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

Fixing Chrome Alerts for 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

Using 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 do 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 is no alert?
4. To address cases where the alert is not present, enclose the 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 do 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 know if a file was successfully uploaded to the server?
10. Check to see if a confirmation box or other element appears once the file has been successfully uploaded.
11. How should exceptions be handled in Selenium scripts?
12. Try-catch blocks are used to manage errors and provide helpful error messages or other actions in the catch block.
13. Can I use a different computer language to automate WhatsApp Web?
14. Yes, Selenium WebDriver supports a range of languages, including Python, Java, and JavaScript, allowing you to automate WhatsApp Web in your own language.
15. How should the phone numbers in my script 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. How can I ensure that my script waits until the complete page has loaded?
18. Before dealing with elements, ensure that the page has completely loaded by using implicit or explicit waits.
19. What happens when a component is missing from the page?
20. Make that the element is on the page and that the correct XPath or CSS selector is being used. Use waits to handle dynamic content loading.
