Basics of API
If you are new to API, Lets review the basics terminology used in API .
API stands for Application Programming Interface. APIs act as a software intermediary to enable two software components to communicate with each other.
End point: Address where API is hosted on the Server.
HTTP methods: which are commonly used to communicate with Rest API’s are GET, POST, PUT, and DELETE
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. No Payload/Body required,To send input data in GET use Query Parameters
POST- A POST request is used to send data to the server, for example, customer information, file upload, etc. using HTML forms.To send input data in POST use Body Payload
PUT- Replaces all current representations of the target resource with the uploaded content.
DELETE- Removes all current representations of the target resource given by a URI.
Resources represent API/Collection which can be accessed from the Server
Path Parameters:Path parameters are variable parts of a URL path. They are typically used to point to a specific resource within a collection, such as a user identified by ID
Query Parameters:Query Parameter is used to sort/filter the resources.Query Parameters are identified with "?"
Headers/Cookies:Headers represent the meta-data associated with the API request and response. In general terms, we were sending Additional details to API to process our request.
Example : Authorization details.
By using above information we can construct the End Point Request URL as below
