Baserow ➔ Supabase Webhook Pipeline Specification Webhook Specification, Headers & Security

Technical Integration Summary

Developer documentation for integrating Baserow ➔ Supabase Webhook Pipeline Specification webhooks into backend applications. Secure your endpoint with HMAC signature checking and payload validation.

Supported Events: resource.created resource.updated resource.deleted event.triggered

Authentication & Request Headers

Security validation specs for Baserow ➔ Supabase Webhook Pipeline Specification endpoints:

X-Webhook-Signature-256: sha256=e39948eb5499ef4264f548a2502547ae

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_baserow-to-supabase.html_76367",
  "event": "resource.created",
  "created_at": 1789764045,
  "data": {
    "resource_id": "res_382",
    "status": "active"
  }
}

cURL Request Simulation

curl -X POST https://your-domain.com/webhook/baserow-to-supabase.html \
  -H "Content-Type: application/json" \
  -H "X-Webhook-Signature-256: sha256=e39948eb5499ef4264f548a2502547ae" \

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 Baserow ➔ 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

What is the response timeout for Baserow ➔ Supabase Webhook Pipeline Specification webhooks?

Your endpoint must return an HTTP 2xx response within 2000ms. Offload heavy processing (email, DB writes) to an asynchronous task queue.

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.

How to verify Baserow ➔ Supabase Webhook Pipeline Specification webhook authenticity?

Compute the HMAC SHA-256 hash on the raw request body using your shared secret and compare it against the incoming signature header using time-constant comparison.
