Autochat's WhatsApp API Sandbox provides you a development environment without any container infra setup like WhatsApp. Just register and your WhatsApp Business API Sandbox will be immediately ready for use.
It provides APIs and webhooks that are exactly same as WhatsApp Business API. When you are ready for production use, setup WhatsApp Business Client and replace hostname and you are ready! This avoids triggering actual WhatsApp messages during development or pre production.
Sandbox provides messenger interface for mobile's WhatsApp screen. You can send and receive messages to and from Sandbox on single screen easily and quickly. No need to maintain multiple WhatsApp accounts on multiple devices.
