In this video, I walk you through the implementation of a complete customer verification flow for a SaaS application using LangGraph by ‪@LangChain‬, MistralAI and persistent storage. Here’s what you’ll learn:

• Overview of the Verification Process: Simulating a help desk
scenario where various details like ID, credit card number, and secret
questions are validated.
• LangGraph and Persistent Storage: How LangGraph persists state using
SQLite, enabling the application to be stateful and resume from
checkpoints.
• Using Mistral AI’s Latest Model: Handling user inputs and gathering data
incrementally for a smooth user experience.
• Conditional Logic in LangGraph: Implementing loops and conditional
branches to collect all necessary information before proceeding.

This video is for anyone looking to understand how to build a customer verification flows using LangGraph, with practical examples and detailed explanations.
