🗺️Integration flow overview

Welcome to the Oten IDP developer integration guide! This page provides a comprehensive overview of the entire integration process, giving you a roadmap before diving into the detailed implementation steps.

🎯 What you'll learn

This overview covers:

• Complete integration workflow from setup to production

• Step-by-step roadmap with clear milestones

• JAR (JWT-Secured Authorization Request) requirements - CRITICAL for Oten IDP

• Different client types and their specific implementation paths

• Security considerations and best practices

• Testing and deployment strategies

🚨 Before you start - JAR requirement

CRITICAL: Oten IDP requires JAR (JWT-secured authorization request) for ALL authorization requests.

Key Points:

• ❌ Traditional OAuth query parameters are REJECTED

• ✅ All OAuth parameters must be in a signed JWT

• Choose HS256 (client secret) or EdDSA (key pair)

Integration roadmap

Here's your complete journey from start to finish:

Simple integration workflow

Step-by-step guide navigation

Step	Page	Description	Time Estimate
Setup	Prerequisites	Environment setup, Oten registration	30 minutes
JAR	JAR requirement	CRITICAL: Understanding JAR requirements	15 minutes
Library	Choose OAuth library	Select JAR-compatible library	20 minutes
Config	Configure client	Set up OAuth client with JAR	30 minutes
Auth	Authorization flow	Implement JAR authorization	45 minutes
Callback	Handle callback	Process OAuth callback	30 minutes
Tokens	Token management	Secure token storage & refresh	45 minutes

Total estimated time: 3-4 hours for basic implementation

What type of app are you building?

Choose your path based on what you're building:

Web app with backend server

Examples: Traditional websites, admin panels, internal tools

What you have	What you need
Backend server (Node.js, Python, Go, etc.)	✅ Easiest path
Database for user sessions	✅ Store secrets securely
Server-side rendering	✅ Full control over auth

Go to: Server-side integration guide

Frontend-only app (SPA)

Examples: React app, Vue app, Angular app (no backend)

What you have	What you need
Frontend framework only	❌ More complex
No backend server	⚠️ Need backend service for JAR
Browser-based app	⚠️ Cannot store secrets safely

You Need: A small backend service to handle JAR creation Go to: SPA integration guide

Mobile app

Examples: iOS app, Android app, React Native

What you have	What you need
Mobile application	❌ Most complex
App store distribution	⚠️ Need backend service for JAR
Native or hybrid app	⚠️ Deep link handling required

You Need: Backend service + deep link setup Go to: Mobile integration guide

How to sign your requests (JAR)

Oten requires signed requests for security. Choose your signing method:

Method 1: Use client secret (easier)

For beginners and development

Pros	Cons	Best For
✅ Simple setup	❌ Less secure	Development
✅ No key management	❌ Shared secret	Internal apps
✅ Quick to implement		Getting started

How it works: Use your client secret (password) to sign requests

Method 2: Use key pairs (more secure)

For production and public apps

Pros	Cons	Best For
✅ Very secure	❌ More complex setup	Production
✅ No shared secrets	❌ Key management needed	Public apps
✅ Industry standard		High security

How it works: Generate a key pair, keep private key secret, register public key

🚀 Quick recommendations

👨‍💻 For beginners

Start with Go + Client secret method

Why Go?	Why Client secret?
✅ We provide ready-made library	✅ Simpler to implement
✅ Built-in JAR support	✅ No key management
✅ Complete examples	✅ Works for most cases
✅ 1-2 hours to implement	✅ Good for learning

🏭 For production apps

Use EdDSA for better security

Security level	Method	Best for
🟡 Good	HS256	Internal tools, development
🟢 Better	EdDSA	Production, public apps

💡 Simple decision tree

Question 1: Is this for production?

• No → Use Client Secret method

• Yes → Continue to Question 2

Question 2: Do you have a backend server?

• Yes → Use Key Pairs method

• No → You need to build a small backend service first

🎯 What happens when user logs in?

Simple 5-step process:

Step	What happens	Who does it
1️⃣	User clicks "Login"	User
2️⃣	App creates signed request (JAR)	Your app
3️⃣	User enters password at Oten	User
4️⃣	Oten sends back a code	Oten
5️⃣	App exchanges code for tokens	Your app

Result: User is logged in and can use your app!

🛠️ What you need to build

For Client secret method (easier)

1. Sign requests with your client secret

2. Handle the callback when user returns

3. Store tokens safely

4. Use tokens for API calls

For Key pairs method (more secure)

1. Generate key pair (one time setup)

2. Register public key with Oten

3. Sign requests with private key

4. Handle the callback when user returns

5. Store tokens safely

6. Use tokens for API calls

Ready to start?

Choose your path:

Recommended for beginners

Go with Client secret - Easiest path, 1-2 hours

For Other languages

Choose your library - More setup needed, 2-4 hours

For production apps

Key pairs setup - Most secure, requires key management
