Multiple Tax IDs and Registration Types
In some cases, you may need to send multiple Tax IDs in a single request.
To do so, you can add a list like this:
{
"saleMessageType": "QUOTATION",
"deliveryTerm": "SUP",
"customer": {
"customerCode": {
"value": "customer1"
},
"customerName": "Swatch",
"destination": {
"country": "CH"
},
"taxRegistrations": [
{
"isoCountryCode": "GB",
"taxRegistrationNumber": "XI726490424"
},
{
"isoCountryCode": "CH",
"taxRegistrationNumber": "CHCHE-101.374.515",
"taxRegistrationType": "VAT Registration"
},
{
"isoCountryCode": "PL",
"taxRegistrationNumber": "will-not-be-validated",
"taxRegistrationType": "VAT Registration",
"validationResult": {
"isValid": true
}
}
]
},
