UniFi stock alerts in Discord.

In your server: Server Settings, then Integrations, then Webhooks, then New Webhook. Pick the channel restocks should land in and copy the webhook URL. Treat it like a secret; anyone holding it can post to the channel.

Create a Cloudflare Worker (the free tier is more than enough) with this code, then set two secrets: DISCORD_WEBHOOK_URL from step 1 and NOTIFI_TOKEN, a long random string of your choosing.

export default {
  async fetch(request, env) {
    if (request.method !== "POST") return new Response(null, { status: 405 });
    // The bearer token you set in NotiFi; rejects anyone else's posts.
    if (request.headers.get("Authorization") !== `Bearer ${env.NOTIFI_TOKEN}`) {
      return new Response(null, { status: 401 });
    }
    const alert = await request.json();
    if (alert.event !== "in_stock") return new Response(null, { status: 200 });

    const price =
      alert.price?.amount != null
        ? ` at $${(alert.price.amount / 100).toFixed(2)}`
        : "";
    await fetch(env.DISCORD_WEBHOOK_URL, {
      method: "POST",
      headers: { "Content-Type": "application/json" },
      body: JSON.stringify({
        content: `**${alert.product.title}** is back in stock${price}\n${alert.product.url}`,
      }),
    });
    return new Response(null, { status: 200 });
  },
};

In NotiFi: Settings, then Webhook. Paste your Worker's URL and set the same bearer token as NOTIFI_TOKEN. Hit Test to see a sample message land in the channel. From then on, every restock alert for your watched products posts to Discord the moment it fires. The full payload shape is in the webhook documentation.
