fiscalo

fiscalo_add_document_line

Add a line to a draft document. Only drafts accept lines; issued documents return document_not_editable. A retry adds the line again: check the document first. Fiscalo API: POST /documents/{id}/lines.

fiscalo_connection_test

Check that the API key works and show its environment (sandbox or production). Use this first. Fiscalo API: GET /connection-test.

fiscalo_create_customer

Create a customer (individual or company). Writes need production access on the company. Fiscalo API: POST /customers.

fiscalo_create_document_draft

Create a draft document for a customer in an active series. The draft is NOT issued: this tool cannot issue or cancel a document. Repeating the same call sends the same Idempotency-Key, so it does not create a second draft. Fiscalo API: POST /documents.

fiscalo_create_item

Create a product or service with its unit price and tax rate. Writes need production access on the company. Fiscalo API: POST /items.

fiscalo_get_customer

Get one customer by its Fiscalo id. Fiscalo API: GET /customers/{id}.

fiscalo_get_document

Get one document with its lines, taxes, totals and status (draft or issued). Fiscalo API: GET /documents/{id}.

fiscalo_get_item

Get one product or service by its Fiscalo id. Fiscalo API: GET /items/{id}.

fiscalo_list_customers

List customers of the company behind the API key. Filter by name, tax number or your own external_id. Fiscalo API: GET /customers.

fiscalo_list_document_series

List the document series of the company. A draft needs an active series (series_id). Fiscalo API: GET /document-series.

fiscalo_list_documents

List documents (invoices, credit notes, quotes and others) with their status. Fiscalo API: GET /documents.

fiscalo_list_items

List products and services in the catalog. Fiscalo API: GET /items.

fiscalo_list_tax_rates

List the global tax-rate catalog (read-only). Use it to find the tax_rate_id for an item or a document line. Fiscalo API: GET /tax-rates.
