How should Stripe build privacy and abuse controls into Issuing

Problem Statement Description

Product context: Stripe is financial infrastructure for internet businesses; its products include payments, Checkout, Billing, Connect, Radar, Issuing, Terminal, and tax tools.

Stripe Issuing lets platform businesses create, manage, and programmatically control payment cards for their own users, contractors, employees, or customers. In this interview, you are asked to think like a Technical PM responsible for building privacy and abuse controls into Issuing without breaking the speed, flexibility, and developer experience that platforms expect from Stripe.

The problem sits at the intersection of cardholder data privacy, transaction authorization, fraud prevention, platform risk, compliance, and API design. A platform may need to issue cards at scale, set controls, monitor usage, and respond to suspicious behavior, while Stripe must protect sensitive personal and financial data, prevent misuse of issued cards, support regulatory obligations, and maintain high reliability for legitimate transactions.

Your scope should include both product requirements and technical system considerations. Think about what controls should exist, who configures them, what data is exposed or hidden, how abuse is detected and acted upon, how developers integrate these capabilities, and how Stripe balances customer control with platform-level safety.

The experience should consider:

- The primary users and stakeholders, including platform developers, risk teams, compliance teams, cardholders, and Stripe internal operations.

- Privacy requirements around cardholder identity, card details, transaction data, authorization metadata, logs, webhooks, dashboards, and API access.

- Abuse scenarios such as stolen credentials, synthetic identities, mule accounts, unauthorized card creation, suspicious spending, merchant category misuse, and coordinated fraud.

- Technical requirements for APIs, permissions, role-based access, audit logs, data minimization, encryption, tokenization, and secure webhook delivery.

- Real-time decisioning needs for authorization controls, spending limits, merchant restrictions, velocity checks, and risk interventions.

- Reliability and latency trade-offs, especially when controls are evaluated during transaction authorization.

- Compliance, regional data handling, retention policies, dispute workflows, and obligations across different markets.

- Rollout, observability, customer migration, incident response, false-positive handling, and developer-facing documentation.

The goal is to define a thoughtful technical product approach for privacy and abuse controls in Stripe Issuing: clear enough for engineering to build, safe enough for a regulated financial product, usable enough for platform customers, and flexible enough to support different business models without exposing Stripe, platforms, or cardholders to unnecessary risk.
