SharePoint 2013 Rest Api - How to get List Items

Question

 
Can anyone let me know why the below method fails? I am not getting where i am making mistake. Please help
function getListItems(term) {
            var caml = "<View><Query><Where><BeginsWith><FieldRef Name=Title/><Value Type='Text'>" + term + "</Value></BeginsWith></Where></Query></View>";
            var requestData = { "query": { "__metadata": { "type": "SP.CamlQuery" }, "ViewXml": caml } };
            $.ajax({
                url: _spPageContextInfo.webAbsoluteUrl + "/_api/Web/Lists/getbytitle('SampleList')/Getitems",
                method: "POST",
                data:requestData,
                headers: {
                    "accept": "application/json; odata=verbose",
                    "content-type": "application/json; odata=verbose"
                success: function (data) {
                    $("#countItem").html("Pass");
                error: function (data) {
                    $("#countItem").html("Fail");
Below is the responseText (log)
"{\"error\":{\"code\":\"-1, Microsoft.SharePoint.Client.ClientServiceException\",\"message\":{\"lang\":\"en-US\",\"value\":\"The HTTP method \'GET\' cannot be used to access
the resource \'GetItems\'. The operation type of the resource is specified as \'Default\'. Please use correct HTTP method to invoke the resource.\"}}}"

Finally executed successfully using below code. The learning is we need to use  type:"POST" instead of method:"POST"
 function getListItems(term) {
            var urltest = _spPageContextInfo.webAbsoluteUrl + "/_api/Web/lists/getByTitle('SampleList')/getitems(<Query><Where><BeginsWith><FieldRef">query=@v1)?@v1={\"ViewXml\":\"<View><Query><Where><BeginsWith><FieldRef
Name='Title'/><Value Type='Text'>" + term + "</Value></BeginsWith></Where></Query><RowLimit>1</RowLimit></View>\"}";
            $.ajax({
                url: urltest,
                type: "POST",
                headers: {
                    "X-RequestDigest": $("#__REQUESTDIGEST").val(),
                    "Accept": "application/json; odata=verbose",
                    "Content-Type": "application/json; odata=verbose"
                contentType: 'application/json',
                success: function (data) {
                    if (data.d.results.length != 1) {
                        $("#countItem").html("Pass");
                        $("#" + term).parent().parent().prop('disabled', true);
                        $("#" + term).removeAttr("onclick");
                        $("#" + term).css('cursor', 'default');
                        $("#" + term).parent().unbind("mouseenter mouseleave");
                error: function (data) {
                    $("#countItem").html(urltest);
