Can anyone tell me how can I automate web WhatsApp to send msgs to every person in the contect list or suggest me a better option to do so, just remember I cant buy paid APIs.
you can use web.whatsapp.com url:
import webbrowser
import time
import pyautogui
phone = "12345678901"
text = "my message"
webbrowser.open(f"https://web.whatsapp.com/send?phone={phone}&text={text}&app_absent=0")
time.sleep(9) # wait for whatsapp web
pyautogui.click() # move your mouse to textbox before
pyautogui.press("enter")
