Capabilities

Tools 13

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.

Discovered
fiscalo_connection_test

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

Discovered

Discovered
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.
