About OneLink Smart Script

OneLink Smart Script uses incoming URLs leading to the webpage to automatically generate unique outgoing OneLink URLs leading to the app store.

The outgoing URLs are generated using arguments you receive from the marketer and input into the script. Note: The afParameters argument has a structure made up of several other arguments (parameters), each of which contains a configuration object that has keys, override values, and a default value.

Implementation steps

To set up the Smart Script, you can either:

Embed the script in your website

The Smart Script initialization and calling code can be either come from the Smart Script generator in the AppsFlyer dashboard (recommended), or imported and called manually by the developer.

Use code generated by the Smart Script generator

  1. Get the file from the marketer that includes the script, initialization code, and arguments.
  2. Test the script on the Smart Script test page. Ensure the correct outgoing URL is generated.
  3. Follow the test and use Smart Script result instructions.

See integration example in Github

Manually configure the script

  1. Download the script.
  2. Get the arguments to call the script which map the incoming parameters to the outgoing parameters from the marketer.
  3. Initialize the Smart Script arguments and configuration objects.
  4. Generate the URLs by calling the script in the web/landing page HTML using the following method:
var result = window.AF_SMART_SCRIPT.generateOneLinkURL({
  oneLinkURL,
  afParameters,
  referrerSkipList, // optional
  urlSkipList // optional
})
  1. Follow the test and use Smart Script result instructions.

Check and use Smart Script result

  1. Check the return value in result. Possible return values are:
    • An outgoing Onelink URL. Use the result value as needed. For example, to place it as a link under a CTA on your website.
    • null. If the script returns null, implement your desired error flow. For example: the web/landing page's existing URL is not changed.
      var result_url = "No output from script"
      if (result) {
            result_url = result.clickURL;            
            // Put the generated OneLink URL behind CTA buttons
            document.getElementById('andrd_link').setAttribute('href', result_url);
            document.getElementById('ios_link').setAttribute('href', result_url);
            // Optionally - Create QR code from the generated OneLink URL
            window.AF_SMART_SCRIPT.displayQrCode("my_qr_code_div_id");
            //The size of the QR code is defined in the CSS file under #my_qr_code_div_id
            // #my_qr_code_div_id canvas { 
            //  height: 200px;
            //  width: 200px;
            //}
            // Optionally - fire an impression.
            // The impression will fire to https://impressions.onelink.me//.... 
            window.AF_SMART_SCRIPT.fireImpressionsLink();
      }

Use Google Tag Manager

To set up the Smart Script in Google Tag Manager:

  1. Confirm that the marketer followed their instructions and placed the Smart Script code into GTM.
  2. Check the return value in AF_SMART_SCRIPT_RESULT. Possible return values are:
    • An outgoing OneLink URL. Use the result value as needed. For example, to place it as a link under a CTA on your website.
    • null. If the script returns null, implement your desired error flow. For example: the web/landing page's existing URL is not changed.
      var result_url = AF_SMART_SCRIPT_RESULT.clickURL;
      if (result_url) {
            document.getElementById('andrd_link').setAttribute('href', result_url);
            document.getElementById('ios_link').setAttribute('href', result_url);
            // Optionally - Create QR code from the generated OneLink URL
            window.AF_SMART_SCRIPT.displayQrCode("my_qr_code_div_id");
            //The size of the QR code is defined in the CSS file under #my_qr_code_div_id
            // #my_qr_code_div_id canvas { 
            //  height: 200px;
            //  width: 200px;
            //}
            // Optionally - fire an impression.
            // The impression will fire to https://impressions.onelink.me//.... 
            window.AF_SMART_SCRIPT.fireImpressionsLink();            
      }
  1. Test the script on the Smart Script test page. Ensure the correct outgoing URL is generated.

Create a QR code with the Smart Script result

Prerequisite: Smart Script V2.1+

To create a QR code:

  1. Create a div tag with a specific ID in your site's HTML page to host the QR code.
    You can style the div tag however you want.
  2. After you run the Smart Script and generate a OneLink URL, call the following function and pass it the div ID:
window.AF_SMART_SCRIPT.displayQrCode("my_qr_code_div_id");
  1. Best practice: Once you have the result, show the QR code when users are on desktop and show the button with the link when users are on mobile.

Fire an impression

You can fire an impression when a page loads, a CTA or banner displays, etc. Note: Impressions can only be fired on mobile devices; not on desktop.

Prerequisite: Smart Script V2.2+

To fire an impression:

  1. Follow the instructions to run the Smart Script and generate a click URL.
  2. Make sure the result is valid (and not null).
  3. Run the following impression function:
window.AF_SMART_SCRIPT.fireImpressionsLink();

Configuration object

The OneLink Smart Script uses arguments to generate an outgoing URL based on the parameters of the incoming URL and the arguments defined in the script. The afParameters argument has a structure made up of several other arguments (parameters) used for attribution and deep linking, each of which contains a configuration object that has keys, override values, and a default value, as described in the table that follows.

Argument Description Example
keys
  • List of strings
  • List of possible parameter/s in the incoming URL the script looks for, the value of which is placed as the value in the outgoing URL.
  • The script searches from left to right and stops at the first match.
  • Example: ['in_channel', 'utm_channel']
  • For the channel parameter in the script, the script searches the incoming link for in_channel and uses the value as the value for channel.

overrideValues
  • Dictionary {string: string}
  • For values you want changed in the outgoing link, list the values in the incoming URL, alongside what you want them to be replaced with.
  • The script replaces the param values of the incoming URL with the values you define. 

Example: {'video': 'video_new'}

For the channel parameter in the script, anytime the incoming value is video, the script changes it to video_new on the outgoing link.

defaultValue
  • String
  • State what you want your "fallback" value to be.
  • If a parameter is not found from your key list, the defaultValue value is used in the outgoing URL.
  • You can force a default value by passing an empty keys list.

Example: ['web_video']

For the channel parameter in the script, if you have the param in_channel is not found, web_video is used as the channel value.
