Terms and definitions

POS (point of sale) - a place where a user executes the payment for goods or services.

Merchant - small amd medium enterprises, supplier of goods and/or services that work with the SWiP service.

Integrator - an employee of POS/merchant/third-party who connects the merchant's POS to the SWiP system and provides further support.

SWiP loyalty - a loyalty program provided by SWiP, which is configured by the merchant.

User - a person who makes purchases and pays through the SWiP app.

Payment scenarios - SWiP supports following payment scenarios:

Scenario 1 - the user pays by the SWiP app after SWiP loyalty calculation. Payments can be made via various methods: from bank cards, from e-wallets, from payment system, from national payment system and other methods.

Scenario 2 - the user makes payment in cash or by bank card at the terminal after SWiP loyalty calculation.

Two-stage payments - a payment operation that requires additional confirmation.

Holding - the user makes the payment and the funds are put on hold on their bank card. While the funds are put on hold, you can debit funds or cancel the payment within the specified timeout (the payment cancellation period can be changed in the settings).

Withdraw - funds on hold are debited after confirmation.

Using the API

POS API - a programming interface for accepting online payments executed by the SWiP service. Using the API, you can execute a payment, cancel a payment, make refunds, get statements with all orders that are made by the SWiP service.

Integration schema

SWIP can be delivered as an external loyalty system, as well as as an external loyalty system with the specified payment method. To learn more about these loyalty systems, see below.

SWiP loyalty calculation and payment inside the SWiP app

During the payment process, SWiP loyalty is calculated, if there is a loyalty program for the user. This scenario includes payment inside SWiP app using the following payment methods: from bank cards, from e-wallets, from payment system, from national payment system and other methods.

HTTP protocol

Step 1. The POS system creates an order.

Step 2. The POS system receives the Order object.

Step 3. The SWiP app requests order detailed information.

Step 4. The User receives the Order object with personalized loyalty at the SWiP app.

Step 5. The User confirms payment at the SWiP app.

Step 6. The SWiP server sends a request for order payment.

Step 7. The SWiP server receives order payment confirmation.

Step 8. The SWiP app receives order payment confirmation from the SWiP server.

Step 9. The POS system sends a request to get the information about the current order status.

Step 10. The POS system receives the paid order with applied loyalty.

Step 11. The POS system sends a request to close the order.

SWiP loyalty calculation without payment inside the SWIP app

During the payment process, SWiP loyalty is calculated, if loyalty is provided to the user. This scenario includes payment by cash or card in bank terminal.

HTTP protocol

Step 1. The POS system creates an order.

Step 2. The POS system receives the Order object.

Step 3. The SWiP app requests order detailed information.

Step 4. The User receives the Order object with personalized loyalty at the SWiP app.

Step 5. The User confirms payment via alternative payment method (by cash or card in bank terminal).

Step 6. The POS system sends a request to get the information about the current order status.

Step 7. The POS system receives unpaid order with applied loyalty.

Step 8. The POS accepts payment by cash or card in bank terminal.

Step 9. The POS system sends a request to close the order.

Integration URL

URL of the integration environment https://capi3.weawer.ru.

Order and session identification

The id and the merchantOrderId fields act as an order identifier.

Field name	Description
`id (UUID)`	The identifier in the SWiP system. The POS must not fill it. The POS creates an order when sending an order object (Order). The Order object returns with the specified ID field. This field is used in GET requests.
`merchantOrderId`	Order ID in the merchant's system.

The sessionCode field acts as a session identifier.

Field name	Description
`sessionCode`	The session identifier (the text value encrypted in the QR code). If the POS system works in a restaurant mode, then the QR code is received from the server's response to the order creation request.

Transport and protocol

The API uses HTTPS as a protocol. Messages are represented in the JSON format.

Authentification

Authentification is implemented by a static token. The token must be sent in the header of HTTP requests.

The header in every API request should include:

Field name	Value example	Description
Authorization	Bearer 8c6b8b64-6815-6084-0a3e-178401251b68	Token from the merchant’s marketing engine.
X-Merchant-ID	ABCD	The value is sent by the SWiP employee after the merchant's onboarding. Four-letter codes are used at the moment. The values can be expanded in the future.
X-Store-ID	Test storeID	The Store ID that the SWiP employee sends after the merchant's onboarding. The value is taken from the merchant's system: either the real identifier of the store or, if it cannot be received from the POS, the value from the SWiP plugin settings.
X-Cash-ID	1231	POS ID in the merchant's system.
Api-Version	3	API version.

Integration scenarios

The POS API supports several payment scenarios. They differ depending on the payment method and store’s settings.

Grocery store, bakery, coffee shop, restaurant, supermarket and many others

Example of implementation:

The user makes an order at the POS system.
The POS creates an order and sends parameters in the API request headers (for more information, see the Authentification chapter):
X-Merchant-ID - the identifier of the merchant;
X-Store-ID - the identifier of the store in the merchant's system;
X-Cash-ID - the POS ID in the merchant's system.
The user confirms the payment.
The POS closes the order and prints the fiscal receipt.

Vending machine

Example of implementation:

The user selects a product on the vending machine.
The vending machine creates an order and sends parameters in the API request headers (for more information, see the Authentification chapter):
X-Merchant-ID - the identifier of the merchant;
X-Store-ID - the identifier of the vending machine;
X-Cash-ID - the modem IMEI or an empty value.
The user confirms the payment and receives the product.

