OPTIMIZING MICROSERVICES INTERACTION VIA API: STRATEGIES FOR DOCUMENTATION AND MONITORING USING POSTMAN AND SWAGGER

Kuzmin Nikolay Nikitovich, Zavjalov Anton Vladimirovich

The article examines the problem of optimizing the interaction of microservices via APIs, which is a relevant direction in the development of distributed systems. The introduction substantiates the need to increase the efficiency of data exchange between system components, highlighting the importance of API documentation and monitoring to ensure flexibility, scalability, and reliability. In particular, attention is paid to strategies for using Postman and Swagger tools, which contribute to standardizing and automating the testing and documentation processes. The methodological section of the study describes an approach based on a comprehensive analysis of existing practices for integrating microservices, as well as the application of experimental scenarios using Postman for conducting functional tests and monitoring API performance. The Swagger tool is used to generate interactive documentation, which simplifies API reading and maintenance. A detailed description is provided on the development of test sets and data visualization methods, ensuring an objective comparison of the effectiveness of various optimization strategies. As a result of the experiment, the advantages of integrating Postman and Swagger tools for improving the quality of microservices interaction were identified. The experimental section demonstrates that the application of a flexible testing system combined with automated documentation reduces the time spent debugging interfaces and minimizes the likelihood of data exchange errors. The results show an improvement in key performance indicators, a reduction in response time to failures, and increased transparency of the development processes. The discussion of the research results emphasizes the possibility of using a combined approach to enhance the level of interaction between individual services in the rapidly changing architecture of applications. The article underlines that optimization through efficient documentation and constant monitoring is capable of ensuring the resilience and reliability of modern distributed systems, as well as stimulating the development of new tools for automating integration processes. Thus, the proposed strategies can serve as a basis for further research in the field of perfecting the architecture of corporate applications and increasing the flexibility of their integration interactions.
