Which language is primarily used for writing Synthetic monitoring API scripts in Instana?

Instana’s Synthetic Monitoring module allows administrators to script user journeys and API checks to validate service performance and uptime. According to official IBM documentation, "Synthetic monitoring API scripts use JavaScript as the scripting language for configuring user flows and custom API tests." Instana has designed its synthetic user interface to interpret JavaScript natively which provides powerful, flexible constructs for simulating user interactions, custom API payloads, test logic, and error handling. This ensures broad compatibility with real browser environments and highly customizable synthetic scenarios. Java, Python, and Go are not supported for browser-based or synthetic API scripting in Instana’s synthetic monitors. JavaScript is chosen for its ubiquity and ease of integration with DOM-like and API interaction patterns, supporting the most common web-based automation needs as described in the documentation.
