Kong Gateway replace response status code

I have seen both the Response Transformer Plugin and the Advanced Response Transformer Plugin that will allow you to change, for example, the body of a particular response, for example by setting the declarative way:

config.replace.body='{\"error\": \"internal server error\"}'"

How could I change the status code of a response, for example if I wanted to always return 200 even when other plugins such as the rate limiter one intercept the request?

Is there another plugin that may support this functionality? Or should I write a custom plugin?


  • A possible way is to use the serverless-function plugin: https://docs.konghq.com/hub/kong-inc/serverless-functions/ in particular the post-function plugin.

    This plugin allows you to apply a custom lua function, runned after the other plugins, e.g. to the kong response. To change the status code you could use something like:

            return function()

    and apply this snippet of code to the header_filter phase (a parameter of the plugin conf.).

    Another possibility is to use the exit-plugin https://docs.konghq.com/hub/kong-inc/exit-transformer/ to change the Kong's response.
