API Docs

Overview

The Pabbly Hook API lets you programmatically manage webhook connections, transformations, events, and folders. Build, modify, and route incoming webhook payloads to downstream services through code, and automate the connections you would otherwise wire up in the Pabbly Hook dashboard.

Example request

curl https://hook.pabbly.com/api/v1/folders \
  -u {{YOUR_API_KEY}}:{{YOUR_SECRET_KEY}}

Base URL

All endpoints are relative to the base URL below. Combine the base URL with the path on each endpoint to get the full request URL.

Base URL

https://hook.pabbly.com/api/v1

Requests and responses

The API accepts JSON request bodies and returns JSON responses. Send Content-Type: application/json on every request that has a body. Path parameters are interpolated into the URL; query parameters and body fields are documented per endpoint.

Success response

{
  "success": true,
  "data": { /* … */ }
}

Errors

When a request fails, the response status code reflects the error category and the body carries a human-readable message. Treat any non-2xx status as a failure.

Status	Meaning
200, 201	Success
400	Bad request — missing or malformed parameters
401	Unauthorized — missing or invalid API credentials
404	Not found — the resource does not exist
429	Too many requests
5xx	Server error — retry with backoff

Error response

{
  "success": false,
  "error": "A human-readable explanation"
}

Authentication

The Pabbly Hook API uses HTTP Basic Auth. Every request must include your API Key and Secret Key as the username and password.

Auth header

Authorization: Basic <base64({{YOUR_API_KEY}}:{{YOUR_SECRET_KEY}})>

Getting your credentials

Sign in to your Pabbly account and navigate to Settings → API Settings → Generate the Keys. You will see (or be able to generate) an API Key and a matching Secret Key. Treat the Secret Key like a password.

Making authenticated requests

Send your API Key as the HTTP Basic username and your Secret Key as the password on every request. The examples on the right show how to call /folders with proper authentication.

cURL

curl https://hook.pabbly.com/api/v1/folders \
  -u {{YOUR_API_KEY}}:{{YOUR_SECRET_KEY}}

Node.js

const credentials = Buffer
  .from('{{YOUR_API_KEY}}:{{YOUR_SECRET_KEY}}')
  .toString('base64');

const response = await fetch(
  'https://hook.pabbly.com/api/v1/folders',
  { headers: { Authorization: `Basic ${credentials}` } }
);
const data = await response.json();

Python

import requests
from requests.auth import HTTPBasicAuth

response = requests.get(
    'https://hook.pabbly.com/api/v1/folders',
    auth=HTTPBasicAuth('{{YOUR_API_KEY}}', '{{YOUR_SECRET_KEY}}'),
)
data = response.json()

Keep your credentials secret

Your credentials grant full access to your account. Never embed them in browser-side code, commit them to version control, or share them in support tickets. If you suspect a credential has been exposed, rotate it from the dashboard (Settings → API Settings → Generate the Keys) and update any servers that use it.
