Webhook Testing

Create instant webhook endpoints to capture, inspect, and debug HTTP requests.

Why Use Webhook Testing?​

  • No deployment needed - Test webhooks during local development
  • Real-time inspection - See requests as they arrive
  • Request replay - Replay requests for debugging
  • Signature validation - Verify webhook signatures

Quick Start​

# Create a webhook endpoint
arm webhook create

# Output:
# ✓ Webhook created!
#   Endpoint: https://tunnelapi.in/webhook/abc123

Use this URL in your webhook provider (Stripe, GitHub, etc.)
