Supabase - Squasher

Edge Functions via OpenTelemetry

Supabase Edge Functions support Deno and run on the edge. Use the HTTP API to report errors:

// supabase/functions/my-function/index.ts
import { serve } from "https://deno.land/[email protected]/http/server.ts";

const SQUASHER_URL = `https://ingest.squasher.ai/v1/ingest/${Deno.env.get("SQUASHER_PROJECT_ID")}`;
const SQUASHER_KEY = Deno.env.get("SQUASHER_API_KEY")!;

serve(async (req) => {
  try {
    const result = await handleRequest(req);
    return new Response(JSON.stringify(result), { status: 200 });
  } catch (error) {
    // Report to Squasher
    await fetch(SQUASHER_URL, {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
        "x-squasher-key": SQUASHER_KEY,
      },
      body: JSON.stringify({
        message: error instanceof Error ? error.message : String(error),
        type: error instanceof Error ? error.constructor.name : "Error",
        level: "error",
        stack: error instanceof Error ? error.stack : undefined,
        tags: { function: "my-function", url: req.url },
      }),
    });

    return new Response("Internal Server Error", { status: 500 });
  }
});

Supabase Webhooks

Forward database webhook events (triggers, realtime errors) to Squasher:

Create a Database Webhook in the Supabase dashboard
Set the endpoint to: https://ingest.squasher.ai/v1/drain/supabase/YOUR_PROJECT_ID
Add the header: x-squasher-key: sq_pk_your_api_key

Database Logs via OTel Collector

For PostgreSQL query errors from your Supabase database, see the Docker integration guide to set up an OTel Collector that reads database logs.

Agent handoff

Set up Supabase telemetry for Squasher project <project_id>. Use direct HTTP for Edge Functions, a managed drain for webhook-style events, or an OTel Collector for database logs. Keep keys in Supabase secrets and verify with one function error or webhook event.
