Unified CLI

Global options such as --json, --cookies, and --publication-url must appear before the command.

Create an unpublished draft

substack drafts create post.md

The title comes from the first Markdown heading, then the filename if the file has no heading. Use --title to override it.

Export a draft to Markdown

Print a read-only Markdown backup to standard output:

substack drafts export 12345

Write it to a UTF-8 file:

substack drafts export 12345 --output backup.md

The command refuses to replace an existing file unless --force is present. It fetches the draft but performs no server writes. Content without a supported Markdown representation is emitted as a versioned opaque HTML comment instead of being silently discarded.

Select a publication

List every publication available to the authenticated account:

substack publications list

Select one for a single command:

substack --publication-url https://example.substack.com drafts list

Schedule an existing draft

Pass an ISO 8601 timestamp with a timezone offset or Z:

substack drafts schedule 12345 --at 2030-01-02T09:00:00+01:00

Remove the schedule without deleting the draft:

substack drafts unschedule 12345

Stable JSON for automation

substack --json drafts list --limit 10
substack --json drafts export 12345

The command writes a JSON object containing drafts, count, filter, offset, and limit. Errors are also JSON when --json is present. Export JSON contains action, draft_id, markdown, and unsupported_nodes.

Publish and delete

substack drafts publish 12345 --no-send
substack drafts delete 12345 --yes

Publishing and deletion require confirmation. JSON and noninteractive workflows must pass --yes. Publishing runs Substack’s prepublish check first. See safety and publishing behavior.

The original console scripts remain supported. See legacy CLI commands.
