The Know Your Customer (KYC) process is a critical part of financial services and plays a key role in fraud prevention. Before a customer can access many financial products, organisations must verify their identity and assess potential risk.

In this video, we explore how to implement a durable KYC process using Temporal. Rather than focusing solely on the business workflow, we'll examine how Temporal helps build resilient, long-running systems that can survive failures and continue operating reliably.

Topics covered include:

- Modelling the KYC process as a Temporal workflow
- Long-running workflows and human-in-the-loop approvals
- Durable timers for SLA monitoring and escalation
- Retry policies for recovering from transient database failures
- Workflow replay and recovery when a worker process crashes
- Building fault-tolerant business processes that remain reliable over time

Whether you're new to Temporal or looking to understand how durability applies to real-world business processes, this video provides a practical, end-to-end example.

A walkthrough of building a durable KYC (Know Your Customer) workflow using Temporal in .NET. Covers the full KYC process including automatic approval/rejection, human-in-the-loop compliance review with 72-hour SLA timers, and escalation flows. Demonstrates Temporal's resilience by intentionally failing a database and a worker process, showing how Temporal maintains workflow state and retries activities automatically. Includes a code walkthrough of workflows, activities, retry policies, signals, queries, and the worker process in C#.
