Great free tools for System Integration : Inspecting the HTTP-based request for API testing 免費好用的API測試工具

In order to setup a  HTTP-based API successfully, it is necessary to check request and response.

Postman is a great tool to check the response, how about the request ?

It can be trouble that if we cannot access a 3rd party system's request log while we have to send request to them . How can we verify the request we made is valid ? If the request will be altered by some middleware we may not able to touch ?

Here is one of the solution , make a mock server to capture the final request to the endpoint.
In past , it may takes time to setup a mock server , now , it becomes super easy. 

The great tool here is beeceptor !!! No registration needed , no installation needed.
Just need one browser tab ~

Steps as simple as below :

1. Create an endpoint at https://beeceptor.com/ and leave this browser tab open.
   The endpoint will be like : 
   https://{your_input_name}.free.beeceptor.com 
   
   
   
   
2. Change the endpoint used in code to the endpoint you just created .
3. Execute the request in code from your IDE or other place , just execute your callout code.
4. Refresh your https://beeceptor.com/ browser tab .
5. Now you can check the request and header you just send, and you may create any response in the mock server .
   
   
   

Is is simple and easy , recommended by many platform like Salesforce.
