Why you need to add a WhatsApp button to your website and social media accounts
Stay in contact with customers even after they leave: adding a WhatsApp button to your social media accounts and website is an efficient way to stay connected with customers, even after they leave your website or social media page. Adding this button enables customers to reach you quickly and allows you to collect their contact information.
Better response time: the WhatsApp button allows you to interact with your customers in real-time and quickly, mainly because the app is constantly used and messages are read within seconds of receipt, unlike emails. Also, with multiple agents at the backend of your WhatsApp API account, massive incoming inquiries are easily managed.
Take advantage of the 72 hours window of free conversation: for WhatsApp API users, starting March 1, 2023, WhatsApp's messaging window for businesses increased from 24 to 72 hours when customers use the WhatsApp button on your social media accounts. Messages exchanged during this period will not be charged, regardless of the template type used. You can use marketing, service, utility, and authentication template messages without opening a new conversation.
To take advantage of the benefits of a WhatsApp button for your online store, you must first meet a few requirements. Here’s what you need:
A WhatsApp Business account: you cannot set up a WhatsApp button on your social media accounts using WhatsApp Messenger. You must have a business account. However, you can use WhatsApp Messenger for the website button.
Social media pages: you need social media pages for your business. You cannot use personal profiles.
You must link your WhatsApp account to your social media pages.

Note that you can use the WhatsApp button regardless of whether you use a WhatsApp business account or a WhatsApp API account.
