How to Make PUT Request in Postman: Step-by-Step Guide

To make a PUT request in Postman, select PUT from the HTTP method dropdown, enter the request URL, add any required headers and body data, then click Send. Postman will execute the request and show the response below.

Syntax

A PUT request updates a resource at a specified URL. In Postman, you set the HTTP method to PUT, enter the URL, add headers like Content-Type, and provide the data to update in the request body.

• HTTP Method: PUT
• URL: The endpoint where the resource exists
• Headers: Metadata like content type (usually application/json)
• Body: The data to update, usually in JSON format

http

PUT https://api.example.com/resource/123
Headers:
  Content-Type: application/json
Body:
  {
    "name": "New Name",
    "status": "active"
  }

Example

This example shows how to update a user's name and status using a PUT request in Postman.

json

{
  "name": "John Doe",
  "status": "active"
}

Output

HTTP/1.1 200 OK
{
  "id": 123,
  "name": "John Doe",
  "status": "active"
}

Common Pitfalls

• Forgetting to set the HTTP method to PUT and leaving it as GET or POST.
• Not adding the correct Content-Type header, causing the server to reject the body.
• Sending an empty or malformed JSON body.
• Using the wrong URL or missing resource ID in the URL.
