Microsoft Dynamics Nav API Error: Customer Posting Group must have a value in Customer

Question

I have some trouble with API method for posting order info into 'API for Dynamics 365 Business Central'.

So in official doc about order says for create order you must add 'Customer Info' to the request body. Before that you must create Customer(doc for customer).

But if i try to create order with info from Customer request, i have error:

Error: "Application_FieldValidationException","message":"Customer Posting Group must have a value in Customer"

So main question is: How to create(or get) and set Posting Group into Customer request?

Or if it wrong way, how to do this right?

Answer 1

You can call a codeunit that creates the customer by passing some parameters to this codeunit, but if you use a POST to the customer API you cannot call the setup in the body. The request body needs the JSON object.

You can't create customer ready for posting via API. Creating a customer ready for posting (with all posting setup) is something that should do by an interanl user (administrative/financial department) and not by an API.

The API can create the basic customer card, but posting groups and so on could depend on different administrative parameters that you could not always know.
