Apartment testing mostly relies on authentication since it guarantees just approved users access to private resources. Restful APIs run modern apps, therefore reliable authentication methods become rather crucial to prevent illegal access and data leakage. This paper examines several authentication methods in API testing under mostly used methods including OAuth and JSON Web Tokens (JWT). It shows how these systems limit access, confirm user identity, and provide security preservation. Furthermore addressed are API automation and authentication testing using the well-known Java-based REST Assured tool. A case study is given showing how various authentication techniques could be actually used in API testing. By means of a real-world scenario, we demonstrate how to set authentication, verify token-based access, and guarantee the resilience of API security. Important courses cover frequent mistakes to prevent, effective ways to implement authentication in API testing, and tools for testers and developers to enhance the security of their API testing activities. We also discuss authentication testing and the well-known Java-based API automation testing program REST Assured. Rest Assured simplifies the evaluation of authentication systems by helping testers control tokens, set headers, and rapidly evaluate answers. Regarding token expiration, session hijacking, and erroneous authorization, good authentication management helps to reduce risks in API testing. A case study showing the actual deployment of multiple authentication techniques in API testing is offered to offer pragmatic insight. The case study covers how testers could assess authentication systems, how authentication is applied in an API, and how possible security problems could be found and fixed. This practical example will enable readers to completely grasp appropriate ways for maintaining API authentication. Common pitfalls to avoid, best practices to apply authentication in API testing, and realistic recommendations for testers and developers to raise the security of their API testing processes are among the important insights in this post. By the end of this paper, readers will be totally aware of how to properly check authentication systems, therefore guaranteeing strong and safe API implementations
