Hi Magnus, Auto-correction takes place in the address section on two tabs: "General Information" and "Invoicing settings". On the tab "Delivery settings" all looks correct (I mean there is no auto-correction). ... View more

Hi Yıldırım, In the config that you specified I removed all the ticks for validation of customer data.   And tried to again send the following data for creating a new customer:     { "name":{ "value":"Andrii Bilka" }, "accountReference":{ "value":"65213" }, "customerClassId":{ "value":"4" }, "mainAddress":{ "value":{ "addressLine1":{ "value":"Leiknesveien 68" }, "postalCode":{ "value":"9357" }, "city":{ "value":"Finnsnes" }, "countryId":{ "value":"NO" }, "county":{ "value":"1029" } } }, "mainContact":{ "value":{ "name":{ "value":"Andrii Bilka" }, "attention":{ "value":"Andrii Bilka" }, "email":{ "value":"andrii.bil@gmail.com" } } }, "invoiceAddress":{ "value":{ "addressLine1":{ "value":"Leiknesveien 68" }, "postalCode":{ "value":"9357" }, "city":{ "value":"Finnsnes" }, "countryId":{ "value":"NO" }, "county":{ "value":"1029" } } }, "invoiceContact":{ "value":{ "name":{ "value":"Andrii Bilka" }, "attention":{ "value":"Andrii Bilka" }, "email":{ "value":"andrii.bil@gmail.com" } } }, "deliveryAddress":{ "value":{ "addressLine1":{ "value":"Leiknesveien 68" }, "postalCode":{ "value":"9357" }, "city":{ "value":"Finnsnes" }, "countryId":{ "value":"NO" }, "county":{ "value":"1029" } } }, "deliveryContact":{ "value":{ "name":{ "value":"Andrii Bilka" }, "attention":{ "value":"Andrii Bilka" }, "email":{ "value":"andrii.bil@gmail.com" } } } }     And received the following result: As you can see from the screen, on the tabs that I marked with red arrows, county is automatically corrected and don't correspond to the one that I sent in JSON. On the tab marked with a green arrow all corresponds to what I sent. Also, please notice that except for county, city (Sted in Norwegian) is also corrected. In the example that you showed it happens as well. So the question is: why this corrections might take place despite they are disabled in the configurations? Can we expect in the future that for county validation there will be a separate checkbox in settings so that we have a possibility to separately enable validation for postcode and for county? ...
