The AVOXI Core Billing API was discontinued as of December 17, 2020.
The Billing API was previously used to provide access to system usage records needed for generating customer invoices. The information could then be integrated into billing systems for accounting purposes and support metadata querying for calls that customers have placed within the AVOXI Core environment.
Based on market and customer demand, we will be working on various APIs within our new AVOXI Genius platform.
