Vertopal API uses the Bearer authentication scheme (also called token authentication) for authentication and authorization. To begin, obtain client credentials by creating an APP.
Before your application sends requests to the Vertopal API, you must obtain an app ID and an access token that grants access to the API. To authenticate each request, you must put the app ID in its
app data key, and send an access token by the Authorization header along with the request.
If you didn't get an error and everything goes well, you will be connected to the Vertopal API.
