API Health Check

A practical example

Example: your CRM connector's credentials expire silently after a vendor-side change. A health check running every five minutes starts receiving 401 responses and alerts the ops channel within one cycle.

Without it, the dead connection could drop campaign data for days before anyone notices missing leads.

What to evaluate before investing

• Ask what the probe actually calls: a dedicated status endpoint or a representative real request.
• Verify alert routing and whether a failing check escalates if unacknowledged.
• Confirm the check frequency and whether it consumes your request quota meaningfully.

Limitations and tradeoffs

A passing health check proves liveness only; an API can respond to a minimal probe while real sync requests still fail due to payload or permission issues.
