# Bulk Update Threads

> Set read, starred or category on up to 100 threads in one call.

Requires an API key with the `write` scope.

Ids that are not in this workspace are skipped and not counted. Fields you leave out, or send as `null`, are not changed. Setting `category` to `unsubscribe` unsubscribes each affected lead and cancels their queued sends in every campaign; that cannot be undone. A category change writes an audit entry per thread and fires the `reply.categorized` webhook event.

## Body Parameters

<ParamField body="ids" type="string[]" required>
  Thread identifiers, 1 to 100.
</ParamField>

<ParamField body="isRead" type="boolean">
  Mark read or unread.
</ParamField>

<ParamField body="isStarred" type="boolean">
  Star or unstar.
</ParamField>

<ParamField body="category" type="string">
  New category. One of: `interested`, `not_interested`, `out_of_office`, `bounce`, `unsubscribe`, `uncategorized`, `unknown`, `unrelated`.
</ParamField>

## Response

## Rate Limit

- **100 requests per minute, shared by every `bulk` call in your workspace.** Fixed 60-second window.
- Every response includes `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset` (unix epoch seconds) and `X-RateLimit-Bucket` (`bulk`).
- A `429` response includes a `Retry-After` header (seconds until the bucket resets).
