Quick start guide

From zero to first webhook in 4 steps

Copy, paste, done. No SDK needed. Works with any HTTP client — or any agent framework.

Get your API key

Sign up for a free account (no credit card). Your API key is available immediately in the dashboard under Settings → API Keys. Export it as an env variable - never hardcode it.

Agents: POST to /v1/auth/signup with email + password to create an account programmatically. Your API key is returned in the response. No email verification required to start.

bash 
# Export your API key as an environment variable
export HOOKWING_API_KEY="hwk_live_YOUR_KEY_HERE"

# Verify it's set
echo "Key loaded: ${HOOKWING_API_KEY:0:12}..."

Create a webhook endpoint

One POST request creates a persistent endpoint. The response includes your unique webhook URL - share it with any service that can send HTTP POST requests.

bash 
curl -X POST https://api.hookwing.com/v1/endpoints \
  -H "Authorization: Bearer $HOOKWING_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "my-first-endpoint", "description": "Testing Hookwing"}'
json 
{
  "id":          "ep_01HX9Z3KQMR8TVYF2N",
  "name":        "my-first-endpoint",
  "url":         "https://api.hookwing.com/v1/ingest/ep_01HX9Z3K",
  "status":      "active",
  "created_at":  "2026-03-03T17:00:00Z"
}

Send a test event

POST any JSON payload to your webhook URL. Hookwing accepts any valid JSON body - no schema required. Headers, method, and timing are all recorded.

bash 
# Send a test event to your webhook URL
curl -X POST https://api.hookwing.com/v1/ingest/ep_01HX9Z3K \
  -H "Content-Type: application/json" \
  -H "X-Event-Type: order.created" \
  -d '{
    "event": "order.created",
    "order_id": "ord_9876",
    "customer": "[email protected]",
    "amount": 49.99,
    "currency": "USD"
  }'

Check delivery

Retrieve delivered events via API or the dashboard inspector. Each event includes the full payload, headers, delivery status, and timestamp. Replay any event with a single call.

bash 
# List events received by your endpoint
curl https://api.hookwing.com/v1/events?endpointId=ep_01HX9Z3K \
  -H "Authorization: Bearer $HOOKWING_API_KEY"
json 
{
  "events": [
    {
      "id":           "evt_01HX9Z7ABCDEF",
      "endpoint_id":  "ep_01HX9Z3K",
      "status":       "delivered",
      "method":       "POST",
      "latency_ms":   142,
      "received_at":  "2026-03-03T17:01:32Z",
      "body": {
        "event":     "order.created",
        "order_id": "ord_9876",
        "amount":   49.99
      }
    }
  ],
  "total": 1
}
SDKs & clients

Choose your language

No SDK required - but we've got you covered if you prefer one.

Node.js 
// npm install hookwing
import { Hookwing } from 'hookwing'
const hw = new Hookwing(process.env.HW_KEY)
await hw.endpoints.create('my-ep')
Python 
# pip install hookwing
from hookwing import Webhook
wh = Webhook("whsec_...")
event = wh.verify(payload, headers)
Go 
// go get github.com/gethookwing/hookwing-go
wh := hookwing.NewWebhook("whsec_...")
event, err := wh.Verify(payload, headers)
Ruby 
# gem install hookwing
wh = Hookwing::Webhook.new("whsec_...")
event = wh.verify(payload, headers)
REST / curl 
# No install needed
curl -X POST \
  https://api.hookwing.com/v1/endpoints \
  -H "Authorization: Bearer $HW_KEY"
