Catch Broken APIs & 500 Errors Before Your Customers Do

Catch Broken APIs and Webhooks Before Your Users Tweet About It

Your homepage might be loading fine, but what about your /api/v1/checkout, /api/auth/callback, or Stripe webhook receiver?

A subtle backend exception, bad database migration, or memory spike can return 500 Internal Server Error or hang indefinitely while your landing page looks completely healthy. If you only monitor domain roots, you miss the silent revenue-killing API bugs.

Pingzo gives backend developers, API providers, and SaaS founders continuous, multi-region API checks with instant mobile alerts.

1. Why Standard Website Pings Aren't Enough for APIs

• Payload & Status Code Masking: A broken endpoint might return HTTP 200 with an empty body or {"error": "Database connection pool exhausted"}. Pingzo asserts both HTTP status codes and JSON response body keys.
• Geographic Latency Blindspots: An API might respond in 45ms from your local region, but suffer 2.5-second timeouts for users in Europe or Asia. Pingzo verifies response latencies across North America, Europe, and Asia every 60 seconds.
• Authentication & Header Requirements: Protected microservices require custom Authorization: Bearer <token> or API key headers. Pingzo lets you configure custom HTTP headers, request bodies, and method verbs (GET, POST, PUT, DELETE).

2. Setting Up API Endpoint Checks in 60 Seconds

1. Add Your Target API URL: Enter your endpoint (e.g. https://api.yourdomain.com/v1/health or /v1/auth).
2. Configure Response Assertions:
   • Expected HTTP Status: 200 OK
   • Keyword Assertion: Confirm response contains "status":"healthy" or "success":true
   • Maximum Acceptable Latency: Trigger a warning if response exceeds 1000ms.
3. Choose Alert Destination: Receive instant failure alerts directly to WhatsApp, Telegram, Discord, Slack, or Email.

3. Top API Scenarios to Monitor

• Payment & Checkout Endpoints: Ensure payment gateway webhooks and cart tokenization APIs remain responsive 24/7.
• Authentication & OAuth Flows: Monitor Google/GitHub OAuth callback handlers and JWT token refresh services.
• Third-Party API Integrations: Verify upstream dependencies (OpenAI, Resend, Twilio, AWS S3) haven't introduced latency bottlenecks.
• Microservices & Webhooks: Catch inter-service communication timeouts before frontend users encounter failed requests.
