API Penetration Testing Services
APIs connect customer applications, mobile platforms, partners, cloud services and internal systems. Detox Technologies provides expert-led API penetration testing services for REST, GraphQL and SOAP APIs, identifying authorization flaws, authentication weaknesses, business logic abuse and sensitive data exposure that automated scanners often miss.
API Security Testing Beyond Automated Scans
Our API security assessments combine careful automation with manual testing by experienced security professionals. We validate how an attacker could misuse API functions, cross account or tenant boundaries, manipulate workflows, access restricted records or disrupt critical services. Every confirmed issue includes evidence, business impact and practical remediation guidance.
Testing can cover mobile and web back-end APIs, partner integrations, microservices, cloud-hosted endpoints, API gateways and identity integrations.
What Our API Penetration Testing Covers
Authentication and Token Security
We assess login flows, API keys, bearer tokens, JSON Web Tokens, refresh tokens and session handling. Testing looks for weak validation, token replay, signature or claim-handling mistakes, missing expiration controls and authentication bypass paths.
Authorization and Object-Level Access
Testers determine whether users can access or modify records belonging to another customer, role, business unit or tenant by changing identifiers or request parameters. Function-level authorization checks identify privileged operations exposed to lower-trust users.
Business Logic Abuse
We examine account creation, password recovery, approvals, purchases, refunds, invitations, file processing and administrative workflows. This reveals limit bypasses, workflow manipulation, duplicate execution and other abuse cases that signature-based scanners cannot understand.
Injection and Input Validation
Testing covers injection paths involving databases, commands, templates, XML processors, server-side requests and downstream services. We inspect data types, nested objects, file uploads, content types and unexpected values across REST, GraphQL and SOAP interfaces.
Data Exposure and API Resilience
We inspect response bodies, errors, metadata and undocumented fields for excessive data exposure. Rate-limit and resource-consumption testing assesses whether sensitive or expensive operations can be automated at scale, including GraphQL depth, batching and resolver abuse.
Reporting, Remediation and Retesting
Deliverables include an executive summary, confirmed findings, severity, affected endpoints, evidence and actionable remediation. After fixes are deployed, Detox can retest the API and confirm whether security weaknesses have been resolved effectively.
Combine API testing with web application VAPT, mobile application security testing, cloud penetration testing or broader penetration testing services.
FAQS
Frequently Asked Questions
API penetration testing is an authorized security assessment that identifies and safely validates exploitable weaknesses in REST, GraphQL, SOAP or other application interfaces. It covers technical vulnerabilities as well as authorization and business logic risks.
Yes. REST testing focuses on endpoints, methods, identifiers, authorization and data handling. GraphQL testing additionally examines schema exposure, resolvers, mutations, subscriptions, aliases, batching and query-complexity abuse.
The scope may include API documentation or an OpenAPI specification, test accounts for relevant roles, endpoint details and agreed testing restrictions. Black-box assessments are also possible, but documentation and multiple roles usually improve business-logic coverage.
Testing is recommended before major releases, after authentication or architecture changes, before important partner integrations, during compliance preparation and periodically for APIs that process sensitive or business-critical data.
