#  API Hacking Essentials (Auth, Tokens, BOLA/BFLA, Rate Limits, Testing Workflow)

> Build practical API security testing capability, from authentication and token handling to authorisation flaws, rate limiting, and evidence-based reporting.

## Overview

API Hacking Essentials is a hands-on programme designed to help learners test modern APIs safely and systematically. You will learn how API security fails in practice, how attackers exploit weak authentication and authorisation, and how to validate issues responsibly within clear scope boundaries.

Delivered through mentor-led sessions, the course uses practical scenarios that mirror real API testing engagements. You will map endpoints, understand identity and token flows, detect weak access controls such as BOLA and BFLA patterns, and test rate limits and abuse controls using a method-led approach rather than guesswork.

Across two intensive days, you will build a repeatable API testing workflow and produce an evidence-based mini report pack with developer-ready remediation guidance. Aligned with recognised best practices including ISO, GDPR, NIST and SOC 2, ensuring skills remain practical and deployable in real organisations. All prices are exclusive of VAT (where applicable). Group enrolments and custom packages available.

## Prerequisites

- Basic understanding of web concepts
- Familiarity with HTTP requests (helpful)
- Understanding of core security principles

## What you will learn

- Design a structured API security testing workflow.
- Analyse endpoints to map data flows and trust boundaries.
- Implement safe validation for auth and token weaknesses.
- Lead authorisation testing for BOLA and BFLA patterns.
- Communicate findings with clear remediation guidance.
- Evaluate abuse controls including rate limiting and enumeration risk.

## Skills you will gain

- API testing workflow design
- Endpoint mapping and prioritisation
- Token lifecycle and common flaws
- Authentication model understanding
- BOLA and BFLA testing patterns
- Rate limiting and abuse checks
- Evidence capture for developers
- Remediation-focused reporting

## Curriculum

1. **Module 1: Getting Ready**
   - Scope, safety, and responsible testing behaviour
   - Evidence standards, note-taking templates, and lab setup
   - API basics: endpoints, methods, parameters, status codes
2. **Module 2: API Testing Workflow and Attack Surface Mapping**
   - Discovering endpoints and mapping request patterns
   - Understanding data flows and trust boundaries
   - Building a test plan and prioritising high-risk areas
   - Practical scenarios: turning user stories into test cases
3. **Module 3: Authentication and Token Handling**
   - Common auth models: sessions, API keys, OAuth concepts
   - Tokens: structure, lifecycle, and common mistakes
   - Handling refresh logic and logout assumptions
   - Practical labs: identifying weak auth behaviours safely
4. **Module 4: : Authorisation Flaws (BOLA/BFLA)**
   - Object-level access control failures (BOLA) patterns
   - Function-level authorisation failures (BFLA) patterns
   - Role testing: permissions, routes, and hidden functions
   - Practical labs: proving access control issues with evidence
5. **Module 5: Rate Limits, Abuse Controls, and Business Logic**
   - Rate limiting and throttling expectations
   - Enumeration and brute-force resistance checks
   - Pagination, filtering, and mass assignment patterns
   - Practical scenarios: abuse case testing and safe validation
6. **Module 6: Reporting and Developer-Ready Fix Guidance**
   - Writing findings: impact, evidence, reproduction steps
   - Remediation guidance and verification steps
   - Severity reasoning and prioritisation
   - Mini report pack: peer review and quality check

## Frequently asked questions

**Is this course suitable if I am new to API security?**

Yes, if you understand basic web concepts. The programme starts with workflow and API fundamentals before moving into auth, tokens, and authorisation flaws.

**Does this course need an exam?**

No. There is no external exam. You receive an Xcademia certificate of completion based on practical participation and deliverables.

**Will we test real production APIs?**

No. All practical work is carried out in safe lab environments and controlled scenarios with clear scope boundaries.

**What will I produce during the course?**

You will produce endpoint maps, evidence captures, and a mini report pack with developer-ready findings and remediation guidance.

**What tools will we use?**

You will use common, safe API testing tools and structured methods. The programme focuses on workflow and evidence, not tool dependence.
