agent_payment_check Read-only

Before an AI agent pays, checks the proposed payment against the person's mandate (who allowed it, limits per payment and per period, allowed shops and UPI IDs, end date) and against what the person actually asked for (items, quantities, budget, shop). It works the total out again from the cart lines, and flags lookalike payees, extra items, too much quantity, going over a limit and repeat payments. Returns every check and a receipt signed by Nityaflow. It never pays, holds or moves money: a licensed bank or payment app does that, only after a person approves.

actionobject, required

intentobject, required

historyarray

Earlier payments under this mandate: [{at, total, vpa, status: paid}]. Used for the period limit and repeat check.

create_workflow_draft

Opening the link puts the workflow in the Nityaflow editor with every step filled in; it does not run or send anything until the person tests it and switches it on. Give the person the link and the to-do list. Never put passwords, API keys or tokens in the workflow.

Argument	Type	Description
workflow*	object	The JSON object described by get_workflow_guide: {name, summary, nodes: [{ref, type, name, params}], edges: [{from, out, to}], limits, todo}.

Returns the JSON shape, the rules and every step type with its settings. Then design the workflow and call create_workflow_draft.

gst_credit_match

India GST input tax credit check. Matches the supplier invoices in GSTR-2B against the purchase register from the books (Tally, Zoho Books, Busy, QuickBooks or any list) and sorts every invoice into: matched, amount mismatch, entered twice (duplicate bills), possible match (invoice number or GSTIN written differently), in books but not in GSTR-2B (credit at risk), in GSTR-2B but not in books. A separate checker re-derives the totals, and the result comes with a receipt signed by Nityaflow. Invoices are processed in memory and not stored. It never files or accepts anything on the GST portal.

read-only

Argument	Type	Description
books*	array	Purchase register from the books: a list of invoices like {gstin, invoice, date, name, taxable, igst, cgst, sgst, cess, value}. Use the supplier's bill number, not the voucher number.
client	string	Client or business name, for the receipt.
gstr2b*	any	GSTR-2B: either the JSON file downloaded from the GST portal, or a list of invoices like {gstin, invoice, date, taxable, igst, cgst, sgst, cess}.
period	string	Return period, for example 2026-09.
tolerance	number	Allowed difference in rupees before amounts count as different. Default 1.
