How to pass custom headers with Appium mobile tests on LambdaTest?

2

Hey Emma,

You can add custom headers using LambdaTest’s customHeaders capability.

Shown below is a snippet where we are changing the user-agent via customHeaders capability.

customHeaders.put("user-agent", "Mozilla/5.0 (Linux; Android 14.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Mobile Safari/537.36");
ltOptions.put("customHeaders", customHeaders);

This is the complete setup given below for better understanding on how you can add custom header:

DesiredCapabilities capabilities = new DesiredCapabilities();
HashMap<String, Object> ltOptions = new HashMap<String, Object>();
ltOptions.put("w3c", true);
ltOptions.put("deviceName", "Galaxy.*");
ltOptions.put("platformName", "android");
ltOptions.put("platformVersion", "13");
ltOptions.put("isRealMobile", true);
ltOptions.put("network", true);
ltOptions.put("build", "Java Selenium 4");
ltOptions.put("name", "Sample Test Java");
ltOptions.put("network", true); //PLEASE ADD THIS CAPABILITY AS WELL

Map<String, String> customHeaders = new HashMap<>();
customHeaders.put("user-agent", "Mozilla/5.0 (Linux; Android 14.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.0.0 Mobile Safari/537.36");
ltOptions.put("customHeaders", customHeaders);

capabilities.setCapability("LT:Options", ltOptions);

driver = new AndroidDriver(new URL("https://username:access_key@mobile-hub.lambdatest.com/wd/hub"), capabilities);

driver.get("https://useragentstring.com/");

For additional details, refer to the LambdaTest Appium Custom Header support documentation.
