File contents

PostLake: schedule posts

Scheduling is the same as publishing, plus a scheduledAt timestamp. Prefer scheduling over immediate publishing when the user gives a time, so they can review the queue first. Address accounts exactly as in the postlake-publish skill: by profile (simplest, optionally narrowed with platforms) or by accounts ids.

Auth

Authorization: Bearer $POSTLAKE_API_KEY

Base URL https://api.postlake.dev.

Schedule a post

Send an ISO 8601 scheduledAt (UTC, or include an offset). It must be in the future. Convert the user's local time to UTC before sending.

curl -X POST https://api.postlake.dev/v1/posts \
 -H "Authorization: Bearer $POSTLAKE_API_KEY" \
 -H "Content-Type: application/json" \
 -H "Idempotency-Key: $(uuidgen)" \
 -d '{
  "text": "Weekly recap 👇",
  "profile": "my-brand",
  "scheduledAt": "2026-07-18T08:00:00Z"
 }'

The post comes back with state: "scheduled". It fires automatically at the time you set (no polling needed).

List scheduled posts

curl "https://api.postlake.dev/v1/posts?state=scheduled" \
 -H "Authorization: Bearer $POSTLAKE_API_KEY"

Reschedule or edit before it fires

curl -X PATCH https://api.postlake.dev/v1/posts/POST_ID \
 -H "Authorization: Bearer $POSTLAKE_API_KEY" \
 -H "Content-Type: application/json" \
 -d '{ "scheduledAt": "2026-07-18T09:30:00Z", "text": "Updated caption" }'

Only posts still in state: "scheduled" can be edited, and the new time must be in the future.

Cancel a scheduled post

curl -X DELETE https://api.postlake.dev/v1/posts/POST_ID \
 -H "Authorization: Bearer $POSTLAKE_API_KEY"

Tips

Always echo back the time in the user's local zone when confirming ("Friday 9:00am BST"), but send UTC to the API.
Media, per-platform captions, and platformOptions all work exactly as in the postlake-publish skill.
