Online API testing tool: Best practices for developers debugging interfaces

In modern inn development, API (application programming interface) is a bridge between the back and the back. Whether to build RESTful Services, integrated third-party payments, or commissioning of internal micro-services, an efficient, intuitive API Testing tools are essential. Thousands of cells API test tool provides a RETT that does not need to be installed and run by a pure browser Client solution.

Why select an online API test tool?

  • on-call: Open the web page without downloading a huge installation package like Postman or Insomnia.
  • Environment is irrelevant: Whether on Windows, MacOS or Linux or even tablets, a browser can work.
  • Privacy： This tool is based on Fetch API and requests to send directly from your browser (by CORS) (Expressed) without passing any transit server to make sure your Token and API Key are not leaked.
  • Visualization parameter management: Automatically decomposed complex query string to key pairs to avoid errors from manually aggregating URLs.

How do you handle the common cross-domain (CORE) problem?

Because the browser has implemented a "co-source policy" for security reasons, you may encounter a request for a server that is not explicitly allowed to cross the domain `CORS error`。 Solutions include:

  • Development environment: Add `Access-Control-Allow-Origin: * Header ' to the backend code.
  • Debug plugins: The CORS Unblock plugin that installs the browser temporarily bypasses the limit.
  • Agency services: Forward requests using the transit proxy server.

Core Functions Supported by This Tool

1. Full methodological support is requested for: Covers standard GT access data, POST creation resources, PUT/PATCH update resources, and DELETE delete resources.

2. Smart JSON format: Whatever chaos the API returns to JSON, we automatically indent and embellish, and we'll make the embedded structures clear.

3. Local history: Automatically saves your latest 10 requests for quick back and repeat tests, only in your `localStorage '.

4. Response metadata statistics: Displays the HTTP status code, the time frame for the server response and the size of the package, which will help you to perform the underlying performance assessment.

Small technique to enhance API debug efficiency

- Using Params tags: Places the page break parameters (e. g. `page=1&Limit=10`) in the Params list, rather than manually changing URLs.

- Check Headers: Many API requests to set up `Content-Type: application/json ' or `Authorization ' head to ensure that tab is configured correctly.

- Observation status code: 401 Unauthorized, 404 for error of path, 500 Representing a back end collapse. You can judge the problem in a moment by using this tool's high-profile hint.
