Amberflo.io API Metering

This plugin allows you to understand customer API usage and implement usage-based price & billing by metering the requests with Amberflo.io.

It supports high-volume HTTP(S) usage without adding latency.

Amberflo is the simplest way to integrate metering into your application. Sign up for free to get started.

How it works

This plugin intercepts the requests, detects which customer is making it, generates a meter event and sends it to Amberflo.

Customer detection occurs via inspection of the request headers. You can configure Kong Gateway to inject the customerId as a header before this plugin runs. For example, if you use the Key Authentication plugin, this occurs automatically.

To avoid impacting the performance of your gateway, the plugin batches the meter records and sends them asynchronously to Amberflo.

Installation

This is a server plugin implemented in Go. You only need to make the binary available to Kong Gateway:

GOBIN=/tmp go install github.com/amberflo/kong-plugin-amberflo@latest
mv /tmp/kong-plugin-amberflo /usr/local/bin/amberflo

Then, register the plugin in your kong.conf file:

plugins = bundled,amberflo

pluginserver_names = amberflo

pluginserver_amberflo_start_cmd = /usr/local/bin/amberflo
pluginserver_amberflo_query_cmd = /usr/local/bin/amberflo -dump

Finally, restart Kong Gateway:

kong restart
