List time slots for pickup

POST /v2/fulfillment/users/{user_id}/service_options/cart/pickup

Lists the available pickup service options for the customer's location and cart items. In this context, service options are time slots, such as Within 5 hours or Friday 9am-11am. Availability is based on current and anticipated shopper availability for the relevant store location. The list includes immediate and scheduled time slots.

After a time slot is selected, save the service_option_id. You specify the ID when reserving the time slot.

Best practice

Include all the items in the cart in the request. Connect can surface any errors—such as items missing from the catalog—early in the user flow and also precompute some validations to optimize performance.
