Getting started

Requirements

This library follows the same support policy as Go. The last two major Go releases are actively supported and compatibility issues will be fixed. While you may find that older versions of Go may work, we will not actively test and fix compatibility issues with these versions.

Go 1.20+

Installation

go get github.com/auth0/go-auth0

Usage

Authentication API Client

The Authentication API client is based on the Authentication API docs.

Create an Authentication API client by providing the details of your Auth0 Application.

import (
	github.com/auth0/go-auth0
	github.com/auth0/go-auth0/authentication
	github.com/auth0/go-auth0/authentication/database
	github.com/auth0/go-auth0/authentication/oauth
)

func main () {
	// Get these from your Auth0 Application Dashboard.
	domain := "example.us.auth0.com"
	clientID := "EXAMPLE_16L9d34h0qe4NVE6SaHxZEid"
	clientSecret := "EXAMPLE_XSQGmnt8JdXs23407hrK6XXXXXXX"

	// Initialize a new client using a domain, client ID and client secret.
	authAPI, err := authentication.New(
		context.Background(),
		domain,
		authentication.WithClientID(clientID)
		authentication.WithClientSecret(clientSecret) // Optional depending on the grants used
	)
	if err != nil {
		log.Fatalf("failed to initialize the auth0 authentication API client: %+v", err)
	}

	// Now we can interact with the Auth0 Authentication API.
	// Sign up a user
	userData := database.SignupRequest{
		Connection: "Username-Password-Authentication",
		Username:   "mytestaccount",
		Password:   "mypassword",
		Email:      "mytestaccount@example.com",
	}

	createdUser, err := authAPI.Database.Signup(context.Background(), userData)
	if err != nil {
		log.Fatalf("failed to sign user up: %+v", err)
	}

	// Login using OAuth grants
	tokenSet, err := authAPI.OAuth.LoginWithAuthCodeWithPKCE(context.Background(), oauth.LoginWithAuthCodeWithPKCERequest{
		Code:         "test-code",
		CodeVerifier: "test-code-verifier",
	}, oauth.IDTokenValidationOptionalVerification{})
	if err != nil {
		log.Fatalf("failed to retrieve tokens: %+v", err)
	}
}

Note The context package can be used to pass cancellation signals and deadlines to the Client for handling a request. If there is no context available then context.Background() can be used.

Management API Client

The Management API client is based on the Management API docs.

package main

import (
	"context"
	"log"

	"github.com/auth0/go-auth0"
	"github.com/auth0/go-auth0/management"
)

func main() {
	// Get these from your Auth0 Application Dashboard.
	// The application needs to be a Machine To Machine authorized
	// to request access tokens for the Auth0 Management API,
	// with the desired permissions (scopes).
	domain := "example.auth0.com"
	clientID := "EXAMPLE_16L9d34h0qe4NVE6SaHxZEid"
	clientSecret := "EXAMPLE_XSQGmnt8JdXs23407hrK6XXXXXXX"

	// Initialize a new client using a domain, client ID and client secret.
	// Alternatively you can specify an access token:
	// `management.WithStaticToken("token")`
	auth0API, err := management.New(
		domain,
		management.WithClientCredentials(context.Background(), clientID, clientSecret),
	)
	if err != nil {
		log.Fatalf("failed to initialize the auth0 management API client: %+v", err)
	}

	// Now we can interact with the Auth0 Management API.
	// Example: Creating a new client.
	client := &management.Client{
		Name:        auth0.String("My Client"),
		Description: auth0.String("Client created through the Go SDK"),
	}

	// The passed in client will get hydrated with the response.
	// This means that after this request, we will have access
	// to the client ID on the same client object.
	err = auth0API.Client.Create(context.Background(), client)
	if err != nil {
		log.Fatalf("failed to create a new client: %+v", err)
	}

	// Make use of the getter functions to safely access
	// fields without causing a panic due nil pointers.
	log.Printf(
		"Created an auth0 client successfully. The ID is: %q",
		client.GetClientID(),
	)
}

Note The context package can be used to pass cancellation signals and deadlines to the Client for handling a request. If there is no context available then context.Background() can be used.

Rate Limiting

The Auth0 Management API imposes a rate limit on all API clients. When the limit is reached, the SDK will handle it in the background by retrying the API request when the limit is lifted.

Note The SDK does not prevent http.StatusTooManyRequests errors, instead it waits for the rate limit to be reset based on the value of the X-Rate-Limit-Reset header as the amount of seconds to wait.
