On August 26th, all old names will be retired and your API calls will need to be updated with the new names. Any API automation still using an old names will result in an error.

The following locations have been updated with the latest WebPageTest agent version; with this version update we have also updated the agent names, please take note of the new agent name and make any necessary changes to your API automation as the existing agent name will be retired. Current agent names will be mapped to the new name until retirement.

In this guide, we'll walk you through the process of getting up and running with you very first API test.

1. Get your API Key

Once created, your API keys are always available in your account dashboard, under API Consumers.

If you can't see any API Keys, that means you don't currently have any and you will need to create a new one.

2. Submit your first test

To make sure your API key is ready to go, let's get your first test submitted. It takes some time for a test to complete.

Copy and paste the following command into your terminal, inserting your api key in place of the placeholders:

curl --request POST --url '' --header 'X-WPT-API-KEY: {YOUR_API_KEY}'

The request above will:

If all goes well, you should get a JSON response, similar to the one below, telling you the test has been successfully submitted (statusCode=200), and providing you with the testId as well as several links for digging into results once the test has been completed.

"statusCode": 200,
"statusText": "Ok",
"data": {
"testId": "210328_XiVQ_b694021b2a24ca1912dae50fb58b5861",
"jsonUrl": "",
"xmlUrl": "",
"userUrl": "",
"summaryCSV": "",
"detailCSV": ""

3. Navigate to the result page

All that's left is to view the test result!

If you go to the "userUrl" from the JSON result, you will see the normal "Test waiting" page that will refresh and load the test results when it completes. If you navigate to the "jsonUrl" in a browser you should see a JSON view of the test status. If you refresh the page periodically you will see the status change until it finally returns the full test result as JSON.

What comes next?

Congratulations! You've just successfully submitted your first test using the WebPageTest API. Here's a few more resources to help you take your next steps:
