- To apply a custom plugin to an API you must modify the API definition and add the plugin information to one of the areas of the API Request Lifecycle mentioned above.

Tyk recommends using Go plugins for performance, flexibility, and nativity reasons (All Tyk components are written in Go).
The following languages are supported for custom plugins:
- Golang native plugins - fast, native performance
- Python, Lua, gRPC (Rich Plugins) - ultimate flexibility in the language of implementation, however, there are some performance and management overheads when compared to native GoLang plugins
