To make an electronic signature we need a digital certificate and an electronic signature application. For this, Uanataca has created the One-Shot Signature service for the signing of transactions, which in a single step and through a single API, generate a single-use digital certificate which electronically signs with said certificate all the PDF documents that have sent in the transaction.

To ensure the security of the signature, as with the secret codes we receive by SMS when we do internet banking, digital certificates are only valid for use in a single transaction. By integrating the One-Shot Signature API into your application you can have your customers, employees, suppliers or partners sign electronically without losing the current user experience and with the maximum guarantees of the qualified electronic signature.
