Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

acube

acube_create_draft_invoice

WRITE: saves a new invoice as a DRAFT in A-Cube. Nothing is sent to the SDI until acube_send_draft_invoice. Not idempotent: calling it twice creates two drafts. Validate first with acube_validate_invoice. POST /invoices/draft.

acube_delete_draft_invoice

WRITE: permanently deletes a draft invoice (a draft only: a sent invoice answers 409). Without confirm: true it only returns the draft. DELETE /invoices/draft/{uuid}.

acube_get_business_registry_configuration

One business by fiscal id: name, email, enabled services and its webhook configurations. GET /business-registry-configurations/{fiscalId}.

acube_get_current_numbering_sequence

The sequence now in use for a sequence name. Its number is the LAST number used: the next invoice gets that number plus one. GET /numbering-sequences/current/{name}.

acube_get_draft_invoice

One draft invoice by uuid, with its FatturaPA JSON content. GET /invoices/draft/{uuid}.

acube_get_invoice

One invoice by uuid: metadata plus the FatturaPA JSON payload (parties, lines, VAT, payment), or the XML file sent to the SDI. GET /invoices/{uuid}.

acube_get_invoice_stats

Counters of invoices and notifications for a year (annual; monthly or daily detail only if A-Cube activated it), for the whole account or one fiscal id. GET /invoices/stats/{year}.

acube_get_job

One background job by uuid with its status and result. GET /jobs/{uuid}.

acube_get_notification

One SDI notification by uuid, with its payload. GET /notifications/{uuid}.

acube_get_receipt

One electronic receipt by uuid: type, status, number, date, total and links to voiding or returned receipts (no line items: use acube_get_receipt_details). GET /receipts/{uuid}.

acube_get_receipt_details

The line items and VAT, discount and taxable totals of one electronic receipt. GET /receipts/{uuid}/details.

acube_get_recipient_code

The account's 7-character SDI recipient code (codice destinatario), the address customers put on invoices they send to you. GET /users/me/recipient-code.

acube_list_business_registry_configurations

The businesses (fiscal ids) set up on the account, with which services are on: customer invoices, supplier invoices, receipts, signature, legal storage. GET /business-registry-configurations.

acube_list_draft_invoices

Draft invoices that were created but not yet sent to the SDI. Same filters as acube_list_invoices. GET /invoices/draft.

acube_list_invoice_notifications

The SDI notifications of one invoice (delivery receipt RC, rejection NS, outcome NE, failed delivery MC, deadline expiry DT...), with their type, date and status: how you tell whether an invoice was delivered or rejected. GET /invoices/{uuid}/notifications.

acube_list_invoices

Sent and received Italian e-invoices (SDI) of the account: uuid, invoice number and date, document type (TD01...), sender and recipient, amounts, marking and notification status. Filter by date, number, document type, party name or VAT number. GET /invoices.

acube_list_jobs

Background jobs (invoice, report and zip downloads, F24 and daily receipt report downloads) with status ready, started, completed or error. GET /jobs.

acube_list_numbering_sequences

The invoice numbering sequences (name, year, last number). GET /numbering-sequences.

acube_list_receipts

Electronic commercial receipts (scontrini) with number, date, status, type (sale, void, return) and totals. GET /receipts.

acube_list_webhooks

The webhooks (events and target URLs) configured on the account. Authentication keys and tokens are never returned. GET /api-configurations.

acube_send_draft_invoice

WRITE: accepts a draft and transmits it to the Sistema di Interscambio. This is a legal act: a sent e-invoice cannot be recalled (only corrected with a credit note) and may be billed by A-Cube. Without confirm: true it only returns the draft for review. Show the draft to the user and get their explicit OK first. POST /invoices/draft/{uuid}/send.

acube_validate_invoice

Checks an invoice against the FatturaPA rules without creating or sending anything; returns the validation result or A-Cube's errors. POST /invoices/validate.

acube_verify_company

Basic registry data of an Italian company by VAT number (name, address, status), optionally with the split-payment check. GET /verify/company/{id}.

acube_verify_fiscal_id

Checks whether a codice fiscale or partita IVA is valid. GET /verify/fiscal-id/{id}.
