Does the Sage X3 ERP have a REST API that I can use to create a new purchase order with download a list of all existing customers in the ERP? This seems like a very basic question, but neither Google nor the official documentation at https://developer.sage.com/x3/ answers it. The official docs say X3 has: a GraphQL API a SOAP API, that looks incomplete, that is, only covering a small part of the functionality of Sage APIs for file-based integration or import/export Can you help me with that?
