Facebook_mcb\n\nFacebook Graph API integration built on Val Town.\n\n## What it does\n\n- **Webhook receiver** — Verifies and receives real-time events from Facebook (page messages, lead ads, etc.)\n- **Graph API helpers** — Post to Pages, get page info, get recent posts, exchange tokens\n- **Live endpoint** — \n\n## Setup\n\n### 1. Create a Meta App\n\nGo to [developers.facebook.com/apps](https://developers.facebook.com/apps) and create a new app. Note the **App ID** and **App Secret** from App Settings → Basic.\n\n### 2. Set environment variables\n\n| Key | Description |\n|-----|-------------|\n| `FB_APP_ID` | Your Meta App ID |\n| `FB_APP_SECRET` | Your Meta App Secret |\n| `FB_PAGE_ACCESS_TOKEN` | Page Access Token (from Graph API Explorer or Page settings) |\n| `FB_VERIFY_TOKEN` | Any random string you choose (used for webhook verification) |\n\n👉 Add FB_APP_ID here: https://www.val.town/x/ziadamrme/Facebook_mcb/environment-variables?key=FB_APP_ID\n\n👉 Add FB_APP_SECRET here: https://www.val.town/x/ziadamrme/Facebook_mcb/environment-variables?key=FB_APP_SECRET\n\n👉 Add FB_PAGE_ACCESS_TOKEN here: https://www.val.town/x/ziadamrme/Facebook_mcb/environment-variables?key=FB_PAGE_ACCESS_TOKEN\n\n👉 Add FB_VERIFY_TOKEN here: https://www.val.town/x/ziadamrme/Facebook_mcb/environment-variables?key=FB_VERIFY_TOKEN\n\n### 3. 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",[],[194],["D",1785786973288],[],[18,66],["D",1785783426655],[181],[18],["D",1785783251243],{"_11":12,"_134":72},{"_11":12,"_129":130,"_71":72,"_31":70,"_131":132,"_133":30},{"_40":120,"_13":16,"_34":37,"_121":85,"_122":-5,"_123":-5,"_124":-5,"_125":-5,"_126":-5,"_127":14,"_128":12},"ctx",{"_54":-5,"_153":244,"_245":246,"_247":248,"_249":30,"_250":30,"_251":30,"_252":24,"_253":-5,"_254":-7,"_255":-7,"_256":26,"_257":30,"_258":30,"_259":-5,"_260":30,"_261":30,"_262":30,"_263":-5},"ENV",{"_215":216,"_217":218,"_219":16,"_220":221,"_222":223,"_224":225,"_226":227,"_228":229,"_230":231,"_232":233,"_234":235,"_236":237,"_238":239,"_240":241,"_242":243},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","71c1b20804b3232a7e513be260cfffc1932a9e97","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
