Matter Most Incoming Webhook
Matter Most output node.
Expects a msg.payload with a string that will be posted to the channel.
This can be found on the Incoming WebHooks for the channel of your choice.
This is the name that will appear above each post to the channel
This is the emoji that will be dispalyed next to each of the messages in the channel. this can be a url of your choice, but it must be a full url.
You can optionally override the destination channel if required - either in the edit dialogue or by setting msg.channel.
You can also create Matter Most attachments by adding a msg.attachments property that must be an array. Unset the payload to make it even smaller.
For more information see Matter Most Incoming Webhooks.
