Post Callbacks
Automate follow-up actions when you publish or schedule posts: auto-share to other accounts, post follow-up comments (or thread posts on some networks), or auto-delete/hide content after specified conditions are met.
Overview
Post callbacks are automation features you include per-account in the API request when creating posts. Callbacks are configured inside each accounts[] entry. The main callback types:
AutoShare — automatically share a published post to other social accounts
Follow-up Comments — schedule one or multiple comments (or threaded posts) tied to a post
Auto-Delete / Auto-Hide — automatically remove or hide posts after conditions are met
Conditions are represented with a structured conditions object (relation + clauses) and can combine Time (age), Reach and Engagements checks using AND/OR.
Endpoints
Schedule with callbacks:
POST /api/v1/posts/schedulePublish now with callbacks:
POST /api/v1/posts/schedule/publish
Callbacks live inside each account object in your request payload.

Conditions object
Use conditions to define when a callback should execute.
Structure:
conditions
relation: "AND" | "OR"
clauses:
age: { duration: number, unit: "Minute" | "Hour" | "Day" | "Week" }
engagements: { comparison: "gt" | "lt", value: number }
reach: { comparison: "gt" | "lt", value: number }
Notes:
agecorresponds to "Is older than".engagementsandreachusecomparisonwith "gt" (>) or "lt" (<).A
conditionsobject can include any subset of clauses; combine them usingrelation.
Auto-Sharing
Automatically share the link of the published post to the specified accounts.
Fields:
share.account_ids (string[]) — target account IDs to share to
share.text (string) — caption for the share (fallback: original post text where supported)
share.conditions (object) — when the share should run (see Conditions object)
share.account_ids order +
delaydetermine spacing between shares
Example:
"share": {
"account_ids": ["A_ID_1", "A_ID_2"],
"text": "Check out our latest blog post!",
"conditions": {
"relation": "AND",
"clauses": {
"age": { "duration": 1, "unit": "Hour" },
"engagements": { "comparison": "gt", "value": 10 },
"reach": { "comparison": "gt", "value": 100 }
}
},
"delay": {
"duration": 0,
"unit": "Minute"
},
}Supported networks: Facebook Pages→Groups (when posting as a Page to a Group), Twitter/X, LinkedIn, Pinterest, Mastodon, Threads, BlueSky, TikTok, Telegram, Google Business Profiles.
Note: Google Business Profiles require non-empty text to auto-share.
Follow-up Comments
Schedule comments on the published post (or create follow-up posts/threads on some networks).
Fields:
comments[]:
text (string) — comment body (text, hashtags, links, emoji)
language (string, optional)
media (object, optional):
media.id: id of the media
media.path: URL / path
media.caption (optional)
media.thumbnail (optional, videos)
conditions (object, optional) — when to post the comment (see Conditions object)
Notes and behavior:
On Twitter/X, Mastodon, BlueSky, and Threads the follow-up comment will be posted as a new post in the thread.
Supported: Twitter/X, LinkedIn, Facebook Pages, Mastodon, Threads, BlueSky.
Not supported (API limitations): Pinterest, TikTok, Facebook Personal Profiles, Google Business Profiles.
Recurring posts: Configure follow-up comments at scheduling time to have them included for each recurrence.
Performance-based conditions (reach/engagements) and time-based (age) commonly apply to the first comment; subsequent comments use time-based
ageonly.
Example:
"comments": [
{
"text": "First 100 customers get 10% off!",
"conditions": {
"relation": "AND",
"clauses": {
"age": { "duration": 2, "unit": "Hour" },
"engagements": { "comparison": "gt", "value": 10 },
"reach": { "comparison": "gt", "value": 10 }
}
}
},
{
"text": "24 hours left—don’t miss out!",
"conditions": {
"relation": "AND",
"clauses": {
"age": { "duration": 1, "unit": "Day" }
}
},
"media": {
"id": "680fa5cc48487c4ccbf8c146",
"path": ".../photos/680fa5cc48487c4ccbf8c146.jpg",
"thumbnail": ".../photos/thumb_680fa5cc48487c4ccbf8c146.jpg",
"caption": "Only one day left!"
}
}
]Auto-Delete / Auto-Hide
Automatically delete or hide a post when conditions are satisfied.
Fields:
delete.conditions (object) — conditions triggering deletion/hide (see Conditions object)
Use
conditions.clauses.ageto set minimum time before deletion
delete.hide (boolean) — true to request hide instead of delete (platform-dependent)
Example:
"delete": {
"conditions": {
"clauses": {
"age": { "duration": 7, "unit": "Day" },
"engagements": { "comparison": "lt", "value": 10 }
}
},
"hide": false
}Supported / unsupported:
Auto-delete supported for most scheduled networks except:
Not available for Instagram API (auto-delete not supported)
Not available for TikTok accounts
Not available for posts published via reminders or some push/published types
Some types (e.g., Stories) cannot be auto-deleted
Auto-hide only works where supported (e.g., Facebook Page posts (not videos), YouTube)

}Best practices
Use performance-based
conditionsto avoid premature callbacks (e.g., only share if the post reached a threshold).Respect audience time zones when scheduling shares and comments.
Space out repeated shares across accounts using
share.delayto avoid spam signals.Prefer hiding (when supported) to preserve analytics/history if you may need them later.
Test callback behavior on target networks (APIs and behavior differ per platform).
Recurring posts & Post Presets
Recurring posts: add callbacks during scheduling so each recurrence includes them automatically.
Post Presets: configure default follow-up comments, auto-share targets, and default auto-delete/hide rules in Post Presets inside Publer. Presets use the same
conditionsmodel.
Limitations & notes
Some networks convert comments into separate posts/threads (Twitter/X, Mastodon, BlueSky, Threads).
Follow-up comments are not supported by Pinterest, TikTok, Facebook Personal Profiles, and Google Business Profiles due to API limitations.
Auto-delete is not available for Instagram, TikTok, posts published via reminders, or some story formats.
Performance-based conditions depend on platform metrics; metrics may arrive with delay.
