Network Conformance Checks

Network monitoring conformance checks extend your monitors to verify not just whether an API responds correctly, but whether the underlying network and certificate infrastructure meets your requirements — including DNS, TLS handshake, CDN routing, and cross-cloud performance.

TLS certificate expiry monitoring​

APIContext can alert you before your API's TLS certificate expires — giving you time to renew before users are affected.

Configure expiry alerts​

  1. Open a monitor and go to Network Conformance settings.
  2. Under TLS Certificate, enable expiry monitoring.
  3. Set alert thresholds:
ThresholdWhen to alert
30-day warningCertificate expires within 30 days
7-day warningCertificate expires within 7 days
1-day criticalCertificate expires within 24 hours

You can enable one or more thresholds. Each triggers an alert through your configured notification channels.

CDN allowlist verification​

If your API is served through a CDN, you can verify that requests are being routed through your expected CDN network and not bypassing it.

APIContext supports allowlist verification for ~24 CDN providers, including:

  • Akamai
  • Amazon CloudFront
  • Azure CDN
  • Cloudflare
  • Fastly
  • Google Cloud CDN
  • Imperva / Incapsula
  • Verizon / Edgecast
  • And more — see your project's conformance settings for the full list.

Configure a CDN allowlist check​

  1. In the monitor's Network Conformance settings, select CDN Allowlist.
  2. Choose the expected CDN provider(s).
  3. APIContext verifies that the X-Cache, X-CDN, or server header matches the expected CDN signature.

Geo-fencing and data sovereignty checks​

Data sovereignty requirements may require that API traffic stays within specific geographic boundaries. APIContext can verify that:

  • Requests are served from nodes in an approved region
  • Responses do not contain IP addresses or headers indicating routing through restricted jurisdictions

Configure geo-fencing​

  1. In Network Conformance, enable Geo-fencing.
  2. Select the approved regions (e.g., EU only, US only).
  3. APIContext runs monitors from nodes in the approved regions and fails if a response indicates routing outside them.
