Argo Events Webhook Quick Fix - Webhook Event Source

Argo Events Webhook event source receives HTTP Webhook requests from external systems. Misconfigured Webhooks cause connection failures or unprocessed events. This guide covers the fix.

Quick Fix

Wrong

webhook:
  example:
    port: "12000"
    endpoint: /webhook
    method: POST

The issue: no maxPayloadSize limit, no readTimeout, and no writeTimeout. Large payloads can crash the event source, and slow clients can exhaust connections.

Right

webhook:
  example:
    port: "12000"
    endpoint: /webhook
    method: POST
    maxPayloadSize: "10mb"
    readTimeout: "30s"
    writeTimeout: "30s"
    service:
      ports:
      - port: 12000
        targetPort: 12000

# Expected output after applying the fix
# Webhook endpoint: POST /webhook on port 12000
# Max payload: 10MB, Timeout: 30s
# Service created for external access
# Test: curl -X POST http://host:12000/webhook -d '{"test":true}'

Prevention

• Set maxPayloadSize to prevent resource exhaustion
• Configure readTimeout and writeTimeout for connection management
• Create a service to expose the Webhook endpoint
• Use HTTPS with ingress controller for production Webhooks
• Validate Webhook signature in event source configuration
