SdI / FatturaPA XML

POST /wp-json/api/v2/create-xml generates FatturaPA / SdI XML from the shared POP payload.

What you need

• a valid data payload, authenticated license enabled
• if present on both sides, the payload’s tax_regime must match the account’s
• recipient routing via transmitter_data.sdi_code or transmitter_data.recipient_pec

Output

• success: raw XML
• error (validation, quota, webhook, integration): structured JSON

Delivery

Generated XML can be sent to active SdI integrations or to configured webhooks.

Good to know

• purchase_order_data.id adds DatiOrdineAcquisto
• credit notes require connected_invoice_data.id and date
• in sandbox, invoice_number is prefixed with SANDBOX-
• connector_exclusive_channel_active (403) — SdI delivery is blocked while Zoho is the account’s active, connected billing channel; local XML generation is not affected
• country_not_eligible_for_sdi — the account’s registered country is not IT or SM
• generating and sending via WordPress, direct API, n8n, or MCP no longer requires a paid plan: every plan, including Free, can send using its own available credits. On Shopify, sending still requires the Basic plan or higher
