How to use the einvoice API to import UBL invoices

Use the eInvoice API to create new invoices in Proactis using the UBL message standard.

UBL 2.1​

Proactis eInvoice API uses the UBL message standard. We suggest you refer to the UBL 2.1 website to learn more. Sample messages including annotation can be found on the sample messages page.

Import invoices into Proactis​

Invoices created in a different application and required for other processes in Proactis can be imported using the Proactis API. Individual invoices can be send to Proactis using a POST request containing a UBL 2.1 version of the invoice. Each invoice requires at least one invoice line item. The API will respond with a UBL response, further processing and its status will be visible in the eInvoicing widgets.

More information on the process can be read here.
