Hi all,

I have two REST calls and need to return the values that match (ex. If the first REST call output produces an array of 1, 2, 3... I want to the second REST call to output the values that match 1, 2, 3.)

My data looks something like this:

- Data source 1 accessed by REST call 1 has a field named PostCategoryID. This field can contain multiple values

- Data source 2 accessed by REST call 2 has two fields, one named ID and another named Title. The ID in list matches the value(s) in the PostCategoryID field of data source 1.

I need to output the Title from data source 2 where it matches data source 1.

Currently it displays all the Titles from data source 2, not just the ones I am trying to match against.

Here is my code. Please assist and thanks in advance:

1. function yourcompanyNews()
   {
       var basePath = "/sites/resourcecenter/news/_api/";
       $.ajax({
           async: false,
           url: basePath + "web/lists/GetByTitle('Posts')/items?$filter=Placement eq 'YourCompany News'&$top=5&$orderby=YourCompanyNewsOrder asc",
           type: "GET",
           headers: { "Accept": "application/json;odata=verbose" },
           success: function (data)
           {
               //script to build UI HERE
               $.each(data.d.results, function (index, value)
               {
                   blogPostID = value.ID
                   categoryID = value.PostCategoryID
                   $("#YourCompanyNews").append('<p><a href="/sites/resourcecenter/news/Lists/Posts/Post.aspx?ID=' + blogPostID + '">' + value.Title + '</a>' + '</br>' + value.Placement + '</br>' + '<img src="' + value.Thumbnail.Url + '" /></p><p id="BlogPost' + blogPostID + '"></p>');
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
2.                 $.ajax({
                       async: false,
                       url: "https://yourcompany.com/sites/resourcecenter/news/_api/web/lists/GetByTitle('Department or Region')/items",
                       type: "GET",
                       headers: { "Accept": "application/json;odata=verbose" },
                       success: function (categories) {
                           //script to build UI HERE
                           $.each(categories.d.results, function (index, value) {
                               if ($.inArray(value.ID, categoryID)) {
                                   $('#BlogPost' + blogPostID).append(value.Title);
                               }
                           });
                       },
                   });
               });
           },
           error: function (data)
           {
               //output error HERE
               alert(data.statusText);
           },
           error: function (data) {
               //output error HERE
               alert(data.statusText);
           },
           });
   }