Order object

The Order object (Order) contains all currently relevant information about the order. The object is generated during creation of an order and sent as a response to some requests.

The order object can contain other fields that the POS is not using yet. They should be ignored.

Create an order

To send an order for loyalty calculation and payment execution, you need to create an Order object. It contains all the necessary payment information.
If necessary, you can always send a single product in the Purchases object, for example, a service.

The order can be in the OPEN status for 1,5 minutes for POS systems that operate in the fast food or retail mode. For POS systems operating in restaurant mode, the timeout is 10 hours.

If one of the following methods was used (/close, /reverses или /refund), and there is a need to create the same or lightly modified order, then it has to have a new merchantOrderId, even if for a single product.

Endpoint

POST /orders

Request format

To create an order, you have to send a request with the following parameters:

The values in the Required column are the following:

true - the field is mandatory when interacting with the service
false - the field is not mandatory when interacting with the service

The request body in each API request must include:

Parameter	Type	Description	Required

`merchantOrderId`	string	Order ID in the merchant's system. If the merchant uses the UUID format to identify orders, this value can be used for the order ID in the SWiP system.	true
`merchantOrderNumber`	string	Merchant order number (printed on a receipt usually).	false
`merchantCashierId`	string	Cashier ID. For POS systems, that sets this parameter.	false
`merchantCashier`	string	Cashier name.	true
`saleDate`	date	Sale date (milliseconds since 1970.01.01). The creation date does not have to match the date that will be printed on the receipt.	true

`positionalDiscount`	boolean	Positional discount (influences the `mrp` parameter)	false

Purchases details

Parameter	Type	Description	Required
`id`	string	Product ID. If merchant uses an UUID to identify purchases, it can be used as id. If not, the SWiP server generates the UUID.	false
`name`	string	Description of purchase.	true
`parentId`	string	Parent product ID. If the order contains products with a modifier, than the modifier should have `parentId`.	false
`productId`	string	Product item (product ID) in the merchant’s system.	false

`unit`	Unit	Units (LITERS, KILOGRAMS, PIECES).	false
`price`	double	Price.	true
`amount`	double	Amount (price * quantity).	true
`mrp`*	double	Minimal retail price	false

*Example of calculation using MRP (minimal retail price)
Here, we are recalculating the final discount.

For example, there are two products that cost $100.
product 1 : $100
product 2 : $100 (mrp $90)

if a 20% discount is applied to this purchase, then the final discount will be $30, which accounts to 15%.

As a result, the system will display 15% on the scoreboard.

Note: The mrp parameter can be applied only if positionalDiscount: true

Response format

The response to the request will contain the same order with the filled fields:

id - SWiP orderId,
sessionCode.

If sessionCode was sent empty, then the field with filled in values will return. It should be printed on the guest receipt or shown on the screen (of the POS system) to the user.

If there is a discount on the entire receipt or on one of the products in the receipt, the DISCOUNT field value in the purchase object will be greater than zero if POSITION DISCOUNT = true.

`id`	path	string	Unique order ID in the SWiP system.	True

Response format

The response to the request will contain the Order object with the current status.

Response example

Order status options and how they change

The POS system waits 90 seconds for the payment. If there is no payment during this time, the POS system has to close the order with amount=0.

An order can have the following statuses:

OPEN,
CLOSED.

Payment is determined by the paid field. Let's say that a payment is made for 100 monetary units:

Order creation:
orderStatus=OPEN, totalOriginal=100, total=100, paid=0, unconfirmed=0
Payment:
orderStatus=OPEN, totalOriginal=100, total=100, paid=100, unconfirmed=100
Order closure:
orderStatus=CLOSED, totalOriginal=100, total=100, paid=100, unconfirmed=0

If you close the order with amount=0, the payment will be cancelled:
orderStatus=CLOSED, totalOriginal=100, total=100, paid=0, unconfirmed=0

Close an order

Sends a request to close the order.

Order closing method can be requested only once. In the request body, you must pass the order closing amount. If there is an error in the closing process or there is no order closing amount, the money for the order will be refunded.

If after closing the order (the amount can be == 0, or either > 0) the order is used in the creation request (/orders), do make sure that the NEW merchantOrderId is specified. In case the old merchantOrderId is specified, there will be an error.

Endpoint

POST /orders/{id}/actions/close

Request format

To close the order, you have to send a request with the following parameters:

Parameter	Parameter type	Type	Description	Required
`id`	path	string	Unique order ID in the SWiP system.	True
`amount`	body	double	Order closing amount.	True
`tags`	body	List<String>	If there is a tag, the rounding will be applied.	False

Request example

Response format

The response to the request will contain the Order object with the current status.

Rounding

Sends a request to round the total cost of the purchase.

If earlier there was a zero amount in the total amount of the order, the order was canceled, and the Customer received a refund of the amount paid. Now, if there is an amount for rounding in the total amount of the order, the "ROUNDED" tag is used. It should be noted that this approach only works for alternative payment (cash).

At the same time, the difference between TotalCloseAmount and the ROUNDED tag should not be more than one, since only pennies can be rounded.

Request example
