Trouble in API Calling [closed]

// Initialize and add the map
function initMap() {
    // Map options
    var mapOptions = {
        center: { lat: 28.618846, lng: 77.284942 },
        zoom: 12
    };

    // Create a map object
    var map = new google.maps.Map(document.getElementById("map"), mapOptions);

     // Fetch the coordinates and addresses from the API
     fetch("http://inventorysoftware.co.in/api/Users/FetchtrackingbyDate")
    .then(response => response.json())
    .then(data => {
        const locations = data.locations; // Assuming the API response contains an array of locations

        // Iterate over each location
        locations.forEach(location => {
            // Create marker for each location
            var marker = new google.maps.Marker({
                position: { lat: location.lat, lng: location.lng },
                map: map,
                title: location.title
            });

            // Create info window content
            var infoWindowContent = '<div><strong>' + location.User + '</strong><br>' +    

            location.address + '</div>';

            // Create info window
            var infoWindow = new google.maps.InfoWindow({
                content: infoWindowContent
            });

            // Add click event listener to open info window when marker is clicked
            marker.addListener('click', function () {
                infoWindow.open(map, marker);
            });
        });

        // Extract coordinates for route polyline
        var routeCoordinates = locations.map(location => ({
            lat: location.lat,
            lng: location.lng
        }));

        // Create a Polyline to represent the route
        var routePath = new google.maps.Polyline({
            path: routeCoordinates,
            geodesic: true,
            strokeColor: "#87CEEB",
            strokeOpacity: 1.0,
            strokeWeight: 2
        });

        // Set the Polyline on the map
        routePath.setMap(map);

        // Set the map bounds to include all route coordinates
        var bounds = new google.maps.LatLngBounds();
        routeCoordinates.forEach(coord => {
            bounds.extend(coord);
        });
        map.fitBounds(bounds);
    })
    .catch(error => console.error('Error fetching data from API:', error));
}

I tried to show the Employee location on map. But API is not working. No Get Method. Implemented the POST Method where when you POST enter date and companyid in json format, it will return data.
