Step by Step Guide to Building a OneLogin API Integration in Go

Introduction

Hey there, fellow Go enthusiast! Ready to dive into the world of OneLogin API integration? You're in for a treat. We'll be using the onelogin-go-sdk package to make our lives easier. Let's get cracking!

Prerequisites

Before we jump in, make sure you've got:

• Go installed (I know, obvious, right?)
• A OneLogin account with API credentials (if you don't have this, go grab it now – I'll wait)

Setting up the project

First things first, let's set up our project:

mkdir onelogin-integration
cd onelogin-integration
go mod init onelogin-integration
go get github.com/onelogin/onelogin-go-sdk

Easy peasy, right? Now we're ready to rock and roll.

Initializing the OneLogin client

Let's get that client up and running:

package main

import (
    "github.com/onelogin/onelogin-go-sdk/pkg/client"
)

func main() {
    c, err := client.NewClient(&client.APIClientConfig{
        ClientID:     "your_client_id",
        ClientSecret: "your_client_secret",
        Region:       "us",
    })
    if err != nil {
        panic(err)
    }
    // We're in business!
}

Authentication

Authentication is handled automatically by the SDK. It'll generate and refresh tokens as needed. Neat, huh?

Basic API operations

Let's dive into some basic operations. We'll cover retrieving, creating, updating, and deleting users.

Retrieving user information

users, err := c.Services.UsersV2.Query(&users.UserQuery{})
if err != nil {
    // Handle error
}
for _, user := range users {
    fmt.Printf("User: %s\n", user.Email)
}

Creating a new user

newUser := users.User{
    Email:     "[email protected]",
    FirstName: "New",
    LastName:  "User",
}
createdUser, err := c.Services.UsersV2.Create(&newUser)
if err != nil {
    // Handle error
}
fmt.Printf("Created user with ID: %d\n", createdUser.ID)

Updating user attributes

updatedUser := users.User{
    ID:        123, // The user's ID
    FirstName: "Updated",
}
_, err := c.Services.UsersV2.Update(&updatedUser)
if err != nil {
    // Handle error
}

Deleting a user

err := c.Services.UsersV2.Destroy(123) // User ID
if err != nil {
    // Handle error
}

Advanced operations

Now that you've got the basics down, let's tackle some more advanced stuff.

Managing roles and permissions

roles, err := c.Services.RolesV2.Query(&roles.RoleQuery{})
if err != nil {
    // Handle error
}
for _, role := range roles {
    fmt.Printf("Role: %s\n", role.Name)
}

Handling multi-factor authentication

factors, err := c.Services.MFAv2.ListFactors(123) // User ID
if err != nil {
    // Handle error
}
for _, factor := range factors {
    fmt.Printf("MFA Factor: %s\n", factor.Type)
}

Working with apps and SSO

apps, err := c.Services.AppsV2.Query(&apps.AppQuery{})
if err != nil {
    // Handle error
}
for _, app := range apps {
    fmt.Printf("App: %s\n", app.Name)
}

Error handling and best practices

Always check for errors and handle them gracefully. The SDK includes rate limiting, but it's good practice to implement your own backoff strategy for heavy usage.

if err != nil {
    log.Printf("Error occurred: %v", err)
    // Implement retry logic or graceful degradation
}

Testing the integration

Don't forget to write tests! Here's a quick example:

func TestUserCreation(t *testing.T) {
    // Set up test client
    c, _ := client.NewClient(&client.APIClientConfig{
        ClientID:     "test_client_id",
        ClientSecret: "test_client_secret",
        Region:       "us",
    })

    newUser := users.User{
        Email:     "[email protected]",
        FirstName: "Test",
        LastName:  "User",
    }
    createdUser, err := c.Services.UsersV2.Create(&newUser)
    
    assert.NoError(t, err)
    assert.NotNil(t, createdUser)
    assert.Equal(t, newUser.Email, createdUser.Email)
}

Conclusion

And there you have it! You've just built a solid OneLogin API integration in Go. Pretty cool, right? Remember, this is just scratching the surface. The onelogin-go-sdk has a ton more features to explore.

Keep coding, keep learning, and most importantly, have fun with it! If you need more info, check out the OneLogin API docs and the onelogin-go-sdk GitHub repo.

Now go forth and integrate with confidence! 🚀
