Question

Swift

Good afternoon!

Please tell me how to work with the API, where is the authorization through Basic Auth? There are no problems with the usual API, but I don’t know about this one, there is data:
Authorization:
Accept-Language: ru_RU
Content-Type: application/json

I don’t know how and where to register!
