Hello everyone,
We have released a free WhatsApp Messaging by WhatsBox plugin for Bubble.
With this plugin you can initiate WhatsApp template messages to your target audience from your Bubble app using the workflow.
It enables two-way conversations with your users/customers using the WhatsBox Inbox. For example, you send an order confirmation from your Bubble app, which is also visible in your WhatsBox Inbox. When your user/customer replies to that message, it shows up in the WhatsBox Inbox, from where you can continue the conversation.
