Click Full Window viewing mode, then click the Customize button to toggle options on and off.
Disable Download PDF option.
Click Generate Code button to see the code preview.
Copy Client ID from the Client Credentials window from Part 1.
Open the Web -> resources -> js -> dc-config.js file in your code editor.

You’ll see that the clientID variable is there.
Paste your client credentials between the double quotes to set the clientID to your credential.
Go back to the developer sandbox code preview.

Copy the second line that has the Adobe script:

code language-none
`<script src=https://documentccloud.adobe.com/view-sdk/main.js></script>`

Screenshot of script

Go to your code editor and open the Web -> exercise -> index.html file.
Paste the script code into the <head> of the file on line 18 under the comment that says: TODO: EXERCISE 1: INSERT EMBED API SCRIPT TAG.

Go back to the developer sandbox code preview and copy the first line of code that has:

code language-none
`<div id="adobe-dc-view"></div>`

Screenshot of where to copy code

Go to your code editor and open the Web -> exercise -> index.html file again.
Paste the <div> code into the <body> of the file on line 67 under the comment that says TODO: EXERCISE 1: INSERT PDF EMBED API CODE.

Go back to the developer sandbox code preview and copy the lines of code for the <script> below:

code language-none

code language-none
`<script type="text/javascript"> document.addEventListener("adobe_dc_view_sdk.ready", function(){ var adobeDCView = new AdobeDC.View({clientId: "<YOUR_CLIENT_ID>", divId: "adobe-dc-view"}); adobeDCView.previewFile({ content:{location: {url: "https://documentcloud. adobe.com/view-sdk-demo/PDFs/Bodea Brochure. pdf"}}, metaData:{fileName: "Bodea Brochure.pdf"} }, {showDownloadPDF: false}); }); </script>`

<script type="text/javascript">
    document.addEventListener("adobe_dc_view_sdk.ready",             function(){
        var adobeDCView = new AdobeDC.View({clientId:                     "<YOUR_CLIENT_ID>", divId: "adobe-dc-view"});
        adobeDCView.previewFile({
            content:{location: {url: "https://documentcloud.                adobe.com/view-sdk-demo/PDFs/Bodea Brochure.                    pdf"}},
            metaData:{fileName: "Bodea Brochure.pdf"}
        }, {showDownloadPDF: false});
    });
</script>

Go to your code editor and open the Web -> exercise -> index.html file again.
Paste the <script> code into the <body> of the file on line 68 under the <div> tag.
Modify line 70 of the same index.html file to include the clientID variable that was created previously.
Modify line 72 of the same index.html file to update the location of the PDF file to use a local file.

There is one available in the tutorial files in /resources/pdfs/whitepaper.pdf.
Save your modified files and preview your website by browsing to <your domain>/summit21/web/exercise/.

You should see the Technical Whitepaper render in a Full Window mode within your browser.

Part 3: Accessing Analytics APIs part3

Now that you’ve successfully created a web page that has PDF Embed API rendering a PDF, in part 3 you can now explore how to use JavaScript events to measure analytics to understand how users are using PDFs.

Finding documentation

There are a lot of different JavaScript events available as part of PDF Embed API. You can access them from Adobe Acrobat Services documentation.

Navigate to the documentation site.
Review the different event types available as part of the API. These are helpful for reference and will also be helpful for your future projects.

Copy the sample code listed on the website.

Use this as the basis for our code and modify it.

Screenshot of where to copy sample code

code language-none

code language-none
`const eventOptions = { //Pass the PDF analytics events to receive. //If no event is passed in listenOn, then all PDF analytics events will be received. listenOn: [ AdobeDC.View.Enum.PDFAnalyticsEvents. PAGE_VIEW, AdobeDC.View.Enum.PDFAnalyticsEvents.DOCUMENT_DOWNLOAD], enablePDFAnalytics: true } adobeDCView.registerCallback( AdobeDC.View.Enum.CallbackType.EVENT_LISTENER, function(event) { console.log("Type " + event.type); console.log("Data " + event.data); }, eventOptions );`

const eventOptions = {
  //Pass the PDF analytics events to receive.
   //If no event is passed in listenOn, then all PDF         analytics events will be received.
listenOn: [ AdobeDC.View.Enum.PDFAnalyticsEvents.    PAGE_VIEW, AdobeDC.View.Enum.PDFAnalyticsEvents.DOCUMENT_DOWNLOAD],
  enablePDFAnalytics: true
}


adobeDCView.registerCallback(
  AdobeDC.View.Enum.CallbackType.EVENT_LISTENER,
  function(event) {
    console.log("Type " + event.type);
    console.log("Data " + event.data);
  }, eventOptions
);

Find the code section you added earlier that looks like the below and append the code above after this code in index.html:
Load the page in your web browser, and open the Console to view the console outputs from the different events as you interact with the PDF viewer.

Add switch for capturing events

Now that you have the events being outputted to console.log, let’s change the behavior based on which events. To do this, you’ll use a switch example.

Navigate to snippets/eventsSwitch.js and copy the contents of the file in the tutorial code.
Paste the code in the event listener function.
Confirm that the console outputs correctly when the page is loaded and you interact with the PDF Viewer.

Adobe Analytics

If you want to add Adobe Analytics support to your viewer, you can follow the instructions documented on the website.

IMPORTANT

Your webpage needs to already have Adobe Analytics loaded on the page in the header.

Navigate to the Adobe Analytics documentation and review if you already have Adobe Analytics enabled on your webpage. Follow instructions to set up a reportSuite.

Google Analytics

Screenshot of how to integrate with Google Analytics

Adobe PDF Embed API provides out-of-box integration with Adobe Analytics. However, because all events are available as JavaScript events, it is possible to integrate with Google Analytics by capturing PDF events and using the ga() function to add the event to Adobe Analytics.

Navigate to snippets/eventsSwitchGA.js to see how you can integrate with Google Analytics.
Review and use this code as an example if your webpage is tracked using Adobe Analytics and it is already embedded on the webpage.

Part 4: Add interactivity based on events part4

In part 4, you’ll walk through how to layer on top of your PDF viewer a paywall that shows after you scroll past the second page.

Paywall example

Navigate to this example of a PDF behind a paywall. In this example, you’ll learn to add interactivity on top of a PDF viewing experience.

Add paywall code

Go to snippets/paywallCode.html and copy the contents.
Search for  in exercise/index.html.
Paste the copied code after the comment.
Go to snippets/paywallCode.js and copy the contents.
Paste the code into that location.

Try Demo with Paywall

Now you can view the demo.

Reload index.html on your website.
Scroll down to a page > 2.
Show the dialog come up to challenge user after the second page.
