BookMyShow uses WhatsApp Business API to send text messages, including ticket confirmations and updates, but it does not "decrypt" the API. Instead, it interacts with the API through secure, authorized channels provided by Meta (WhatsApp's parent company).
Here’s how it works:
API Integration: BookMyShow integrates with the WhatsApp Business API, which enables sending messages to users securely.
End-to-End Encryption: Messages sent via WhatsApp remain end-to-end encrypted. BookMyShow doesn’t decrypt these messages; it simply provides the content that WhatsApp encrypts for delivery.
Third-Party Providers: They may use authorized providers like Twilio or CEQUENS to streamline API usage and ensure compliance with WhatsApp's policies.
The focus is on secure transmission, not decryption.
