WhatsApp will today begin beta testing a new, cloud-based version of its WhatsApp Business API, hosted on parent company Facebook's infrastructure. With the shift to the cloud, the setup time for integrating with the API will drop from weeks to only minutes, the company claims, so businesses can more quickly transition to WhatsApp's API platform to communicate with their customers who have opted in to receive their messages.
