You have to provide a message `type` which has to be `note`, `link`, or `address`. The message types `checklist`, and `file` are not supported at the moment. Depending on the message `type` you can use additional fields: * note: `title` and `body` * link: `title`, `body`, and `url` * address: `name`, and `address` In every value of the options hash you can use the liquid templating, learn more about it at the [Wiki](https://github.com/cantino/huginn/wiki/Formatting-Events-using-Liquid).
