No event\nhandling, no bot conversation logic — just a tiny sender backed by a bot token.\n\n## Send\n\n- `GET ?text=hello`\n- `POST` with `{\"text\":\"hello\"}` (JSON), `text=hello` (form), or a raw text body\n\nEverything posts to the single channel set by `CHANNEL` at the top of `main.ts`.\n\n## Setup (~2 min)\n\n1. Open this val's HTTP endpoint and click **Create the Slack app** — the\n manifest (a bot user + `chat:write` + `channels:join`) is prefilled. Then\n **Install to Workspace**.\n2. Copy the **Bot User OAuth Token** (`xoxb-…`) into the `SLACK_BOT_TOKEN` env var.\n3. Set `CHANNEL` at the top of `main.ts` to your channel's ID — open the channel\n in Slack and grab the `C…` from the URL (or _View channel details_ → Channel\n ID, copy button at the bottom).\n4. _(Optional)_ Set `WEBHOOK_SECRET` to require `?key=…` on every call. Leave it\n blank to keep the endpoint open.\n\n## Notes\n\n- **Public** channels the bot isn't in are auto-joined on the first send.\n **Private** channels and DMs must invite it first (`/invite @webhook-pinger`).\n- The channel is hardcoded on purpose — a caller can't redirect the message\n somewhere it shouldn't go.\n- **Grow it:** this is a send-only base with room to climb. Add scopes to the\n `manifest` in `main.ts` and re-create the app to unlock threads (`thread_ts`),\n Block Kit attachments, reactions, multiple channels, or even inbound events.\n",[140],"pulls","branches","forks","envVars",{"_153":14,"_155":136},"connections",{"_153":62,"_154":62},"count","unfilledCount","emptyCount",{"_43":139,"_32":140,"_30":141,"_133":-5,"_41":42,"_40":142,"_134":58,"_38":162,"_13":62,"_33":20,"_35":144,"_24":25,"_137":-5,"_159":163,"_27":164},{"_43":132,"_32":28,"_30":31,"_133":-5,"_41":42,"_40":14,"_134":25,"_38":158,"_13":136,"_33":34,"_35":37,"_24":25,"_137":-5,"_159":160,"_27":161},["D",1782771610935],"children",[],[28],["D",1782762299045],[],[140],["D",1782762299045],{"_99":98,"_107":103},{"_99":98,"_100":101,"_102":103,"_18":55,"_104":105,"_106":25},{"_13":85,"_32":86,"_43":42,"_87":44,"_88":-5,"_89":-5,"_90":91,"_92":93,"_94":95,"_96":45,"_97":98},"ctx",{"_78":-5,"_127":202,"_203":204,"_205":206,"_207":25,"_208":25,"_209":25,"_210":58,"_211":-5,"_212":-7,"_213":-7,"_214":62,"_215":25,"_216":25,"_217":-5,"_218":25,"_219":25,"_220":25,"_221":-5},"ENV",{"_173":174,"_175":176,"_177":86,"_178":179,"_180":181,"_182":183,"_184":185,"_186":187,"_188":189,"_190":191,"_192":193,"_194":195,"_196":197,"_198":199,"_200":201},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","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"]
