- Its sample POST sends JSON with an issuer RUC and returns an approval state, CDC, and KuDE PDF link.
Field notes
The illustrated request supplies an invoice type, customer RUC, item, price, and IVA value; the example response includes an approval state and a CDC. The page compares a shared pool for 20 clients with two per-company pricing examples, and lists language-specific integration examples from PHP through Delphi. Sandbox access is offered at no cost, but the page says users must request a test key and documentation.
