In Kong, plugins can be thought of as policy enforcers. In the case of rate limiting, Kong offers two plugins: An open source one and Enterprise. Both plugins can limit requests per consumer, route, service or globally. Configuring the same plugin is also possible on a more than level. When this occurs, an order of precedence is used to determine which configuration to run. With this capability, it is possible to apply fine-grained policy control. In this article, we cover an advanced use case.

When testing APIs, software engineers often repeat identical values across multiple requests, but who wants to waste time typing the same values every time? Insomnia’s environment variables solve this problem by allowing you to define a value once as an environment variable and reference that value wherever it’s needed. Insomnia also enables you to override certain variables using sub-environments or folder environments.
