How To Prepare User Manual For Api Service
What is a REST API?
An API or Application Programming Interface is a set of programming instructions for accessing a web-based software application.
In other words, a set of commands used by an individual program to communicate with one another directly and use each other's functions to get information.
Rest stands for Representational State Transfer. It is an architectural style and an approach for communication used in the development of Web Services. REST has become a logical choice for building APIs. It enables users to connect and interact with cloud services efficiently.
For example, a Google website can have API for various functions like search, translations, calendars, etc.
In general API's are like below, they have server name, paths.., etc
There are mainly 4 methods involve in API Testing like GET, POST, Delete, and PUT.
- GET- The GET method is used to extract information from the given server using a given URI. While using GET request, it should only extract data and should have no other effect on the data.
- POST- A POST request is used to create a new entity. It can also be used to send data to the server, for example, customer information, file upload, etc. using HTML forms.
- PUT- Create a new entity or update an existing one.
- To implement the API, you have to add the Doubleclick.jar file to your class path. The call is local. A web service is a form of API where the interface is defined by means of a WSDL. This allows remote calling of an interface over HTTP. If Doubleclick implemented their interface as a web service.

- DELETE- Removes all current representations of the target resource given by a URI.

API testing requires an application to interact with API. To test an API, you require two things,
- Testing Tool/Framework to drive the API
- Writing down your own code to test the API
Rest API can be tested with tools like:
- Advanced Rest Client
- Postman-Rest Client
- Curl in Linux
Here we will be using Advanced Rest Client, below are the steps to get Advance Rest Client,
How to get Advanced Rest Client
- Go to Google Chrome's Web Store
- Search for 'Advanced Rest Client' or directly go here and Install the extension
- Select the 'Advanced Rest Client' icon under chrome's app section - chrome://apps/
Once the installation is done, follow the below test for Testing RESTful API
Steps for Testing REST API
Here we are using rest client extension in chrome browser. To understand in a clear way, we are using dummy API '
Step 1): Launch the app Advanced REST client (ARC), once it is installed successfully.
Step 2): Enter the URL of the API in the URL textbox.
Step 3): Select the method for the type of HTTP method to hit- e.g. POST
Step 4): Provide Headers Set, in the Headers textbox. Click on Insert header set.
Step 5): Next Click on USE THIS SET.
Step 6):
- Now switch to Body Tab.
- Set the required Body content type and Editor view e.g. Body content type : application/json
- Editor view : Raw input.
- Under Payload, pass the request body of the API in the form of key-value pairs e.g. {{'key1':'value1','key2':'value2'}. If it is post API, then we need to pass body or parameters. We will pass under given payload.

- Hit the send button.
- You can click on DETAILS button to see the Response headers.
Here are the response details:

User Manual Template
Mainly, for Web API Testing, we need to check response code, a response message, and response body.
Below are the various response code, one might encounter while API Testing.
REST API Test Tool
Challenges for API Testing
The interesting problems for testers are:
- To make sure that the test harness varies the parameters of the API calls in such a way that it verifies the functionality as well as expose the failures. It includes exploring boundary condition and assigning common parameters
- Creating interesting parameter value combinations for calls with two or more parameters
- Identifying the content under which the API calls have to be made. Which might include setting external environment conditions ( peripheral devices, files, etc.) as well as internally stored data that affects the API
- Sequencing API calls as per the order in which the function will be executed
- To make the API produce useful results from successive calls.
