There is no Patreon API import in Yaff. A move is a communication and checkout exercise: stand up tiers, tell patrons, and optionally gift a free pass so they are not charged twice in the overlap month.
The growth move is a plain URL. Yaff’s YouTube connection is for pulling comments into the dashboard — it does not publish videos to YouTube or add the link for you.
There are no Instagram or TikTok fields or OAuth integrations on a Yaff profile. Link-in-bio is you pasting the URL in those apps.
There is no goal, thermometer or campaign object in the product. Expedition funding on Yaff is an ongoing membership plus the story, not a one-off target.
