We’re improving the Mappings feature in Advanced Settings to make it clearer how values are resolved and how to work with nested configuration data. It now includes a dedicated Template Substitution section and better examples for nested values.
Dynamic values can already be used in request headers and body, and now they also work in URLs and query strings.
With a single syntax, {{ var.NAME }}, you can apply dynamic values across the entire outbound request. This enables API versioning, multi-tenant routing, pagination, and more, all driven from your configuration without hardcoding.
