I try to implement Amadeus hotel booking API.
But it always return error, on both V1 and V2.

here is the detail

V1
https://test.api.amadeus.com/v1/booking/hotel-bookings
body

{
  "data": {
    "offerId": "{{hotelOfferId}}",
    "guests": [
      {
        "id": 1,
        "name": {
          "title": "MR",
          "firstName": "BOB",
          "lastName": "SMITH"
        },
        "contact": {
          "phone": "+33679278416",
          "email": "[email protected]"
        }
      }
    ],
    "payments": [
      {
        "id": 1,
        "method": "creditCard",
        "card": {
          "vendorCode": "VI",
          "cardNumber": "4111111111111111",
          "expiryDate": "2026-08"
        }
      }
    ],
    "rooms": [
      {
        "guestIds": [
          1
        ],
        "paymentId": 1,
        "specialRequest": "I will arrive at midnight"
      }
    ]
  }
}

response

{
    "errors": [
        {
            "code": 38190,
            "title": "Invalid access token",
            "detail": "The access token provided in the Authorization header is invalid",
            "status": 401
        }
    ]
}

I already logged in, and no problem with another endpoints.

                    {

                    }
                ],
                "hotelOfferId": "{{hotelOfferId}}"
            }

Thank you for your response, it is very meaningful for me.

I read the documentation, and try the official postman. But it’s all not helping.
