Sorry for the late reply. Do these posts need to be published immediately? Since we don’t yet offer a WordPress trigger, you’d have to set up a webhook in wordpress yourself and use that to start your workflow.
If timing is a little less sensitive, you can use the ‘Get Many’ operation and add an option to sort by Date to get the most recently published blogpost.
A caveat here is that if you run this workflow again before publishing a new blogpost, you will end up getting the same article published on Medium, so you’d have to add some guardrails for that.
