APIs power modern applications, enabling seamless communication between systems, mobile apps, and cloud platforms. But without proper validation, APIs become one of the most exploited attack surfaces. API Security Testing Services help businesses detect vulnerabilities, misconfigurations, and authentication flaws before attackers can exploit them. At QACraft, we deliver API penetration testing services, API vulnerability testing services, and automated API security testing services to ensure your APIs remain secure, compliant, and resilient in today’s evolving threat landscape.
API Security Testing Services are specialized security assessments that validate the confidentiality, integrity, and availability of APIs. Unlike functional API testing, which checks performance and correctness, API security testing services focus on uncovering vulnerabilities like weak authentication, insecure data exposure, improper access control, and injection attacks.
Through API authentication and authorization testing services, we verify OAuth, JWT, OpenID, SSO, and MFA mechanisms to ensure secure access.
We conduct REST API security testing services and SOAP API security testing services to detect flaws in both modern and legacy APIs.

Poorly secured APIs often expose sensitive data like customer records, payment details, or healthcare information. Through API penetration testing services and API vulnerability testing services, businesses can identify weak endpoints, broken authentication mechanisms, and insecure configurations before attackers exploit them.
APIs often connect multiple systems, SaaS platforms, and third-party services. With API authentication and authorization testing services, companies can validate token handling, OAuth, JWT, and session management to ensure only authorized users and applications gain access. This prevents unauthorized data sharing and integration risks.
APIs power mobile apps and cloud environments, making them high-value targets. Our mobile API security testing services secure communication between apps and APIs, while cloud API security testing services safeguard APIs deployed in AWS, Azure, and Google Cloud against misconfigurations, privilege misuse, and insecure endpoints.
Industries like finance, e-commerce, and healthcare must comply with global standards. API vulnerability assessment services help organizations align with PCI DSS, HIPAA, GDPR, and ISO 27001 by validating security measures in APIs. This reduces compliance risks and ensures smooth audits.
At QACraft, we provide comprehensive API security testing services to help organizations identify vulnerabilities and safeguard their digital ecosystems. Our services combine API penetration testing services, vulnerability testing, authentication validation, and automation to deliver complete protection for APIs across web, mobile, and cloud platforms.
At QACraft, we understand that APIs are the backbone of digital ecosystems, but they’re also one of the biggest security risks. That’s why our API Security Testing Services combine API penetration testing, vulnerability testing, authentication and authorization validation, and automated security testing to ensure your APIs are safe, compliant, and resilient.
