Signature Verification Implementations

Node.js (Express)

const crypto = require('crypto');
const expected = crypto.createHmac('sha256', secret).update(rawBody).digest('hex');
const isValid = crypto.timingSafeEqual(Buffer.from(expected), Buffer.from(signature));

Python (Flask / FastAPI)

import hmac, hashlib
expected = hmac.new(secret.encode(), raw_body, hashlib.sha256).hexdigest()
is_valid = hmac.compare_digest(expected, incoming_sig)

Sample Event Payload (resource.created)

{
  "id": "evt_make-to-supabase.html_96028",
  "event": "resource.created",
  "created_at": 1789764052,
  "data": {
    "resource_id": "res_294",
    "status": "active"
  }
}

cURL Request Simulation

curl -X POST https://your-domain.com/webhook/make-to-supabase.html \
  -H "Content-Type: application/json" \
  -H "X-Make.com➔SupabaseWebhookPipelineSpecification-Signature: t=1789764052,v1=cff5180c6bd308c4869fb1bb" \
  -d '{"id": "evt_make-to-supabase.html_96028", "event": "resource.created", "created_at": 1789764052, "data": {"resource_id": "res_294", "status": "active"}}'

HTTP Response Rules

Status Code	Status Meaning	Integration Action
`200 OK`	Success	Event payload validated and queued.
`400 Bad Request`	Malformed Payload	Check payload structure and JSON formatting.
`401 Unauthorized`	Signature Mismatch	Verify secret key and digest computation.
`500 Error`	Server Error	Triggers provider automated retry backoff.

Security Best Practices for Make.com ➔ Supabase Webhook Pipeline Specification

Always process incoming events asynchronously using a message queue. Never perform long-running DB queries or external API calls synchronously within the HTTP response handler.

Frequently Asked Questions

Should I restrict incoming IP addresses for Make.com ➔ Supabase Webhook Pipeline Specification?

While signature verification is primary, restricting traffic to published origin IP ranges adds a robust layer of perimeter security.

How to handle duplicate Make.com ➔ Supabase Webhook Pipeline Specification webhooks?

Store processed event IDs in an atomic storage like Redis with a set expiration. If an incoming ID exists, acknowledge with 200 OK immediately without re-triggering logic.

Why does signature validation fail on Express/Flask?

Your framework might be auto-parsing JSON. HMAC generation requires the exact raw byte buffer of the request body before JSON middleware alters keys or spacing.
