This means that any GET or POST request over /v1/payments will be giving a response like the following:


    "payer": {
        "type": null,
        "id": 12345,
        "email": null,
        "identification": {
            "type": null,
            "number": null
        "phone": {
            "area_code": null,
            "number": null,
            "extension": null
        "first_name": null,
