AWS has outlined how to deploy a multimodal WhatsApp ordering assistant designed to handle transactions across several communication formats. The system is built on Amazon Bedrock AgentCore with Amazon Nova 2. Through this architecture, the assistant takes customer orders through text, voice notes, and real-time voice calls on a single business number.
The underlying design maintains a strict structural division, ensuring the channel and ordering layers stay separate. To maintain continuity across interactions, the system relies on one shared memory that recognizes each customer across all three channels. This arrangement allows the assistant to support diverse input types on one number while managing customer recognition through unified memory.
