• Make sure before using the ui-api in apex, your Salesforce instance URL is saved in remote site settings
• Get the list view id from url and pass it to apex and directly hit the ui-api with the list view id For example : String sfdcURL = URL.getSalesforceBaseUrl().toExternalForm(); String restAPIURL = sfdcURL + ‘/services/data/v51.0/ui-api/list-info/00B5g00000MNw7FEAT’;
• Get the list view id from url and query the list view name + the sobject name from ListView Object and pass it to the ui-api in apex For example : String sfdcURL = URL.getSalesforceBaseUrl().toExternalForm(); String restAPIURL = sfdcURL + ‘/services/data/v51.0/ui-api/list-info/Opportunity/Test_List_View’;
• Recent List View comes under Search Layouts so to update the fields for that you need to update the search layouts under the particular object
• Using this we can fetch fields of those list view also which are only visible to me
• After getting response you can parse it to use.

//Make sure your Salesforce instance URL is added in remote site settings

String sfdcURL = URL.getSalesforceBaseUrl().toExternalForm();
String restAPIURL = sfdcURL + ‘/services/data/v51.0/ui-api/list-info/Opportunity/Test_List_View’;
