# Partially Update a Bundle

**PATCH** `/bundles/{bundleSlug}/`

Partially update selected Bundle fields.

Allowed fields:
- `team`
- `expires`
- `cc_sender`
- `cc_emails`
- `send_reminders`
- `reminder_offset`
- `reminder_interval`
- `reminder_expires`
- `owner`

Notes:
- Only Bundles in `dr` (Draft) or `se` (Sent) status can be updated.
- Full updates (`PUT`) are not supported. Use `PATCH`.
- `owner` updates are restricted to account admins.
- `team` updates require the Teams feature.
- Reminder fields require the Reminders feature.
- For Sent (`se`) Bundles, updating `expires` changes the date while preserving the existing time-of-day.
