How to create workflow with Custom workflow action?

Hi @SSun7
Thank you for reaching out to the Community! Just to clarify—are you asking if there’s a way to set up a workflow using the custom action you’ve already built via a custom action endpoint, or are you looking for guidance on how to create the custom action itself?
I’d like to invite some community members who are subject matter experts to join this conversation.
@SteveHTM @MichaelMa @nickdeckerdevs1 - Would you be able to share any insights on this? Your expertise would be greatly appreciated.
Best,
Victor
