API Business Logic Abuse Testing

Automated scanners still miss business logic. An API can pass every scan and still let one user act as another, skip a payment step, or drain a rate limit that was never actually enforced.

BOLA & IDOR Testing

Object-level access control

Manually tests every endpoint for broken object-level authorization, the API flaw class scanners are structurally unable to catch.

Workflow Bypass

Sequence & state abuse

Attempts to skip, reorder, or replay steps in a multi-step workflow — checkout, approval, onboarding — to reach an unintended end state.

Rate-Limit & Quota Abuse

Resource-exhaustion testing

Tests whether rate limits and quotas hold under realistic abuse, including across accounts and API keys, not just a single client.

Machine-Client Abuse

Agent & automation-consumer testing

Tests how the API behaves when called by automated agents and scripts instead of a browser, where business logic assumptions break first.
