Adobe plug-in: getQueryParam


This plug-in is provided by Adobe Consulting as a courtesy to help you get more value out of Adobe Analytics. Adobe Customer Care does not provide support with this plug-in, including installation or troubleshooting. If you require help with this plug-in, contact your organization’s Account Manager. They can arrange a meeting with a consultant for assistance.

The getQueryParam plug-in allows you to extract the value of any query string parameter contained in a URL. It is useful for extracting campaign codes, both internal and external, from landing page URLs. It is also valuable when extracting search terms or other query string parameters.

This plug-in provides robust features in parsing complex URLs, including hashes and URLs containing multiple query string parameters. If you only have simple query string parameter needs, Adobe recommends using the URL parameter features using the Web SDK or the Adobe Analytics extension or the Util.getQueryParam() method included in AppMeasurement.

Install the plug-in using custom code editor

If you do not want to use the plug-in extension, you can use the custom code editor.

  1. Log in to Adobe Experience Platform Data Collection using your AdobeID credentials.
  2. Click on the desired property.
  3. Go to the Extensions tab, then click the Configure button under the Adobe Analytics extension.
  4. Expand the Configure tracking using custom code accordion, which reveals the Open Editor button.
  5. Open the custom code editor and paste the plug-in code provided below into the edit window.
  6. Save and publish the changes to the Analytics extension.

Use the plug-in

The getQueryParam function uses the following arguments:

  • qsp (required): A comma delimited list of query string parameters to look for within the URL. It is not case-sensitive.
  • de (optional): The delimiter to use if multiple query string parameters match. Defaults to an empty string.
  • url (optional): A custom URL, string, or variable to extract the query string parameter values from. Defaults to window.location.

Calling this function returns a value depending on the above arguments and the URL:

  • If a matching query string parameter is not found, the function returns an empty string.
  • If a matching query string parameter is found, the function returns the query string parameter value.
  • If a matching query string parameter is found but the value is empty, the function returns true.
  • If multiple matching query string parameters are found, the function returns a string with each parameter value delimited by the string in the de argument.


// Given the URL
// Sets the campaign variable to "trackingcode"
s.campaign = getQueryParam('cid');

// Given the URL
// Sets the campaign variable to "trackingcode:123"
s.campaign = getQueryParam('cid,ecid',':');

// Given the URL
// Sets the campaign variable to "trackingcode123"
s.campaign = getQueryParam('cid,ecid');

// Given the URL
// Sets the campaign variable to "123"
s.campaign = getQueryParam('ecid');

// Given the URL
// Sets the campaign variable to "123"
// The plug-in replaces the URL's hash character with a question mark if a question mark doesn't exist.
s.campaign = getQueryParam('ecid');

// Given the URL
// Does not set the campaign variable to a value.
s.pageURL = "";
s.campaign = getQueryParam('cid');

// Given the URL
// Sets the campaign variable to "trackingcode"
s.pageURL = "";
s.campaign = getQueryParam('cid','',s.pageURL);

// Given the URL
// Sets eVar2 to "123|trackingcode|true|300"
s.eVar1 = "";
s.eVar2 = getQueryParam('ecid,cid,location,pos','|',s.eVar1);
