Point of sale (POS) APIs
Retail POS APIs help you to easily build extensions or new features to the POS app. For example, if you are extending the Retail POS application to add new features in which to want to get product details, change prices, or add items to a cart. you can consume APIs that will do the work for you. To do this, you need to call the APIs to do the work. The POS API simplifies the extension pattern and provides continuous support to build the extensions.
Extension patterns have been unified across commerce runtime (CRT), POS, and Hardware station (HWS) by following the request/response pattern. All the POS APIs are exposed as request/response like CRT and HWS.
POS APIs are categorized into three different scenarios:
Consume – Consume public APIs in your extension.
Extend – Override public APIs to do some additional logic.
Create – Create new APIs using the exposed POS interface, which can be used across extensions.
Many APIs can be consumed in extensions. For example, if you want to change the price of the item based on an external web service call, you can call PriceOverrideOperationRequest to change the price of the item. Within the consume, the APIs are sub categorized by module like cart, peripherals, store operations, etc.
Note
A list of the all of the APIs is available in Pos.Api.d.ts, which is part of the Retail SDK (...Retail SDK\POS\Extensions\Pos.Api.d.ts). Extensions must consume only the exposed request and response from the POS.Api.d.ts and no modification is allowed to Pos.Api.d.ts. Extensions should not consume or update any POS APIs, properties, methods, or handlers directly from POS commerce or sessions objects.
How to consume APIs in your extension
Use the following steps to consume Retail APIs in your extensions.
Import the API in your extension file.
For example, if you want to consume the save attribute on cart API in your extension, then you need to add the following import statements.
The pattern is import { api name } from "PosApi/Consume/Module name";
import { SaveAttributesOnCartClientRequest, SaveAttributesOnCartClientResponse } from "PosApi/Consume/Cart";Import the client entities and proxy entities if necessary.
import { ClientEntities } from "PosApi/Entities"; import { ProxyEntities } from "PosApi/Entities";Declare the API variable and execute it using the POS runtime, which you can access the runtime by using: this.context.runtime.executeAsync("api name")
executeAsync<TResponse extends Response>(request: Request<TResponse>): Promise<Client.Entities.ICancelableDataResult<TResponse>>;For example, if you want to execute the tender removal, use SaveAttributesOnCartClientRequest api, and refer to the following steps.
let attributeValue: ProxyEntities.AttributeTextValue = new ProxyEntities.AttributeTextValueClass(); attributeValue.Name = PreEndTransactionTrigger.B2B_CART_ATTRIBUTE_NAME; attributeValue.TextValue = "Yes"; let attributeValues: ProxyEntities.AttributeValueBase[] = [attributeValue]; let saveAttributesOnCartRequest: SaveAttributesOnCartClientRequest<SaveAttributesOnCartClientResponse> = new SaveAttributesOnCartClientRequest(attributeValues); result = this.context.runtime.executeAsync(saveAttributesOnCartRequest);
Samples showing how to access APIs
Get Current cart
// Gets the current cart.
let currentCart: ProxyEntities.Cart;
return this.context.runtime.executeAsync<GetCurrentCartClientResponse>(new GetCurrentCartClientRequest())
.then((getCurrentCartClientResponse: ClientEntities.ICancelableDataResult<GetCurrentCartClientResponse>):
Promise<ClientEntities.ICancelableDataResult<GetCustomerClientResponse>> => {
currentCart = getCurrentCartClientResponse.data.result;
Get Current customer added to cart
// Gets the current customer.
let result: Promise<ClientEntities.ICancelableDataResult<GetCustomerClientResponse>>;
if (!ObjectExtensions.isNullOrUndefined(currentCart) && !ObjectExtensions.isNullOrUndefined(currentCart.CustomerId)) {
let getCurrentCustomerClientRequest: GetCustomerClientRequest<GetCustomerClientResponse> =
new GetCustomerClientRequest(currentCart.CustomerId);
result = this.context.runtime.executeAsync<GetCustomerClientResponse>(getCurrentCustomerClientRequest);
} else {
result = Promise.resolve({ canceled: true, data: new GetCustomerClientResponse(null) });
}
Force void transaction
// Force void tarnsaction.
let forceVoidTransactionRequest: VoidTransactionOperationRequest<VoidTransactionOperationResponse> =
new VoidTransactionOperationRequest<VoidTransactionOperationResponse>(false, this.context.logger.getNewCorrelationId());
this.context.runtime.executeAsync(forceVoidTransactionRequest).then((value: ICancelableDataResult<VoidTransactionOperationResponse>) => {
this.currentCart(JSON.stringify(value.data.cart));
}).catch((err: any) => {
this.currentCart(JSON.stringify(err));
});
