Sending automatic birthday wishes on WhatsApp

Here is an example of how it can be done: Register for a WhatsApp Business API account. Create a new project in the WhatsApp Business API, and obtain the necessary credentials such as the Account SID and Auth Token.

Create a new Blogger page and embed an HTML form that allows users to input their WhatsApp number and date of birth. Use the WhatsApp Business API to send a message to the user's WhatsApp number on their birthday.

import requests import datetime  # WhatsApp Business API credentials account_sid = "your_account_sid" auth_token = "your_auth_token"  # Employee information employees = {     "John Doe": "01/01/2000",     "Jane Smith": "02/15/2001",     "Bob Johnson": "03/05/2002" }  # WhatsApp Business API endpoint endpoint = "https://api.whatsapp.com/v1/messages"  def send_whatsapp_message(to, message):     headers = {         "Authorization": f"AccountSid {account_sid}",         "Content-Type": "application/json"     }     data = {         "from": "whatsapp:+14155238886",         "to": f"whatsapp:{to}",         "body": message     }     requests.post(endpoint, headers=headers, json=data)  while True:     for name, dob in employees.items():         today = datetime.datetime.now()         # check if it's the employee's birthday         if today.strftime("%m/%d") == dob.strftime("%m/%d"):             message = f"Happy birthday, {name}! Have a great day!"             send_whatsapp_message(employees[name], message)     # Sleep for a day     time.sleep(60*60*24)

This script uses the requests library to send messages to the WhatsApp Business API. It uses a dictionary to store the names and dates of birth of the employees. It then uses a while loop to continuously check the current date against the dates of birth in the employees list, and sends a message wishing the employee a happy birthday if it's their birthday,

The script sleeps for a day between each check so that it doesn't continuously check for birthdays throughout the day. It's important to note that this code is a basic example and you should also be aware of the limitations of WhatsApp Business API and also the requirement of obtaining a phone number that is approved by WhatsApp to send messages. You should also be aware of the privacy and GDPR regulations.
