REST api call javascript issue

Hi, recently, I met the issue that when I have a REST call, I didn't get the return value(checkApprovedShippingAddress), I assume it is related to async javascript, please advise.

if(checkApprovedShippingAddress(formContext)){
  alert("1")
}


function checkApprovedShippingAddress(formContext){
debugger;
var currentId = formContext.data.entity.getId();
var query = "ont_shippingaddresses?$select=ont_name,ont_antigenscreeningprogram&$filter=statuscode eq 122290000 and _ont_antigenscreeningprogram_value eq  '" currentId "'"
callAPI(query,function(data){
if(data.value.length > 0){
return true
}
else
{return false}
})
}


function callAPI(query, callback) {
    var globalContext = Xrm.Utility.getGlobalContext();
    var serverUrl = globalContext.getClientUrl();
    //var ODataPath = serverUrl   "/XRMServices/2011/OrganizationData.svc";
    var ODataPath = serverUrl   "/api/data/v9.1/";

    var req = new XMLHttpRequest();
    req.open("GET", ODataPath   query, true);
    req.setRequestHeader("OData-MaxVersion", "4.0");
    req.setRequestHeader("OData-Version", "4.0");
    req.setRequestHeader("Accept", "application/json");
    req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
    req.setRequestHeader("Prefer", "odata.include-annotations=\"*\"");
    req.onreadystatechange = function () {
        if (this.readyState === 4) {
            req.onreadystatechange = null;
            if (this.status === 200) {
                var result = JSON.parse(this.response);
                callback(result);
            } else {
                alert(this.statusText);
            }
        }
    };
    req.send();
}
