Synthetic API Monitoring: How to Test Complex User Flows and Ensure Reliability

Modern applications often rely on multiple API calls to complete a single user action. Downtime or slow responses in any step can break the flow and frustrate users. Synthetic API monitoring allows you to simulate these workflows proactively.

1. What is Synthetic API Monitoring?

Unlike basic uptime checks, synthetic monitoring runs pre-defined sequences of API requests to test how your service behaves under real-world scenarios. It ensures that each step in a multi-step workflow works as expected.

2. Benefits of Synthetic Monitoring

Catch errors before users do: Detect failures or slow responses in complex flows.
Measure performance: Track response times for each step of your APIs.
Ensure reliability: Validate that your services behave correctly even under heavy usage.

3. Set Up Synthetic Checks with UptyBots

UptyBots lets you configure multi-step API tests easily. Define endpoints, expected responses, and request sequences, and receive alerts if anything goes wrong.

4. Use Cases

eCommerce checkout workflows
Login and authentication flows
Data synchronization between services
Multi-step form submissions

5. Monitor Continuously

Synthetic monitoring runs at regular intervals from multiple locations worldwide. You’ll know immediately if an API step fails, enabling you to fix issues before they affect customers.
