Our Tile Services integrates easly with Mapbox. You only need to tell Mapbox to put the x-client-id header on the request. To do that, you can use transformRequest in your Mapbox constructor.
Here is a snippet to give you an idea of how this will look when we combine everything together;
var map = new mapboxgl.Map({ container: 'map', center: [-122.420679, 37.772537], zoom: 13, transformRequest: (url, resourceType)=> { if(resourceType === 'Tile' && url.startsWith('https://api-2.chargetrip.io')) { return { url: url, headers: { "x-client-id": "YOUR_CLIENT_ID_HERE" }, } } }});
