Refresh Segment
refresh_segmentRe-derive a single stale or expired segment from the current IAG. Updates ONLY the segment — referencing audiences are never touched; the response lists them in affected_audiences so you can recount or refresh them (use refresh_audience for a whole-composition refresh). Behaviour is subtype-specific:
filter: synchronous — bumps current_version, nulls record_count, resets the 90-day TTL, returns status: active. If the segment is already fresh the call is a no-op (refreshed: false); pass force: true to bump anyway. Call count_segment afterwards for a fresh count.
matched: with hitl false/unset (default): returns status: pending + upload_url (24 h presign) targeting the canonical upload path — or upload_urls (an array) when shard_count > 1 — instruct the user to re-upload their identity list (one same-format file per URL for a sharded upload; every CSV shard needs its own header); identity resolution runs automatically once all shards are uploaded. Then call wait_for_segment(segment_id). With hitl: true: the upload is staged instead — after upload, follow the analyze_audience_upload -> confirm_column_mappings / cancel_matched_upload -> wait_for_segment sequence documented on create_segment(subtype=matched). Returns 409 SHARED_SOURCE_DATA for matched duplicates that reference another segment's data — the message names the source segment to refresh instead.
custom: immutable snapshot; returns 409 CUSTOM_REGENERATION_REQUIRED. Request a new internal data-team publication. Returns 409 SEGMENT_ARCHIVED for archived segments — restore them first with archive_segment(restore=true). Async build completion or failure may notify configured external webhooks and opted-in users by email. Requires 'creator' scope.

}Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| hitl | No | If true: stages a matched segment's re-upload instead of resolving automatically. Defaults to false. | |
| force | No | Filter subtype only: bump the version even when the segment already looks fresh. Defaults to false. | |
| segment_id | Yes | The segment ID to refresh | |
| compression | No | Matched subtype: replacement upload compression. | none |
| shard_count | No | Matched subtype: set > 1 for multiple same-format shards. |
