# Overview

Our platform provides you with a variety of powerful tools to thoroughly test your [**Application Programming Interface( API)**](/api-testing/getting-started/intro-to-api.md). With **API Testing Service**, you can easily perform Functional Testing, Performance Testing and API Process Testing (also known as API chaining) across REST, SOAP, and GraphQL APIs.

* **Functional Testing:** To verify the functionality and accuracy of the API, ensuring it performs as intended by performing assertions on desired responses. For comprehensive guidance on using this feature, refer to the complete documentation on [**Functional Testing**](/api-testing/functional-testing/functional-testing.md).
* **Performance Testing:** Testing involves gradually intensifying the workload to observe the API's performance under heavier demand. Within this process, you can track response durations, review the status codes and advanced results associated with each request. For comprehensive guidance on using this feature, refer to the complete documentation on [**Performance Testing**](/api-testing/api-process-testing/performance-testing/performance-testing.md).
* **API Process Testing:** Process Testing entails linking a series of APIs, where the output of one API serves as input for the next API. By running them sequentially and examining the collective outcomes, you can understand the entire workflow. For comprehensive guidance on using this feature, refer to the complete documentation on [**API Process Testing**](/api-testing/api-process-testing/api-process.md).
* **Project Set Up:** The setup process within the API Testing Service introduced several functionalities, including Certificates, Global Variables, Environment Variables, Prerequisite APIs, Dynamic Variables, as well as Integration and Database Assertion capabilities. For comprehensive guidance on using these features, refer to the complete documentation on [**Project Set Up**](/api-testing/project-setup/project-set-up.md).
