A high-performance tool for swift app development is here! Introducing the ultimate webhook testing suite, designed to help developers test and inspect incoming webhooks in real-time. This powerful Actor is optimized for Apify Standby Mode, providing sub-10ms logic execution and zero cold-start latency.

Interactive Demos

Run the following command while the Actor is active to see real-time streaming:

  • Make sure the Actor is running locally on port 8080
  • Run npm start or use the npx webhook-debugger-logger option for a zero-install experience
  • Want to test the Docker image locally? Check out our Local Docker Testing Guide

Test and Inspect Webhooks Instantly

No more complex tunneling tools or localhost setup required. With this Actor, you can instantly test and inspect webhooks without running a local environment.

Custom Deployments

Configure the Actor via environment variables or JSON input for custom deployments:

  • Example: 5 URLs, 72h retention, 100MB payload limit

INPUT='{"urlCount": 5, "retentionHours": 72, "maxPayloadSize": 104857600}' npm start

Features

This Actor offers a range of features to help you debug and test webhooks:

  • API mocking with custom status/latency
  • Secure forwarding for Shopify and other services
  • JSON Schema validation for data integrity
  • Live SSE streaming for real-time updates

Benefits

By using this Actor, you can:

  • Debug Stripe, GitHub, Shopify, and Zapier workflows instantly
  • Test complex payloads from CI/CD triggers without waiting for real builds
  • Securely forward Shopify hooks to your local development environment
  • Act as a high-performance validator for your automation workflows

Configurations

This Actor supports various configurations to suit your needs:

  • URL Count: Create 100+ webhooks (vs Platform UI limits) if your self-hosted instance has enough resources.
  • Retention: Keep data for 365 days. Fully configurable.
  • Payloads: Parse up to 100MB payloads by setting maxPayloadSize.
  • Rate Limit: Fully configurable for management endpoints (/logs, /info, /replay). Applied per client IP.

Hot-Reload

To change settings while running (e.g., enable debug logging), simply edit the configuration file and the Actor will apply changes automatically.

Enterprise Update

The Enterprise Update transforms this Actor into a professional API mocking and workflow tool:

  • API Key Auth: Require a secret token for every incoming webhook.
  • IP Whitelisting: Lock down your endpoints to specific IPs or CIDR ranges.
  • Rate Limiting: Protect management endpoints with configurable per-IP rate limits.
  • Sensitive Data Masking: Automatically redact known sensitive headers from logs.
  • SSRF Protection: Enterprise-grade Server-Side Request Forgery protection prevents scanning internal networks.
