# Pick-At-Store (PAS) Model

The Pick-At-Store (PAS) Model allows customers to place orders directly in-store and receive their items on the spot, creating a seamless shopping experience. This model includes structured order flows and API interactions for efficient order processing and return handling.

Figure 1: Pick-at-Store Order Flows
### Forward Flow

Order Placement
Customer places an order in-store through the POS or Store OS. Fynd OMS creates the order with `order_type` set to `PickAtStore`.

Order Confirmation
Use the [POST Order Confirmation](/konnect/channels/erp-wms/api-documentation/orders/post-order-confirmation) API to change order status from `created` to `confirmed`. Items are reserved for fulfillment, preventing further modifications.

Order Status Tracking
Poll the [GET Order by ID](/konnect/channels/erp-wms/api-documentation/orders/get-order-by-id) API for real-time status updates.

Invoice Generation
If Aggregator generates the invoice and updates Fynd OMS using [POST Update Invoice](/konnect/channels/erp-wms/api-documentation/orders/post-update-invoice). Alternatively, Fynd auto-generates the invoice upon order confirmation.

Fetch Customer Invoice and Shipping Label
Aggregator retrieves invoice and shipping label via [Fetch Customer Invoice](/konnect/channels/erp-wms/api-documentation/orders/post-customer-invoice) and [POST Shipping Label](/konnect/channels/erp-wms/api-documentation/orders/post-shipping-label) APIs after polling [GET Order by ID](/konnect/channels/erp-wms/api-documentation/orders/get-order-by-id).

Order Completion
Order status changes to `handed_over_to_customer` once the customer receives their items. Confirm completion by polling the [GET Orders](/konnect/channels/erp-wms/api-documentation/orders/get-orders) API using `DELIVERED` as an orderStatus filter.

### Return Flow

Return Initiation
Customer initiates a return at the store. Store begins the return process in their third-party ERP/Store OS/Fynd OMS.

Quality Control (QC) Check
Store staff performs a QC check to ensure the product meets return eligibility criteria. Return is accepted upon passing QC.

Return Status Update
Update return status in Fynd OMS to `return_accepted` using [POST Return and QC](/konnect/channels/erp-wms/api-documentation/returns/post-update-return-qc) API.

Credit Note Generation
If Aggregator generates the credit note using [POST Credit Note](/konnect/channels/erp-wms/api-documentation/returns/post-credit-note) API. Alternatively, Fynd auto-generates the credit note upon return acceptance.

Fetch Customer Credit Note
Poll the [GET Returns](/konnect/channels/erp-wms/api-documentation/returns/get-returns) API to verify credit note generation.

Return Completion
Return status changes to `return_completed` once the credit note is processed. Confirm return completion by polling the [GET Returns](/konnect/channels/erp-wms/api-documentation/returns/get-returns) API.
