Sending

Send raw UBL

For callers who already generate compliant PINT OM UBL themselves.

For callers who already generate compliant PINT OM UBL and want to skip the JSON-to-UBL build step that Create an invoice handles. You keep control of the document; you also take on responsibility for keeping it compliant as the Oman specification evolves. Once accepted, the same tracking and webhook model applies — see Get a transaction.

POST/v1/api/documents
returns 202
FieldType Description
sender_iduuidrequiredThe taxpayer issuing the document
documentstringrequiredThe complete UBL XML, as a JSON string
receiver_schemestringoptionalPeppol scheme, e.g. 0248. Read from the document if omitted
receiver_idstringoptionalReceiver identifier. Read from the document if omitted
metadataobjectoptionalYour own key–value pairs, returned unchanged on the transaction
webhook_urlstringoptionalOverride your registered webhook for this document only

You don't declare the profile. SUMU reads it from the document — the root element, the CustomizationID and the type code together determine which Oman rule set applies. Declaring it yourself would let a mismatch pass validation here and be refused by the receiving Access Point, so it's resolved rather than trusted. profile and document_type_code are echoed back on the response so you can confirm the document was interpreted as intended.
