create_invoiceGenerate a GST e-invoice and get an IRN (Invoice Reference Number) from the IRP (Invoice Registration Portal, run by GSTN), stamped through the Sandbox.co.in GSP. Bring your own Sandbox credentials via headers x-sandbox-api-key AND x-sandbox-api-secret (sign up at sandbox.co.in). Your GSTIN must already have GST e-Invoice API access enabled on the e-Invoice portal and mapped to Sandbox as your GSP. e-Invoicing is B2B only — BOTH seller and buyer must have valid 15-char GSTINs. Give flat fields (seller/buyer GSTIN + name + address, doc_number, line items with hsn_code, price, quantity, gst_rate) and this server COMPUTES the INV-01 tax schema for you: taxable value per line, CGST+SGST split for same-state supply vs IGST for cross-state supply (decided automatically from the seller GSTIN state vs the place-of-supply state), item totals, and the invoice totals (AssVal / TotInvVal). Returns Irn, AckNo, AckDt and SignedQRCode.
query_invoiceLook up a GST e-invoice by its IRN at the IRP. Status values: ACT (active / valid) or CNL (cancelled). Safe to call anytime.
cancel_invoiceCancel a GST e-invoice at the IRP. IMPORTANT: the IRP only allows cancellation WITHIN 24 HOURS of IRN generation (and only if no e-way bill is active / it was not already cancelled) — after 24h you must instead issue a credit note. A reason code is required: 1 Duplicate, 2 Data entry mistake, 3 Order cancelled, 4 Others (default 4). Remarks are required by the IRP.
