## Link Order to PO and Create Container Endpoints

We have added two new endpoints to our Rest API:

- [Link Order to PO (Crossdock)](/content/developer/dev-article/link-sales-order-to-po-crossdock/index.html) – consuming this endpoint allows you to [link a Sales Order](/content/help/omnichannel-ecommerce/link-an-order-to-a-po/index.html) to an existing Purchase Order or create a new one.
- [Create Shipping Container](/content/developer/dev-article/create-shipping-container/index.html) – this lets you create a single [PO Shipping Container](/content/help/omnichannel-ecommerce/purchase-orders-shipping-containers/index.html).
