AfipGetLastVoucher

Description

Queries Argentina’s AFIP for the last authorized voucher number for a specific point of sale and voucher type. Returns both the last number (last_voucher) and the next one to use (next_voucher = last_voucher + 1).

This node is useful as a step before AfipCreateInvoice when you need to know the next number before building the full invoice payload.

Configuration

credentials_id	credentials	Yes	AFIP SDK server credential
voucher_type	select	No	Type: 1=Invoice A, 6=Invoice B, 11=Invoice C (default: 6)
point_of_sale	number	Yes	Point of sale number registered in AFIP

  "next_voucher": 42,
  "voucher_type": 6,

}

Notes

• If no voucher of that type has ever been issued at that point of sale, returns last_voucher: 0 and next_voucher: 1
• voucher_type and point_of_sale can also come from the data object if not set in the node config
