# Checkout options

The endpoint identifies potential fulfillment locations and the fulfillment options available at each location (facility). This allows the shop to offer more detailed information about the upcoming fulfillment and provide additional services during the checkout process, such as specific carriers and delivery options.

At this stage, the specific facility or facilities that will ultimately be chosen for fulfillment are not determined, as this call only performs a partial routing without evaluating or ranking the facilities.

## Request and response <a href="#what-is-the-purpose-of-this-endpoint" id="what-is-the-purpose-of-this-endpoint"></a>

### Request

When querying "checkout options" a routing decision is made based on the [fences](https://docs.fulfillmenttools.com/documentation/by-pillar/advanced-order-routing/fences) that are configured in the [routing strategy](https://docs.fulfillmenttools.com/documentation/by-pillar/advanced-order-routing/routing-strategy).

The request is similar to the final order that would be submitted into the system but less information is mandatory.

### Response

The response includes all information on possible locations that have stock of at least one of the ordered items and have not been filtered out by [fences](https://docs.fulfillmenttools.com/documentation/by-pillar/advanced-order-routing/fences).

The response contains the following information:

* Facility data
  * General Information on the facility
  * Picking times and capacities (only for click & collect requests)
* Stock information
  * stock available within the facility (for ordered items)
* Carrier information
  * Active carriers
  * Available carrier products
  * Carrier costs
  * Carrier delivery times
