Heartbeat vs Synthetic Monitoring: Architectural Comparison

Use synthetic monitoring for multi-step customer-facing API flows (e.g. user authentication, token exchange, search queries, checkout pipelines) where you need to continuously verify latency and data correctness from outside your infrastructure.

Yes. In modern microservice architectures, an API request tested via synthetic monitoring often queues an asynchronous task processed by a background worker. Combining synthetic monitoring (for the intake API) with heartbeat monitoring (for the queue worker) ensures that both synchronous ingestion and asynchronous execution are fully covered without blind spots.
