Web services are web components that allow clients and servers to exchange data. The client SUBMITS a web request to the server, which is subsequently RESPONDED to by the server. The response and the request are linked, and different REQUESTS elicit different responses. A web component or software program that can be accessed through the Internet is known as a web service. Through XML communications ideas, it is mostly used to communicate with web-based applications. For example, if we wish to utilize Google Maps to find a SPECIFIC location, we can use the relevant web service's URL. To do so, we must provide the necessary inputs.

In general, web services are used in conjunction with the protocols listed below:

• HTTP / POST: The HTTP / POST protocol is used to securely send data between clients.
• HTTP / GET: Clients can display sent data partially in the browser's address bar using the HTTP / GET protocol.
• SOAP: SOAP is a protocol for securely transmitting private data.

These channels will be utilised to communicate with customers when exposing web services.
