API vulnerability testing for REST and GraphQL payment systems is performed by scanning for schema exposure, injection flaws, and access control misconfigurations. Providing the API URL or schema file initiates endpoint enumeration and security validation to identify insecure endpoints.

API fuzzing is an active scanning technique that sends unexpected inputs to REST and GraphQL endpoints to detect authorization flaws and injection vulnerabilities. It validates schema exposure and access control issues by triggering misconfigurations in the target API.

API enumeration detects hidden endpoints, parameters, and methods through passive and active scanning. Security analysts provide an API URL or schema file, and the enumeration process maps the attack surface to identify insecure routes in the target platform.

Yes, jq and ffuf are required dependencies to perform GraphQL and REST API fuzzing. jq processes and parses JSON responses from the API, while ffuf handles the high-speed web fuzzing required to discover endpoints and test injection vulnerabilities.

Assessing payment API misconfigurations and access control issues is best handled through targeted fuzzing and schema validation across REST and GraphQL protocols. This approach identifies insecure endpoints and prioritizes fixes by validating the API against common attack vectors.

Using ffuf for API security testing is limited by its focus on endpoint discovery and basic fuzzing rather than deep business logic validation. It may not detect complex multi-step authorization flaws in payment systems without custom configured payloads and manual verification.
