Documentation

I need to get an array at the output that I can use in the swagger.yaml file. There can be any number of vacancies

{
    "data": {
        "vacancies": [
            {
                "vacancy_id": "B72",
                "title": "Russia country department",
                "department": "K",
                "location": "Russia",
                "url": "https://example.com/url/199"
            },
            {
                "vacancy_id": "B32",
                "title": "Ukraine country",
                "department": "D",
                "location": "Ukraine",
                "url": "https://example.com/url/175"
            },
            ...
        ]
    }
}
