title: Ualá Bis API Cobros Online v2 Orders API
description: Ualá Bis online payments (checkout) API for Argentina. Creating an order returns a unique hosted checkout link where the buyer selects a payment method (credit card, debit card, and QR coming soon). Orders can be retrieved individually, listed with filters and cursor pagination, and refunded within 90 days. Status changes are pushed to a merchant-supplied notification_url via webhooks. Generated by API Evangelist from the published documentation at developers.ualabis.com.ar — the provider does not publish a machine-readable spec.
