Authentication & Request Headers

Security validation specs for Stripe ➔ Vectorizer.AI Webhook Pipeline Specification endpoints:

X-Stripe➔Vectorizer.AIWebhookPipelineSpecification-Signature: t=1789764056,v1=fbd2ca8ca743870a73567cf3

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 (charge.succeeded)

{
  "id": "evt_stripe-to-vectorizer.html_74206",
  "event": "charge.succeeded",
  "created_at": 1789764056,
  "data": {
    "resource_id": "res_383",
    "status": "active"
  }
}

cURL Request Simulation

curl -X POST https://your-domain.com/webhook/stripe-to-vectorizer.html \
  -H "Content-Type: application/json" \
  -H "X-Stripe➔Vectorizer.AIWebhookPipelineSpecification-Signature: t=1789764056,v1=fbd2ca8ca743870a73567cf3" \
  -d '{"id": "evt_stripe-to-vectorizer.html_74206", "event": "charge.succeeded", "created_at": 1789764056, "data": {"resource_id": "res_383", "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 Stripe ➔ Vectorizer.AI 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

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.

What is the response timeout for Stripe ➔ Vectorizer.AI 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.

What to do when receiving HTTP 429 status from Stripe ➔ Vectorizer.AI Webhook Pipeline Specification?

A 429 status indicates your endpoint is being rate limited. Implement dynamic throttling or increase consumer worker threads in your queue worker.
