To introduce authentication using Ory Network in your React and Go applications, you can follow these steps: 1. Create a Go application and secure it with Ory: - First, create a Go app by running the following commands:

mkdir your-project        cd your-project        touch main.go handler.go middleware.go index.html        go mod init <http://github.com/<your-name>/your-project|github.com/<your-name>/your-project>

- Install the Ory SDK which allows you to interact with Ory APIs:

go get -u <http://github.com/ory/client-go|github.com/ory/client-go>

- You can find more details [here](https://www.ory.sh/docs/getting-started/integrate-auth/go). 2. Integrate authentication into your React application: - Create a new React project:

npx create-react-app my_project --template typescript        cd my_project

- Install the Ory SDK:

npm i --save @ory/client

- You can find more details [here](https://www.ory.sh/docs/getting-started/integrate-auth/react). 3. Set up Ory Network: - Set up the Ory SDK URL which you can find in the [Ory Console](https://console.ory.sh/projects/current/developers/guides)

export ORY_SDK_URL=https://{project.slug}.<http://projects.oryapis.com|projects.oryapis.com>

- Start the Ory Tunnel:

npx @ory/cli tunnel --dev <http://localhost:3000>

- You can find more details [here](https://www.ory.sh/docs/getting-started/integrate-auth/react). 4. Go to production: - To connect the application to your Ory project, the app and Ory APIs must be available under the same common domain, for example

<https://ory.example.com>

and

<https://www.example.com>

. - Add a Custom Domain to your Ory Network project. - Use the configured custom domain in your SDK calls:

// For Go      c := ory.NewConfiguration()        c.Servers = ory.ServerConfigurations{{URL: "<https://ory.example.org>"}}         // For React      var sdk = require("@ory/client")        var ory = new sdk.FrontendApi(        new sdk.Configuration({        basePath: "<https://ory.example.org>",        baseOptions: {        // Ensures that cookies are included in CORS requests:        withCredentials: true,        },        }),        )

- You can find more details [here](https://www.ory.sh/docs/getting-started/integrate-auth/go) and [here](https://www.ory.sh/docs/getting-started/integrate-auth/expressjs). Please note that all authentication requests should go through the backend, no direct request to Ory Network should be made by the client.
