Advanced HTTP/HTTPS Endpoint Monitoring

Full control over every HTTP check. Custom methods, headers, request bodies, basic authentication, regex validation, and expected status codes. Monitor APIs and websites with precision.

🔧

Custom HTTP Methods

Choose GET, HEAD, POST, PUT, or DELETE for each monitor. Test your API endpoints exactly as your application calls them, not just with simple GETs.

🔒

Basic Authentication

Monitor password-protected endpoints with built-in basic auth support. Credentials are encrypted at rest and never exposed in logs or alerts.

📝

Regex Body Validation

Define a regular expression pattern that the response body must match. Catch API errors, content changes, or missing data that a simple status code check would miss.

🎯

Expected Status Codes

Define which HTTP status codes mean "up" for each monitor. A 301 redirect might be correct for one URL but an error for another. You decide.

📦

Request Body Support

Send custom JSON or form data with POST/PUT requests. Monitor webhook endpoints, form submissions, and API mutations with realistic payloads.

Response Time Tracking

Every check records the full response time. Track performance trends, identify slow endpoints, and set thresholds that trigger alerts when response times spike.

HTTP Monitor Configuration:
────────────────────────
URL: https://api.example.com/health
Method: POST
Auth: Basic (api_user:***)
Body: {"check":"deep"}
Expected: 200, 201
Regex: "status":\s*"healthy"
Interval: 30 seconds
Timeout: 30s
✓ Monitor active — next check in 12s

Monitor APIs Like a Developer

GoScreenAPI's HTTP monitoring goes far beyond simple "is it up?" checks. Configure each monitor to replicate real API calls with the exact method, headers, authentication, and payload your application uses.

The regex validation engine lets you verify response content, not just status codes. Catch scenarios where your API returns 200 but with an error message in the body, or when a CDN serves stale content instead of your actual page.

GET / HEAD / POST PUT / DELETE Basic Auth Regex Match Custom Body

Common HTTP Monitoring Use Cases

REST API health endpoints with POST body
Admin panels behind basic authentication
E-commerce checkout flow validation
CDN content verification with regex
Webhook receiver endpoint testing
GraphQL endpoint monitoring with POST
Microservice inter-dependency checks
SSL certificate and HTTPS redirect validation

Beyond Simple Ping: True HTTP Intelligence

Traditional uptime monitors send a GET request and check for a 200 response. That works for simple websites, but modern applications need more. Your API might return 200 with an error payload. Your CDN might serve a cached error page with a 200 status. Your authentication endpoint might accept any request but return invalid tokens.

GoScreenAPI's HTTP monitoring solves these problems with deep response inspection. The regex validation engine parses the response body and verifies that the content matches your expectations. Combined with custom HTTP methods and request bodies, you can monitor complex API workflows that other tools simply cannot handle.

For teams managing microservice architectures, HTTP monitoring with custom methods is essential. Monitor your internal service mesh with POST-based health checks, verify that authentication services issue valid tokens, and ensure that your data pipeline endpoints accept and process payloads correctly — all from a single dashboard.
