get_document_rules
Get fields and tax rules for a document
Returns what to collect before creating a document of a given type and country: required, recommended and optional fields, the tax ID and tax names, the country's invoicing rules (for example India GST rule 46, UK VAT invoice contents), the CGST/SGST versus IGST split and state codes for India, and credit-note reasons. Read-only.
Parameterscountryrequireddocument_typerequired
create_document_link
Create a prefilled document link
Validates a document (invoice, quote, proforma invoice, receipt or credit note) and returns editor_url, a short link that opens it prefilled in the LuckPanda editor, where the person can review, edit and download the PDF. Also returns the totals with tax worked out, the required fields still missing and any parts left out as invalid. Side effect: the document is stored on LuckPanda's servers for 7 days under a random link id (not listed or indexed), and every call creates a new link. Nothing is issued, numbered or sent. Use details the person gave; do not invent them.
Parametersdocrequiredpage
create_document_pdf
Create a document PDF
Generates a PDF of a document (invoice, quote, proforma invoice, receipt or credit note) and returns it base64-encoded in structuredContent.pdf_base64, with its verification URL and an editor_url that opens the same document in the editor. PDFs from this tool include a LuckPanda footer and a verification QR code. Side effects: stores a verification record for the PDF (issuer name, document type, date, currency and total; no client details) and a 7-day copy of the document behind editor_url. Limit: about 40 PDFs an hour per network.
