Web GUI based API Executor Application like PostMan -- 3

Want to create a Web based GUI on which one can post request ( receive response also on +ve/-ve), do get call, do patch call, do delete call, do purge, head, options, do put call in a web based GUI application.

The URL should be dynamic and can be coming from different servers ( read from backend server like, consul or yaml files), and as postman once we send suppose a URL to fetch the password, it can generate the response and save to other calls to do the REST/SOAP calls.


Code Language : java, springboot, Microservices(for different API services), URL change implementation for picking either with server & manual if not found, also, have structure to update the certificates in case some server requires certificate to access the password token.

Also. after closing the APP, when again restarted, previous work should not get lost.

Login Token Should generate a password should be saved automatically to the contents of the POST request to send JSON/XML requests.

URL will act as variable for LOCAL, IFT, SIT, PREPROD, SVT, PROD, OTHERS which are editable for domain name where I can put the url domain Name manually in GUI.
