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.
