the following steps:Retrieve username to access the ASP’s API: smartBillUserId (Smart Bill Id).
Upload the supplier certificate to enable the ASP in signing invoices.
Generate an authentication/verification Code to allow access to the API methods:
This code will be used as authenticationCode in Sovos, alongside the smartBillUserId and certificatePassword.

Note: The supplier should ONLY generate an Authentication/Verification Code on the ASP’s portal once, and then store it in the Sovos solution for the supplier Company, this allows Sovos to generate a token enabling users to access the API of the Service Provider (ASP) securely.
Note: Authentication/Verification code is only generated once for each Supplier – ASP onboarding relationship. In case the supplier already has an authentication/verification code from previously being registered with the ASP the same code will be used when configuring the supplier Company in the Sovos solution.
