Go Reference Test Go Report Card

Note: This library is under active development as we expand it to cover our (expanding!) API. Consider the public API of this package a little unstable as we work towards a v1.0.

A Go library for interacting with Cloudflare's API v4. This library allows you to:

  • Manage and automate changes to your DNS records within Cloudflare
  • Manage and automate changes to your zones (domains) on Cloudflare, including adding new zones to your account
  • List and modify the status of WAF (Web Application Firewall) rules for your zones
  • Fetch Cloudflare's IP ranges for automating your firewall whitelisting

A command-line client, flarectl, is also available as part of this project.


You need a working Go environment. We officially support only currently supported Go versions according to Go project's release policy.

go get

Getting Started

package main

import (


func main() {
	// Construct a new API object using a global API key
	api, err := cloudflare.New(os.Getenv("CLOUDFLARE_API_KEY"), os.Getenv("CLOUDFLARE_API_EMAIL"))
	// alternatively, you can use a scoped API token
	// api, err := cloudflare.NewWithAPIToken(os.Getenv("CLOUDFLARE_API_TOKEN"))
	if err != nil {

	// Most API calls require a Context
	ctx := context.Background()

	// Fetch user details on the account
	u, err := api.UserDetails(ctx)
	if err != nil {
	// Print user details

Also refer to the API documentation for how to use this package in-depth.

Experimental improvements

This library is starting to ship with experimental improvements that are not yet ready for production but will be introduced before the next major version. See experimental README for full details.
