create_invoiceSend a Luxembourg B2B electronic invoice over the Peppol network in Peppol BIS 3.0 / EN 16931 format via Storecove (a certified Peppol Access Point). Luxembourg has mandated structured e-invoicing over Peppol for B2G since 2023 (fully in force), and B2B e-invoicing is expected to be legislated around 2026. Builds the structured invoice JSON from seller + buyer (name, Luxembourg VAT LUxxxxxxxx, address) and line items (description, quantity, net unit price, VAT rate 17/14/8/3/0), computes the Luxembourg VAT breakdown, and submits it under YOUR OWN Storecove credentials. Bring your own credential as header x-storecove-key. You must also pass seller_legal_entity_id — the legalEntityId of the sender you created in your Storecove account. Luxembourg VAT rates: 17 (standard), 14 (intermediate), 8 (reduced), 3 (super-reduced), 0 (zero-rated/exempt/reverse charge). Amounts in EUR. Delivery over Peppol is asynchronous: this returns a submission guid — use get_delivery_evidence with it to fetch the delivery proof/status. Tip: call check_recipient first to confirm the buyer is reachable on Peppol. There is no cancel over Peppol: to reverse an invoice you issue a credit note (a new invoice).
check_recipientCheck whether a business can receive electronic invoices on the Peppol network before you send (Storecove POST /discovery/receives). This is the safe pre-flight for Luxembourg B2B: pass the recipient identifier and scheme and learn if they are a registered Peppol participant. For Luxembourg use scheme 9938 with the VAT number LUxxxxxxxx. Returns can_receive=true when the party is reachable (Storecove code OK). If can_receive is false, the recipient is not on Peppol — fall back to recipient_email in create_invoice or ask them to register.
get_delivery_evidenceFetch the delivery evidence for an invoice sent by create_invoice, using its submission guid (Storecove GET /document_submissions/{guid}/evidence). Peppol delivery is asynchronous — this returns the proof of what was sent and the delivery status/receipt from the recipient Access Point. Call it shortly after create_invoice and poll until it reports delivery. Safe to call anytime.
