Looking for the steps/actions to create an automation to post content written in drafts into a discord channel.
There is no native support and n pool existing examples for Discord posted to the directory, so you would need to build your own action to do so.
To communicate with Discord you would need to interact directly with the API.
Their docs on that are here.
You would then use an API call you code into a script step in a Drafts action to interact with it.
I would suggest looking in the directory to get other examples on interacting with API, and definitely do look to use credentials with your action.
Hope that helps.
