    Quickstart - API Request



    Postmessage postMessage is a browser API that you need to work with while using Stellantis Embedded Webportal for ex Groupe PSA brands (Citroën, DS, Peugeot, Opel and Vauxhall).

    As your App is a dedicated Window object, postMessage is a way to communicate with webportal. Doing so, you’re app is able to request info about the vehicle as well as sending data to it!

    Here is a typical postMessage that you need to send to webportal in order to communicate with the vehicle:

    var requestId = generateRandomId();
    parent.postMessage('*', {
        "id": requestId,
        "type": "GET",
        "api": "configuration.VIN",
        "params": null
