10 Best REST API Developer Tools for Increasing Productivity | Connect Infosoft

It is not enough to create an application; you must also test it to see if it meets - or even surpasses - expectations. API testing determines whether a programme meets typical performance, functionality, and security criteria. In this article, we'll look at some of the greatest REST API tools for increasing productivity.

What is a REST API?

A REST API (Representational State Transfer Application Programming Interface) is a widely used architectural style for designing networked applications. It is based on the principles of the REST architectural pattern, which emphasizes simplicity, scalability, and statelessness.

REST APIs enable communication between different software systems over the internet by using standard HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources. These resources can be data entities, such as users, products, or articles, which are accessed and manipulated through the API.

Best REST API Tools:

Here are 10 popular Best REST API developer tools that can help increase productivity:

1. Postman:Postman is a popular tool for API development and testing. It enables developers to efficiently design, construct and test APIs. Postman is an easy-to-use interface for making requests, maintaining environments and automating operations.

Some of the features of Postman are:

• The interface enables the extraction of data from web APIs.
• Ability to write Boolean tests
• Comprises built-in tools, collections, and workspaces
• Not a command-line based tool which makes it easy to paste text into a command-line window.

2. Swagger (OpenAPI):Swagger, now known as OpenAPI, is a specification and set of tools for designing, building and documenting RESTful APIs. It provides a standardized way to describe APIs, generate client SDKs and generate interactive API documentation.

Below are some of its major features:

• API design, development, documentation and security testing are all supported.
• Several open-source tools for OpenAPI Specification (OAS) are provided.
• Supports API mocking and virtualizations
• Provides API governance and monitoring.

3. Insomnia:Insomnia is an open-source API testing tool that offers a comprehensive environment for designing, debugging and testing REST APIs. It supports authentication, scripting, and collaboration features to streamline the API development process.

Some of the features of Insomnia are:

• Workspace Organization: Manage API projects in separate workspaces.
• Request Building: Easily create HTTP requests with details like headers and parameters.
• Request Collections: Group related requests into collections.
• Environments: Define variables for different scenarios like dev, test, and prod.

4. Paw:Paw is a macOS-specific API development tool that offers a visual interface for creating and testing RESTful APIs. It allows you to define complex request flows, handle authentication and generate code snippets for various programming languages.

Some of the features of Paw are:

• Dynamic Values: Easily manage variables and data.
• Request Building: Create complex API requests.
• Code Generation: Generate code snippets for integration.
• Environment Variables: Set variables for different scenarios.

5. Apigee:Apigee is an API management platform with tools for designing, implementing, securing, and analysing APIs. It offers features like API lifecycle management, security policies, analytics, and developer portal capabilities.

Some of its features are:

• API Design: Create APIs visually.
• Security: Robust authentication and access control.
• Analytics: Real-time usage and performance insights.
• Traffic Control: Set limits and scaling for traffic.
• Developer Portal: Interactive documentation and testing.

6. RestAssured:RestAssured is a Java-based testing framework for REST APIs. It provides a simple and intuitive syntax for writing API tests, handling authentication, and validating responses. RestAssured works well with well-known testing frameworks such as JUnit and TestNG.

Its key features are:

• Simplified Requests: Easily create HTTP requests with concise syntax.
• Response Validation: Validate API responses using built-in assertions.
• Request Specifications: Set headers, parameters, and authentication in a readable manner.
• Automated Testing: Integrate with testing frameworks for automated testing.
• Data-Driven Testing: Test scenarios with dynamic data using data providers.

7. WireMock:WireMock is a flexible and easy-to-use HTTP mocking tool. It allows developers to simulate API responses and behaviors, making it useful for testing and development in API-dependent projects.

Its key features are:

• Request Matching: Set criteria for request matches.
• Response Generation: Craft detailed responses.
• Dynamic Responses: Use JavaScript or JSON for dynamic behavior.
• Response Templating: Modify responses based on requests.

8. Charles Proxy:Charles Proxy is a web debugging proxy tool that enables capturing and inspecting HTTP/HTTPS traffic. It helps analyze API requests and responses, debug issues, and simulate different network conditions.

Its key features are:

• Traffic Monitoring: Analyze HTTP/HTTPS traffic.
• Request/Response Inspection: View details and headers.
• SSL Proxying: Decrypt and inspect encrypted traffic.
• Bandwidth Throttling: Simulate network speeds.

9. Dredd:Dredd is an open-source command-line tool for testing API documentation against implementation. It validates whether the API implementation matches the API blueprint or OpenAPI specification, ensuring consistency and accuracy in API development.

Its key features are:

• API Blueprint and OpenAPI Support: Test APIs documented in these formats.
• Automated Contract Testing: Verify API behavior against documentation.
• Live Documentation Verification: Identify discrepancies in real-time.
• CI Integration: Easily integrate into CI pipelines.

10. Fiddler:Fiddler is a web debugging proxy tool that allows capturing, analyzing, and modifying HTTP/HTTPS traffic. It helps debug and monitor API requests and responses, inspect headers, and simulate different network scenarios.

Its key features are:

• Traffic Monitoring: Capture HTTP/HTTPS traffic.
• Request/Response Inspection: Examine details, headers, and timings.
• Web Session Manipulation: Modify requests and responses.
• SSL/TLS Decryption: Inspect encrypted traffic.

Conclusion:

These tools offer various features and functionalities, so it's important to choose the one that best fits your specific needs and preferences.
