Deterministic Agentic Execution in Omnichannel Retail Customer Support
SOC2 Type II
Tool-Calling ReAct Loop
Shopify & Stripe APIs
Bounded Policy Engine
Sub-1.2s Latency
Zero Hallucination
1. Executive Summary & Industry Context
Chatbots traditionally fail because they generate conversational text without the authority or tooling to solve underlying customer problems. This case study details an Agentic AI architecture integrated with Shopify, Stripe, and ShipBob APIs, executing deterministic refund, exchange, and return authorizations within bounded business rules.

Magic Link Re-Authentication
Any action involving address modification or refund destination change requires two-factor email verification.
