Send UBL to Peppol

This API allows to include the UBL file and send it via Open/Peppol.

Goal of this API endpoint:

The sender is able to deliver a valid Peppol UBL file : the file complies with the Open/Peppol validation rules and the customer and supplier are correctly mentionned. During setup the sender will test that the UBL is valid for all invoicing scenario's.
The transport type is Open/Peppol. Other email networks and sending via Email are not covered by this endpoint.
The MyBillit User Interface is not used for manual tracking the success of the delivery. Status is obtained via API and can be inserted into the software of the sender.

The UBL file will be included in the Json body.

Below 2 examples:

first one is UBL excluding encoded object
second one is UBL inclucing encoded object (PDF attachment) - to be added

All structured ID's (schemeID, unit codes, currency ID's) get a backslash before and after the value. They are marked in color in the sample file below.
