Sending Contacts
🔒 WhatsApp 24-Hour Session Rule
Before sending a contact, make sure the WhatsApp session with the user is active.
If the user has not messaged your business within the last 24 hours, WhatsApp requires the first message to be a template message.
After the customer replies, the 24-hour session opens and you may send contacts using this API. For sandbox testing, send your join code to the sandbox number to activate your session. Learn more
WhatsApp offers an API to send contacts.
