Twilio eliminates the operational overhead of integrating directly with the WhatsApp messaging network, which requires hosting, managing, and scaling containers in your own cloud infrastructure. WhatsApp containers manage encryption keys and messages between the business and users, enabling WhatsApp to provide end-to-end encryption of messages. These containers must be hosted in multiple regions to ensure high availability and efficient scaling as messaging volume increases. Twilio removes this complexity to provide you with a simple and reliable REST API.
Additionally, regardless of your use case, you need to philippines mobile number example build in certain features, such as managing user subscriptions (opt-in) and accepting unsubscribe requests (opt-out). To ensure important notifications are always delivered, you need to be able to switch to SMS if the user can’t be contacted on WhatsApp due to app uninstallation or poor data connectivity. Twilio provides these features out-of-the-box, reducing the amount of custom code you need to write.
