## Before You Begin

Before you get started with the WhatsApp Business API (WABA) setup, make sure you have the following ready:

✅ **Phone Number**: Keep your business phone ready to receive the OTP. If you don’t have one, you can get a **free testing sandbox number** from Facebook — just tap *Login with Facebook* and choose *Get Free Number*.

✅ **Remove Existing WhatsApp**: If you’re using WhatsApp on this number, back up your data and delete the account from your device.

✅ **Facebook Business Manager**: Make sure you have access to your Facebook Business Manager.

✅ **3Sigma Ultimate Plan**: You must be on the 3Sigma Ultimate Plan to use the WhatsApp Business API.

✅ **Website & GST**: A working website and valid GST number are **mandatory** for WhatsApp API approval.

✅ **Migration**: Moving from another provider? Don’t worry — your settings and templates will be migrated. Remove two-factor authentication (2FA) before setup.
