All Twilio customers can build and test sending and receiving WhatsApp messages using our WhatsApp Sandbox.
However, in order to use your own WhatsApp brand, phone number(s), and message templates through Twilio, your use case must be reviewed and approved by WhatsApp. Twilio is working directly with WhatsApp to handle approvals for our customers. As of early 2019, approvals are in limited availability, so many customers are still testing with the Sandbox.
- For help getting started with building and testing in the WhatsApp Sandbox, please see Getting Started with Twilio for WhatsApp (Beta).
- To be notified as WhatsApp further opens up approvals for using your own Twilio numbers and templates, sign up for updates here: Request to enable your Twilio numbers for WhatsApp.
Notice: Twilio strongly recommends that customers launch WhatsApp capabilities in stages. If you expect rapid adoption by over 1,000 unique users on your first day, please try a more gradual roll-out of your WhatsApp capabilities. For more information, please see WhatsApp Rate Limiting.
