Fireflies.ai ➔ Notion API Webhook Pipeline Specification Webhook Specification, Headers & Security

Technical Integration Summary

Developer documentation for integrating Fireflies.ai ➔ Notion API Webhook Pipeline Specification webhooks into backend applications. Secure your endpoint with HMAC signature checking and payload validation.

Supported Events: contact.creation deal.stage_change company.updated ticket.created

Authentication & Request Headers

Security validation specs for Fireflies.ai ➔ Notion API Webhook Pipeline Specification endpoints:

Authorization: Bearer sec_live_9784a80ba138ef02

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 (contact.creation)

{
  "id": "evt_fireflies-to-notion.html_45396",
  "event": "contact.creation",
  "created_at": 1789764048,
  "data": {
    "resource_id": "res_251",
    "status": "active"
  }
}

cURL Request Simulation

curl -X POST https://your-domain.com/webhook/fireflies-to-notion.html \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sec_live_9784a80ba138ef02" \
  -d '{"id": "evt_fireflies-to-notion.html_45396", "event": "contact.creation", "created_at": 1789764048, "data": {"resource_id": "res_251", "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 Fireflies.ai ➔ Notion API 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 to do when receiving HTTP 429 status from Fireflies.ai ➔ Notion API 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.

How to handle duplicate Fireflies.ai ➔ Notion API 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.
