This template guides you through CRUD operations (GET, POST, PUT, DELETE), variables, and tests.

\n

🔖 How to use this template

\n

Step 1: Send requests

\n

RESTful APIs allow you to perform CRUD operations using the POST, GET, PUT, and DELETE HTTP methods.

\n

This collection contains each of these request types. Open each request and click \"Send\" to see what happens.

\n

Step 2: View responses

\n

Observe the response tab for status code (200 OK), response time, and size.

\n

Step 3: Send new Body data

\n

Update or add new data in \"Body\" in the POST request. Typically, Body data is also used in PUT request.

\n
{\n    \"name\": \"Add your name in the body\",\n    \"age\": number value range from -2^15 to 2^15,\n    \"department\": \"enter your B.tech or Masters stream\"\n}\n\n

Step 4: Update the variable

\n

Variables enable you to store and reuse values in Postman. We have created a variable called base_url which points to http://localhost:3000/v1/ assuming the web server is up.

This is a GET request and it is used to \"get\" data from an endpoint. There is no request body for a GET request, but you can use query parameters to help specify the resource you want data on (e.g., in this request, we have id=1).

\n

A successful GET response will have a 200 OK status, and should include some kind of response body - for example, HTML web content or JSON data.

This is a PUT request and it is used to overwrite an existing piece of data. For instance, after you create an entity with a POST request, you may want to modify that later. You can do that using a PUT request. You typically identify the entity being updated by including an identifier in the URL (eg. id=1).

A successful PUT request typically returns a 200 OK, 201 Created, or 204 No Content response code.
