To get all of the parameters available in the request object, and their values:

<syntaxhighlight lang="java" enclose="div">

<%

 String[] params = request.getParameterValues();
 for (int i=0; i<params.length; i++)
 {
   String paramName = params[i];
   String paramValue = request.getParameter( paramName );
 }

%> </syntaxhighlight>

To obtain a record identifier from a request object sent by the platform:

<syntaxhighlight lang="java" enclose="div">

<%

 String object_id = request.getParameter("object_id");
 String record_id = request.getParameter("record_id");

%> </syntaxhighlight>

Note: Although the object_id is alphanumeric, it can be used in any API that requires an object name.

To obtain a record identifier from a request object sent by a Custom Action button:

A Custom Action button can be applied to one record, or to several records at one time, if the user took advantage of the More Actions feature in the record list view. Because it can be applied to more than one record at a time, the process for obtaining record IDs differs somewhat.

Here is the code that does the job:

<syntaxhighlight lang="java" enclose="div">

<%

 // Get the object ID and the comma separated list of record IDs
 String object_id = request.getParameter("object_id");
 String selectedRecords = request.getParameter("selectedRecords"); 
 // Break the comma-separated list into record IDs. 
 // Join them with "OR" operands for use when doing a search for the records
 String filterCriteria = "";
 if (selectedRecords != null)
 {
   StringTokenizer st = new StringTokenizer(selectedRecords,",");
   while (st.hasMoreTokens())
   {
     if ( !"".equals(filterCriteria.trim()))
     {
       filterCriteria = " OR "
     }
       filterCriteria += "record_id = "+ st.nextToken();
   }
 }
 // Use the filter criteria to fetch the selected records
 // Here, we ask for the record_id and name fields
 Result results;
 results = Functions.searchRecords(object_id , "record_id,name", filterCriteria);
 int resultCode = results.getCode();
 if (resultCode < 0)
 {
    // Error occurred
 }
 else if (resultCode == 0)
 {
   // No records found. (This situation should never occur.)
 }
 else
 {
   // Records retrieved successfully
   // Process them here
   ParametersIterator iterator = results.getIterator();
   while(iterator.hasNext())
   {
     Parameters params = iterator.next();
     String recordID = params.get("record_id");
     String recordName = params.get("name");
     // Take additional action according to your business logic
   }
 }
