How to Automate WhatsApp Web: Managing Alerts with C# and Selenium

Fixing the Chrome Alert for the C# WhatsApp Web Automation

Using Selenium WebDriver in a C# script

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using OpenQA.Selenium.Support.UI;
using System;
using System.Windows.Forms;

public void button2_Click(object sender, EventArgs e)
{
    string telefonNumarasi = maskedTextBox1.Text;
    telefonNumarasi = telefonNumarasi.Replace("(", "").Replace(")", "").Replace(" ", "").Replace("-", "");
    string temizTelefonNumarasi = telefonNumarasi;
    label1.Text = temizTelefonNumarasi;
    string BASE_URL2 = "https://api.whatsapp.com/send/?phone=90" + temizTelefonNumarasi + "&text&type=phone_number&app_absent=0";
    IWebDriver driver = new ChromeDriver();
    driver.Url = BASE_URL2;
    driver.Navigate().GoToUrl(BASE_URL2);
    driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(10);
    try
    {
        // Dismiss alert if present
        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(5));
        wait.Until(ExpectedConditions.AlertIsPresent());
        IAlert alert = driver.SwitchTo().Alert();
        alert.Dismiss();
    }
    catch (NoAlertPresentException)
    {
        // No alert present, continue
    }
    try
    {
        IWebElement sohbeteBasla = driver.FindElement(By.XPath("//*[@id=\"action-button\"]"));
        sohbeteBasla.Click();
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

Overcoming WhatsApp's Web Automation Obstacles

Utilizing Selenium WebDriver in a Python script

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import NoAlertPresentException
import time

def send_whatsapp_message(phone_number):
    url = f"https://api.whatsapp.com/send/?phone=90{phone_number}&text&type=phone_number&app_absent=0"
    driver = webdriver.Chrome()
    driver.get(url)

    try:
        # Dismiss alert if present
        WebDriverWait(driver, 10).until(EC.alert_is_present())
        alert = driver.switch_to.alert
        alert.dismiss()
    except NoAlertPresentException:
        # No alert present, continue
        pass

    try:
        sohbete_basla = WebDriverWait(driver, 10).until(
            EC.element_to_be_clickable((By.XPATH, '//*[@id="action-button"]'))
        )
        sohbete_basla.click()
    except Exception as e:
        print(f"Error: {e}")

    time.sleep(5)
    driver.quit()

# Example usage
send_whatsapp_message("5551234567")

Frequently Asked Questions and Answers for Web Automation with WhatsApp

1. How should I use Selenium WebDriver alerts?
2. Make use of driver.SwitchTo().To shift the emphasis to the alert and alert, use Alert().To dismiss it, use dismiss().
3. What happens if there isn't an alert?
4. To handle situations where the alert is not present, encapsulate the alert handling code in a try-catch block and catch NoAlertPresentException.
5. How long can I wait for a clickable element to appear?
6. To wait for the element to be clickable, use WebDriverWait in conjunction with ExpectedConditions.elementToBeClickable().
7. How can I use Selenium to upload a file?
8. Find the file input element, then enter the file path directly into it by using SendKeys().
9. How can I confirm that a file was successfully uploaded to the server?
10. Verify whether a confirmation window or other element displays following the successful upload of the file.
11. How should exceptions be handled in Selenium scripts?
12. To manage errors and offer informative error messages or other actions in the catch block, use try-catch blocks.
13. Can I use another computer language to automate WhatsApp Web?
14. Yes, you may automate WhatsApp Web in the language of your choice thanks to Selenium WebDriver's support for a variety of languages, including Python, Java, and JavaScript.
15. How should my script's phone numbers be formatted and cleaned up?
16. Before utilizing the phone number in the URL, remove any extraneous characters by using string replacement techniques like Replace().
17. In what way can I make sure my script waits for the entire page to load?
18. Before interacting with elements, make sure the page has fully loaded by using implicit or explicit waits.
19. What happens if a component is missing from the page?
20. Make sure the element is on the page and that the appropriate XPath or CSS selector is being used. To manage the loading of dynamic material, use waits.
