Interoperability tests
To get the tax connector to communicate with the SDI webservice and for the SDI webservice to communicate with the Italian Tax Connector’s webservice, a series of Interoperability tests must be performed. These tests run through all points of communication, even though some may not be required for your specific installation.
When you register with SDI, you will receive three destination codes. You need to send an invoice to each destination. In effect, you are sending sales invoices out to yourself and you will receive one response and two supplier invoices back. The supplier invoices can be found in the inbox folder of the tax connector. When you receive the supplier invoices, you must accept one and reject the other.
The data in the XML you send and receive mean that most of the ten tests below are tested:
