Update scheduled post

<Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

Edits the content or the schedule of a post that hasn't published yet. Send only the fields you want to change: an omitted field keeps its current value, and an empty body fails with a 400.

proposal and scheduled are the only editable states. Every other one answers 409 naming the state that blocked the edit: publishing while the publisher has the post, posted and failed once it's over, publish_outcome_unknown when the platform's answer was lost, and the needs_reconnect and not_materialized_plan_limit a scheduling run can leave behind. platform isn't editable in any state, because publishing to a different account is a new post rather than an edit.

<Note>Only the fields documented here are accepted, platform included, and any other field in the body fails with a 422. So don't read a post and send the whole object back: id, app_id, status, workflow_id and the rest of the response are Base44's, and a round-trip like that is rejected rather than partly applied. Send only the fields you're changing.</Note>

image_url and image_prompt are the only fields you can clear by sending null. A null for any other field fails with a 422.

Editing a post also takes over its content. A post generated from a content plan stops tracking that plan once you edit it, so regenerating the plan no longer overwrites what you wrote.

Editing scheduled_at only moves a post you haven't scheduled yet. A post that already carries a workflow_id is bound to the instant it had when you ran Start scheduling posts, and it publishes then even though the calendar reports your new time. Content edits always take effect, because the post is read again at publish time. To move a post that's already scheduled, delete it and create it again at the new time.

The social calendar endpoints share two rate limits: 20 requests per minute across creating, editing, deleting and approving posts, and 40 requests per minute across the rest. This endpoint counts against the 20.

<Note>This endpoint accepts a personal API key. Workspace API keys are not authorized for it and are rejected with a 403.</Note>

patch/api/apps/{app_id}/social-calendar/posts/{post_id}

Path parameters

post_idstring required

ID of the post, as returned by List scheduled posts.

ID of the post, as returned by List scheduled posts.

app_idstring required

ID of the app whose social calendar you want.

ID of the app whose social calendar you want.

Request body

titlestring nullable

New title for the post. Omit it to keep the current one; an explicit null fails with a 422.

bodystring nullable

New body text. Omit it to keep the current one; an explicit null fails with a 422.

scheduled_atstring date-time nullable

New publish time, as an ISO 8601 timestamp between the years 2000 and 2100. This only moves a post that isn't scheduled yet: once the post has a workflow_id it publishes at the time it was handed over with. An explicit null fails with a 422.

scheduled_timezonestring nullable

New IANA timezone for scheduled_local_at. It never moves the instant the post publishes. An explicit null fails with a 422.

hookstring nullable

New angle for the post. An explicit null fails with a 422.

best_time_reasonstring nullable

New reason shown alongside the post's time. An explicit null fails with a 422.

hashtagsstring[] nullable

Replacement list of up to 30 hashtags, without the leading #. Send [] to publish none; an explicit null fails with a 422.

image_urlstring nullable

New HTTPS image URL, or null to remove the image. Removing it from an Instagram post means the post is rejected when it publishes.

image_promptstring nullable

New image prompt, or null to clear it.

Example request

  "scheduled_timezone": "Asia/Jerusalem",
  "hook": "social_proof",

}

Response

The post after the edit.

idstring required

ID of the post. Pass it as post_id to the other social calendar endpoints.

app_idstring required

ID of the app the post belongs to.

plan_idstring nullable required

ID of the content plan the post was generated from, or null for a post created through Create scheduled post.

source_post_idstring nullable required

ID this post has inside the content plan it came from, or null for a post created through the API.

platformstring required

Account the post publishes to. Base44 publishes to instagram and linkedin. A post generated from a content plan can also name x, tiktok, reddit or facebook, which Base44 plans for but can't publish, and scheduling such a post fails it.

titlestring required

Title of the post. It labels the post on the calendar and isn't published as text, except on LinkedIn, where a post with an image sends it as the image's title.

bodystring required

Body text of the post. Base44 publishes this followed by hashtags, so leave the tags out of it.

hookstring required

The angle the post leads with. A plan-generated post carries the angle the planner picked, such as pain_point or social_proof; a post you create carries whatever you sent, or an empty string.

cover_indexinteger required

Zero-based position of the post in the series its content plan generated, which is how the calendar picks its cover image. Always 0 for a post created through the API.

scheduled_atstring date-time required

When the post publishes, always in UTC. A post read back from the calendar carries no offset (2026-09-15T14:00:00), while the one Create scheduled post returns carries +00:00. Read both as UTC.

scheduled_local_atstring required

The same instant as scheduled_at, rendered in scheduled_timezone as an ISO 8601 timestamp. Display only.

scheduled_timezonestring required

IANA timezone scheduled_local_at is rendered in. It never moves the instant the post publishes.

best_time_reasonstring required

Why this time was picked, written by the planner for a plan-generated post. Empty unless something set it.

hashtagsstring[] required

Hashtags published after body, without the leading #. A leading # you send is stripped before publishing.

image_urlstring nullable required

HTTPS URL of the image published with the post, or null if it has none. An Instagram post needs one to publish.

image_promptstring nullable required

Prompt the post's image was generated from, or null if there is none. Kept for reference; this endpoint doesn't generate images from it.

statusstring required

Where the post is in its lifecycle: proposal before you approve it, scheduled once approved, publishing while it's going out, then posted. needs_reconnect means the platform account has to be reconnected, not_materialized_plan_limit that the workspace plan doesn't cover publishing, publish_outcome_unknown that the platform may have accepted the post but Base44 couldn't confirm it, and failed that the post can't go out.

workflow_idstring nullable required

ID of the automation that publishes this post, set once Start scheduling posts hands it over, and null before that. Its presence is what tells you the publish time is fixed.
