Before you begin

This guide shows you how to add Okta authentication to your API endpoints. When you've finished following the steps, clients will need a token generated by Okta to call your protected endpoints.

These steps apply to back-end APIs that are serving single-page apps or mobile apps that use Okta to sign users in. If you are building a web app that is served by a server framework, see Sign users in to your web app.

This guide assumes that you:

• Have an Okta Developer Edition organization. Don't have one? Create one for free.
• Have a project or application that you want to add authentication to.

If you don't have an existing app, or are new to building apps, start with this documentation:

• ASP.NET
• ASP.NET Core 2.x
• ASP.NET Core 3.x
• Go
• Node Express
• PHP
• Spring Boot

The ASP.NET Web API quickstart teaches you the basics of building a Web API project.

Or, if you want to skip this guide and just download a working sample app, download our ASP.NET Web API example.
