Hello,

1. The price for using the solution is free. Node-RED is an open-source project that you can download and run or host on your computer. They also offer a hosted solution. When it comes to Sinch Conversation API, you can read more about the pricing here: https://www.sinch.com/conversation-api/#pricing_api. It has a free tier and a few monthly payment plans. It also depends on which channels you want to use. FB Messenger is free for example, but SMS requires a paid number and has a cost associated with sending messages.

2. The Conversation API does in fact support WhatsApp as well. Messages are created in an OMNI format, meaning that there is one format you specify the messages in and the Conversation API will translate that into each different messaging channel. You can either create an OMNI template using the "Message composer" in the Sinch dashboard. These will then be available to select in the Template node. Or you can specify a "raw" JSON formated message using the Message node.

I hope this answers your questions!
