Here, we walk through the simplest possible way to insert an Airkit application into an existing web page using the SDK.

Prepare the Application

Create your application as usual. You do not have to drag and drop a Trigger in to the Triggers section of the Journey Builder, but you do need to make sure that the first Step is associated with a Web Flow:

This is the Web Flow that will be initially displayed in your existing web page.

Toggle over to the Triggers Builder and click on the '+' icon next to the App APIs branch of the Tree. Select Create SDK API from the menu that appears:

Upon creating an SDK API, you will be prompted to define its URL Route. Create a new one by adding subdirectory to the root domain, and then clicking the Create button:

Once created, your new URL Route will be selected automatically from the dropdown list of existing routes:

Under Authentication, make sure Enable CORS is checked:

SDK APIs are automatically come out of the box with a configured SDK endpoint, which is accessible as {{URL_ROUTE}}/sdk, where URL_ROUTE is the URL Route defined in Step 3. There is no need to modify this endpoint, but you should save its full URL for future reference as the SDK_API_URL.
Toggle over Settings. Under Integrations, you should see that your API resource is properly configured:

Under Target Host Names, add the root URL of the web page you intend to add your application to:

Save and publish your application.

Configuring your Website

Add following block of HTML to your existing web page after replacing SDK_API_URL with the endpoint configured earlier in the Triggers Builder:

<html>
  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta charset="utf-8" />
    <title>Airkit web SDK</title>
  </head>
  <body>
    <div id="airkit-sdk"></div>
    <script src="https://client.airkit.com/websdk/1.0/airkit_sdk.js"></script>
    <script>
      const sdk = new window.AirkitWebSDK({ renderMode: "inline" })
      sdk.render({ url: SDK_API_URL }) 
    </script>
  </body>
</html>

Note that the endpoint must be given as a string:

<html>
  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta charset="utf-8" />
    <title>Airkit web SDK</title>
  </head>
  <body>
    <div id="airkit-sdk"></div>
    <script src="https://client.airkit.com/websdk/1.0/airkit_sdk.js"></script>
    <script>
      const sdk = new window.AirkitWebSDK({ renderMode: "inline" })
      sdk.render({ url: "https://app.airkit.com/sdk-example/sdk"}) 
    </script>
  </body>
</html>

Ship your changes and view your existing web page. Your Airkit application should appear within it.
