APIs power modern applications, but they also introduce critical security risks when left improperly tested. This guide explains a step-by-step API VAPT framework for enterprise security teams, covering authentication testing, BOLA vulnerabilities, rate limiting, business logic flaws, fuzzing, injection testing, CI/CD integration, and continuous security validation. The article aligns with OWASP and NIST standards while demonstrating how organizations can combine automated scanning with manual penetration testing to secure REST and GraphQL APIs at scale. It also includes insights into enterprise API security operations, remediation workflows, and downloadable API VAPT resources from Infosprint Technologies.
