SOAP is like a universal translator that helps them understand each other. Now, when these programs talk, they use a special type of text called XML. It's like a format that's easy for both programs to read, like having a conversation in a language that both friends understand. So, SOAP is kind of like a language translator for computers, and XML is the language they use to communicate. This way, even if two programs are running on completely different systems, they can still understand each other and share information. SOAP Request A SOAP request consists of a SOAP envelope that contains the SOAP header and the SOAP body. Here's a basic example of what a simple XML request in SOAP might look. <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope     xmlns:soapenv="http://schemas...

Next.js , an advanced React framework, streamlines web application development with features like server-side rendering and automatic code splitting. Creating APIs in Next.js is advantageous due to its built-in API routes feature, offering a seamless and integrated approach for handling server-side logic or connecting to databases. This simplifies the development process, ensuring efficient communication between the frontend and backend within the same framework. Route Handlers allow you to create custom APIs. Note: Route Handlers are only available inside the app directory.  Route Handlers are defined in a route.js|ts file inside the app directory. app/api/route.ts export const dynamic = 'force-dynamic' // defaults to auto export async function GET(request: Request) {} Supported HTTP Methods are: GET, POST, PUT, PATCH, DELETE, HEAD, and OPTIONS . Example: export async function GET() {   const res = await fetch('https://data.mongodb-api.com/...', {     ...
