Google Maps API: No 'Access-Control-Allow-Origin' header is present on the requested resource

I've seen this question asked by multiple people, none of the answers have worked for me.

I'm trying to make an API call to the google maps api with react/axios.

This is my get request:

componentDidMount() {
   method : 'get',
   url : `${key}/`,
   headers: {
     "Access-Control-Allow-Origin": '*'
     "Access-Control-Allow-Methods": 'GET',
 .then(function (response) {
 .catch(function (error) {

This is the error msg:

XMLHttpRequest cannot load
key=xxxxxxxxx/. Response to preflight request doesn't pass access control 
check: No 'Access-Control-Allow-Origin' header is present on the 
requested resource. Origin 'http://localhost:3000' is therefore not allowed access.

I've read the article con CORS that everyone else points to

but I can't find an answer to my problem there. doesn’t support getting requests from frontend JavaScript running in web apps in the way your code is trying to use it.

Instead you need to use the supported Google Maps JavaScript API, the client-side code for which is different from what you’re trying. A sample for the Distance Matrix service looks more like this:

  var service = new google.maps.DistanceMatrixService;
    origins: [origin1, origin2],
    destinations: [destinationA, destinationB],
    travelMode: 'DRIVING',
    unitSystem: google.maps.UnitSystem.METRIC,
    avoidHighways: false,
    avoidTolls: false

<script async defer

And here’s an example for using the Place Autocomplete API using the Places library:

  function initMap() {
    var map = new google.maps.Map(document.getElementById('map'), {
      center: {lat: -33.8688, lng: 151.2195},
      zoom: 13
    var autocomplete = new google.maps.places.Autocomplete(input);
    autocomplete.bindTo('bounds', map);
    var infowindow = new google.maps.InfoWindow();
    var infowindowContent = document.getElementById('infowindow-content');
    var marker = new google.maps.Marker({
      map: map,
      anchorPoint: new google.maps.Point(0, -29)
  async defer></script>

Using the Maps JavaScript API like that—by way of a script element to load the library, and then using the google.maps.Map and other google.maps.* methods—is the only supported way to make requests to the Google Maps API from frontend JavaScript code running a browser.

Google intentionally doesn’t allow access to the Google Maps API by way of requests sent with axios or AJAX methods in other such libraries, nor directly with XHR or the Fetch API.
