\n\n## Set up\n\n1. Remix this val\n2. [Get a Slack webhook](https://docs.val.town/integrations/slack/send-messages-to-slack/#1-create-a-slack-app--webhook)\n & set it as `SLACK_WEBHOOK_URL` in this val's Environment variables in the\n left sidebar\n3. [Get an Attio Access Token](https://app.attio.com/_/settings/developers/access-tokens)\n (with all read & write permissions) & set it as `ATTIO_API_KEY` in this val's\n Environment variables in the left sidebar\n4. Go to [`setup.ts`](./setup.ts) and click run to set up the events database\n and Attio webhook\n5. Go trigger some Attio events and see the message in Slack!\n\n## Files\n\n- [`attio/hydrate.ts`](./attio/hydrate.ts) - Converts raw webhook events into\n human-readable descriptions\n- [`attio/webhook.ts`](./attio/webhook.ts) - Attio webhook management and secret\n handling\n- [`attio/webhook-payload-types.ts`](./attio/webhook-payload-types.ts) -\n Complete TypeScript types for all Attio webhook events\n- [`alert.ts`](./alert.ts) - Cron job that processes recent events and sends\n Slack summaries\n- [`auth.ts`](./auth.ts) - Webhook signature verification middleware\n- [`openai.ts`](./openai.ts) - AI-powered event summarization using OpenAI\n- [`scratch.ts`](./scratch.ts) - Development scratchpad for testing functions\n- [`setup.ts`](./setup.ts) - One-time setup script to initialize database and\n Attio webhook\n- [`slack.ts`](./slack.ts) - Utility to send messages to Slack via webhook\n- [`sqlite.ts`](./sqlite.ts) - Database operations for storing and retrieving\n Attio events\n- [`webhook.ts`](./webhook.ts) - HTTP endpoint that receives webhooks from Attio\n\n## Attio webhooks\n\nAttio webhooks return thin events, which contain a bunch of IDs, but no\nhuman-readable data, such as:\n\n```json\n{\n event_type: \"record.merged\",\n id: {\n workspace_id: \"b6c564a6-2cf7-49ab-9320-dea013196bd7\",\n object_id: \"a87cf74e-5ca1-4a8d-b8d3-fcca5413d4c3\",\n record_id: \"d64ff9f2-d1f1-424c-8be6-e41129e35697\"\n },\n duplicate_object_id: \"a87cf74e-5ca1-4a8d-b8d3-fcca5413d4c3\",\n duplicate_record_id: \"112b5c78-1ffe-457a-8366-181b482888b4\",\n actor: { type: \"system\", id: null }\n }\n```\n\nThe trickiest part of this val was hydrating these events into human readable\nform, like \"Steve commented on OpenAI: they're using Val Town!\"\n\nAfter trying and failing (for hours!) to get LLMs to write this code for me, I\neventually bit the bullet and wrote it by hand. I only handled some of the more\ncommon event types, and left myself comments of other example events of types I\nhaven't handled yet.\n\nIn theory, Attio has a better way to handle this, analgous to\n[Stripe's method\nto fetch data for thin events](https://docs.stripe.com/event-destinations#fetch-data),\nbut I wasn't able to find it. If you figure it out, please send me a pull\nrequest or let me know at
