In HTTP Request Wizard, I have passed the website name in EndPoint for example “gmail.com” and in Response tab after clicking on Preview its showing the status and raw body, but what next I have to do ?
To give you some information, SOAP and REST API are something to get the information or update or to create new request (posting new data ) to the WEB application in the background instead of doing it in the front end i.e., using UI or HTML pages.
So, if you want to login to a particular application, if you have API available for that WEB application, then you can use them to authenticate and do the required stuff. And as there is API available, you will have clear documentation for those as well with the developers.
Now, make sure you are trying to automate the steps for those web application which is having API. Otherwise, it is not possible to do those
Hope I’m clear and please let me know if you have any doubts
