Using Postman (No Code Required)

Run In Postman

What You'll Need

Step-by-Step Guide

Download and Open Postman

Download Postman from postman.com/downloads and install it. Create a free account or skip sign-in to continue.

Create a New Request

  1. Click the + button to open a new request tab
  2. Make sure GET is selected in the dropdown (it's the default)

Enter the API URL

Paste this URL into the request field:

https://api.whitepages.com/v1/person?name=John%20Smith&city=Seattle&state_code=WA

Add Your API Key

  1. Click the Headers tab below the URL field
  2. In the Key column, enter: X-Api-Key
  3. In the Value column, paste your API key

Header Name is Case-Sensitive

Make sure to use X-Api-Key exactly as shown, with capital X, A, and K.

Send the Request

Click the Send button. You should see a JSON response in the panel below.

Example Response
[
  {
    "id": "P1234567890",
    "name": "John Smith",
    "current_addresses": [
      {
        "address": "123 Main St, Seattle, WA 98101"
      }
    ],
    "phones": [
      {
        "number": "(206) 555-0198",
        "type": "mobile"
      }
    ]
  }
]

If you see data like this, your API key is working correctly.

Using cURL (Command Line)

If you prefer the command line, you can use cURL:

curl 'https://api.whitepages.com/v1/person?name=John%20Smith&city=Seattle&state_code=WA' \
  --header 'X-Api-Key: YOUR_API_KEY'

Replace YOUR_API_KEY with your actual API key.

Troubleshooting

403 Forbidden or "Invalid API Key"

  • Double-check that you copied the entire API key from your email
  • Verify the header name is exactly X-Api-Key (case-sensitive)
  • Make sure there are no extra spaces before or after your API key

No Results Found

A 404 response with no results is normal—it means your API key is working, but no records matched your search. Try different search parameters.
