PCI DSS (Payment Card Industry Data Security Standard) is a globally recognized set of security guidelines designed to ensure businesses that accept, process, store, or transmit credit card information maintain a secure environment to protect cardholder data.
Who Needs It
If your business takes payments online, over the phone, or in-store, PCI DSS applies to you. It is mandatory for all merchants, financial institutions, and service providers handling card data, regardless of the company’s size or transaction volume.
The 12 Core Requirements
The standard consists of 12 fundamental requirements organized into 6 main control objectives:
Why Compliance Matters
Achieving compliance—often demonstrated through a Self-Assessment Questionnaire (SAQ) or a Report on Compliance (RoC)—protects your customers and your business from data breaches. Non-compliance can result in devastating penalties, forensic investigation costs, loss of merchant processing privileges, and heavy brand damage.
For more specific details, requirements, and self-assessment tools tailored to your business, refer to the official PCI Security Standards Council website.
An API (Application Programming Interface) is a set of rules that lets different software programs communicate and share data with each other. Think of it like a waiter in a restaurant: you (the application) place an order (a request), and the waiter takes it to the kitchen (the server) and brings back exactly what you asked for.
How They Work
For business analysts (BAs), APIs are crucial business enablers that connect systems, automate workflows, and drive revenue. Categorizing APIs helps BAs identify technical impacts, scope integration requirements, and align solutions with strategic business goals.
Categorization can be divided into three primary frameworks: Access Level, Business Purpose, and Architecture Style.
1. By Access Level (Audience)
This categorization defines who has permission to use the API and dictates security requirements.
2. By Business Purpose (API-led Connectivity)
This approach, often used in integration methodologies like MuleSoft, categorizes APIs by their role in the enterprise architecture.
3. By Architecture Style (Technical Format)
While solution architects define the exact protocol, BAs must understand these styles to document data flow, map payloads, and communicate limitations with developers.
Key API Concepts for BAs
Business analysts rarely build APIs, but they must understand high-level concepts to document API requirements effectively:
GET (Read), POST (Create), PUT/PATCH (Update), and DELETE (Remove).
