# Update Purchase Orders
Update purchase orders. This operation updates existing purchase orders with the provided data.
### Beta
This API is a beta feature and is subject to possible changes. The API response and functionality will be updated in the future.
| Request limit | Record limit | Batch size |
| -------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------- | ------------------------------- |
| 500 requests per minute per organization
2,500 per minute per holding | 120 records per minute per organization (burst 1,000)
150 per minute per holding (burst 1,500) | Maximum 100 records per request |
Both limits are evaluated on every request. A request is rejected when either is exceeded.
For requests containing the maximum of 100 records:
* Following an idle period, 10 consecutive requests are accepted without delay. This corresponds to the 1,000-record burst allowance.
* Sustained submission is subsequently paced at one request per 50 seconds, approximately 1.2 per minute.
* The allowance is restored to its ceiling after approximately 8 minutes without submissions.
