Optional Device Certificate
SIGN ES API uses device certificates for signature and sending of TicketBAI XML files. This device certificates are provided by Izenpe, a trust service provider for electronic signature services promoted by the Basque Government and the Provincial Councils.
This is an optional procedure for those integrators who wish to use their own device certificates in the SIGN ES API. If this is not your case, please refer to the Device Certificate section to understand how fiskaly’s managed device certificate makes the integration easier for you.
Device certificate creation: Step by step
