How to add headers or parameters to an HTTP request handled with Selenium Webdriver?

You can try evaluating browsermob-proxy. It helps in manipulating the headers.https://github.com/webmetrics/browsermob-proxy. Integrating with webdriver is simple. You just need to start the driver with the proxy values set.

This is how I fixed the problem in my case. Hopefully, might be helpful for anyone with a similar setup.

1. Add the ModHeader extension to the chrome browser

How to download the Modheader? Link

ChromeOptions options = new ChromeOptions();options.addExtensions(new File(C://Downloads//modheader//modheader.crx));// Set the Desired capabilities DesiredCapabilities capabilities = new DesiredCapabilities();capabilities.setCapability(ChromeOptions.CAPABILITY, options);// Instantiate the chrome driver with capabilitiesWebDriver driver = new RemoteWebDriver(new URL(YOUR_HUB_URL), options);

2. Go to the browser extensions and capture the Local Storage context ID of the ModHeader

3. Navigate to the URL of the ModHeader to set the Local Storage Context

.

// set the context on the extension so the localStorage can be accesseddriver.get("chrome-extension://idgpnmonknjnojddfkpgkljpfnnfcklj/_generated_background_page.html");Where `idgpnmonknjnojddfkpgkljpfnnfcklj` is the value captured from the Step# 2

4. Now add the headers to the request using Javascript

.

   ((Javascript)driver).executeScript(         "localStorage.setItem('profiles', JSON.stringify([{  title: 'Selenium', hideComment: true, appendMode: '',              headers: [                                       {enabled: true, name: 'token-1', value: 'value-1', comment: ''},               {enabled: true, name: 'token-2', value: 'value-2', comment: ''}             ],                                       respHeaders: [],             filters: []          }]));");

Where token-1, value-1, token-2, value-2 are the request headers and values that are to be added.

5. Now navigate to the required web-application.

   driver.get("your-desired-website");
