How it works
Add Notes to the publishing workflow you already use
Substack is a publishing destination in Ferryman. Connect a session, choose Substack in an eligible flow or composed post, and keep creating at your normal origin.
- 01
Connect your Substack session
Provide the substack.sid value and your handle through Settings.
- 02
Choose Substack as a destination
Add Notes to an automatic flow, direct post, or schedule.
- 03
Reconnect when needed
Substack sessions can expire because Notes does not offer a public OAuth posting API.
Platform support
What Ferryman supports with Substack

02
Image Notes
Upload supported images and attach them to the Note.
03
Video Notes
Upload eligible video through Substack's processing pipeline up to 15 minutes.
04
Link attachments
Preserve links and attach the first eligible URL when the Note has no media attachment.
05
Self-reply continuations
Continue beneath a parent Note that Ferryman can resolve from the same flow.
06
Immediate and scheduled publishing
Include Substack in direct posts or prepare a Note for later.

Substack questions, answered
Does Ferryman publish to Substack Notes?
Yes. Ferryman can publish supported text, images, links, and videos as Substack Notes.
Can Substack be an automatic origin?
No. Ferryman publishes to Substack Notes but does not read a Notes feed as an automatic origin.
How does the Substack connection work?
Substack does not provide a public Notes posting API. Ferryman uses the substack.sid session cookie you provide, so you may need to reconnect when that session expires.
Do replies and reposts work?
Reposts are not supported. A self-reply continuation can publish beneath a Note when Ferryman can resolve the parent Note created by the flow.
Can I tailor content for Substack?
Yes. Add a per-target prompt or filter to expand context, change tone, or skip posts that do not fit your Notes audience.
