Enrich new user data with a webhook and post results to Slack

• Your application sends a request to this webhook with a user's email address.
• This webhook uses the Val Town Clay Proxy to enrich the user data with information like their LinkedIn profile, company name, company size, funding state, total funding, and more.
• The data is passed to Chat GPT for lead scoring
• The results are sent to your own Slack webhook

1. Remix this val
2. Create a custom Slack app with an incoming webhook and add its URL as SLACK_WEBHOOK_URL. See the docs for Sending Slack messages for more info.
3. Use webhook.test.ts to test that your enrichment works. You should see a message in your Slack channel.
4. In your own application, add logic to send a request to this webhook when new users sign up.

This val uses Clay under the hood to provide user-enrichment data. The Val Town Clay Proxy is only available to paying Val Town Team accounts. To sign up to use this val, please send an email to mailto:enrichment@val.town.

To make this more secure, you can optionally set a WEBHOOK_SECRET environment variable and only accept requests that use the secret when posting.

Create val
// Add this to `main.ts` to only accept requests that include the secret
const secret = req.headers.get("Authorization");
if (secret !== `Bearer ${Deno.env.get("WEBHOOK_SECRET")}`) {
  return new Response("Unauthorized", {
    status: 401,
  });
}
