flow, else fall back to the env var. */\nasync function getToken(): Promise {\n const stored = await getActivePageToken();\n if (stored) return stored;\n\n const token = Deno.env.get(\"FB_PAGE_ACCESS_TOKEN\");\n if (!token || token === \"placeholder_token\") {\n throw new Error(\n \"No page token available.
