Automated API Definition (AAD) tool is installed as part of the setup. ABS discovers the APIs when the discovery is enabled. The automated setup sets up the discovery mode. APIs are discovered by ABS when a global API is defined in PingIntelligence ASE. AAD fetches the discovered APIs from ABS and adds them in ASE. API model training starts after the APIs are added in ASE. For more information, See API discovery and configuration.
