Authentication Mode Description

There are five authentication modes for all interfaces provided by the CEC. Table 1 describes the authentication modes.

**Table 1** Authentication modes
Authentication Mode	Description
C1 System Configuration Interface Authentication	The API Fabric AK/SK authentication used by call center configuration interfaces, agent bidirectional call interfaces, and web client access (online chat) interfaces uses the tokenByAkSk interface to obtain tokens.
C2 Monitoring, System Outbound Call, CDR, and Knowledge Base Interface Authentication	The authentication algorithm for the CC-FS (CDR and recording download and others), CC-CMS (system monitoring and statistics collection) and CC-iSales (telemarketing outbound call) uses AK/SK-based request signature authentication.
C3 OIAP Interface Authentication	The authentication algorithm for the OIAP (intelligent chatbot) uses the gettoken interface to obtain tokens.
C4 Agent Operation Interface Authentication	The authentication algorithm for the CC-Gateway (agent voice gateway) uses static or dynamic authentication to obtain GUID information for agent authentication.
C5 Intelligent Auxiliary Interface Authentication	The authentication algorithm for voice recognition result subscription interfaces uses the sign-in authentication interface of the CC-Gateway (agent voice gateway) to obtain GUID information for agent authentication.
C6 OIAP AppCube Interface Authentication	When connecting to the AppCube system, the OIAP obtains the token through the getAppCubeToken Interface.
