Guide to using and optimizing WhatsApp protocol number generation tool in South Korea

When operating WhatsApp business in the Korean market, have you encountered compatibility issues with the protocol number generation tool? When our team was debugging tools for local beauty customers, we found that the generated protocol numbers were frequently intercepted by the system.
