The main message of the feed can be edited through Discord with the command text. Regular Markdown formatting is possible wherever Discord allows, and of course placeholder use is supported.
"{date}\nA new feed has arrived!\n\n**{title}**\n{description}"
If you want to add links to your feed but do not want the embed that Discord creates, such as the one in the image below:
Add < and > around your link. This also applies for use with placeholders (for example, <{link}> ).


"title": "some title",
"url": "",
"channel": "12345",
"text": "My Message here!"
