Methods and Events

You can initiate method calls and listen for events. Method calls initiate requests, some of which return a response. Events are asynchronous system-generated messages that are sent in response to method calls to return the requested data to you.

All of the method calls, except for NotifyFulfillment, request data from the system. When you initiate a request for data, the system immediately returns an object containing a requestId string, which is a unique request identification string. The requested data is returned asynchronously via an event. The NotifyFulfillment method call does not return a response because its purpose is to notify Amazon that your app has delivered the purchased item to the user.

To get the data contained in an event, you must define a handler function and bind it to an event listener for the specific type of event. The returned data, accessible from within your event handler, includes a unique requestId that matches the requestId that was returned in the request method call. You can use the requestId to match a specific request to a specific response, if necessary.

Initiating Method Calls in Adobe AIR

To initiate a method call, you must perform the following general steps:

  1. Import the API package.
  2. If needed, construct the object used to pass input to the operation. There are several ways to construct the input object. See Constructing an Input Object for a complete description.
  3. For asynchronous operations, define a callback function that is invoked when a response is ready.
  4. Call the operation, passing in any required input and/or callback function as arguments.

Constructing an Input Object

You may define an input object in one of several ways:

  • By passing arguments to the constructor.
  • By constructing an empty object and then using implicit setters to set the object's properties.
  • By constructing an empty object and then chaining together with-setter method calls.

The following table describes the various methods that are defined on input objects and show an example of each of the three ways in which you can construct an input object.

NotifyFulfillmentInput

public function NotifyFulfillmentInput(receiptId:String=null, fulfillmentResult:String=null)

Constructor. The constructor optionally takes arguments corresponding to the member variables. If you do not supply any arguments to the constructor, you can set the values of the member variables at a later time either by using the implicit setters, or by chaining together with-setter calls.

public function withReceiptId(receiptId:String):NotifyFulfillmentInput

With-setter. Sets the receipt id of a NotifyFulfillmentInput object and returns the object so that calls can be chained together

public function get receiptId():String

Implicit getter. Allows private variable access through dot notation. Returns the string value representing the receipt id.

public function set receiptId(receiptId:String):void

Implicit setter. Allows private variable access through dot notation. Sets the string value representing the receipt id.

public function withFulfillmentResult(fulfillmentResult:String):NotifyFulfillmentInput

With-setter. Sets the fulfillment result of a NotifyFulfillmentInput object and returns the object so that calls can be chained together.

public function get fulfillmentResult():String

Implicit getter. Allows private variable access through dot notation. Returns the string value representing the fulfillment result.

public function set fulfillmentResult(fulfillmentResult:String):void

Implicit setter. Allows private variable access through dot notation. Sets the string value representing the fulfillment result.

Sample code

 / Constructor example
notifyFulfillmentInput:NotifyFulfillmentInput = new NotifyFulfillmentInput("12345", "FULFILLED");

// Implicit setters example
notifyFulfillmentInput:NotifyFulfillmentInput = new NotifyFulfillmentInput();
notifyFulfillmentInput.receiptId = "12345";
notifyFulfillmentInput.fulfillmentResult = "FULFILLED";

// With-setters example
notifyFulfillmentInput:NotifyFulfillmentInput =
    new NotifyFulfillmentInput().withReceiptId("12345").withFulfillmentResult("FULFILLED");

ResetInput

public function ResetInput(reset:Boolean=false)

Constructor. The constructor optionally takes arguments corresponding to the member variables. If you do not supply any arguments to the constructor, you can set the values of the member variables at a later time either by using the implicit setters, or by chaining together with-setter calls.

public function withReset(reset:Boolean):ResetInput

With-setter. Sets the reset of a ResetInput object and returns the object so that calls can be chained together

public function get reset():Boolean

Implicit getter. Allows private variable access through dot notation. Returns the boolean value representing whether to get a list of all purchases.

public function set reset(reset:Boolean):void

Implicit setter. Allows private variable access through dot notation. Sets the boolean value that determines whether to get a list of all purchases.

Sample code

 // Constructor example
resetInput:ResetInput = new ResetInput(true);

// Implicit setter example
resetInput:ResetInput = new ResetInput();
resetInput.reset = true;

// With-setter example
resetInput:ResetInput = new ResetInput().withReset(true);

SkuInput

public function SkuInput(sku:String=null)

Constructor. The constructor optionally takes arguments corresponding to the member variables. If you do not supply any arguments to the constructor, you can set the values of the member variables at a later time either by using the implicit setters, or by chaining together with-setter calls.

public function withSku(sku:String):SkuInput

With-setter. Sets the SKU of a SkuInput object and returns the object so that calls can be chained together.

public function get sku():String

Implicit getter. Allows private variable access through dot notation. Returns the string value of the SKU.

public function set sku(sku:String):void

Implicit setter. Allows private variable access through dot notation. Sets the string value of the SKU.

Sample code

 // Constructor example
skuInput:SkuInput = new SkuInput("SKU_20156789");

// Implicit setter example
skuInput:SkuInput = new SkuInput();
skuInput.sku = "SKU_201387654";

// With-setter example
skuInput:SkuInput = new SkuInput().withSku("SKU_201954321");

SkusInput

public function SkusInput(skus:Vector.<String>=null)

Constructor. The constructor optionally takes arguments corresponding to the member variables. If you do not supply any arguments to the constructor, you can set the values of the member variables at a later time either by using the implicit setters, or by chaining together with-setter calls.

public function withSkus(skus:Vector.<String>):SkusInput

With-setter. Sets the SKUs of a SkusInput object and returns the object so that calls can be chained together.

public function get skus():Vector.<String>

Implicit getter. Allows private variable access through dot notation. Returns the string vector that holds the SKUs.

public function set skus(skus:Vector.<String>):void

Implicit setter. Allows private variable access through dot notation. Sets the string vector that holds the SKUs

Sample code

 // Helper object
skus:Vector.<String> = new Vector.<String>();
skus.push("SKU_012345", "SKU_246810", "SKU_135792", "SKU_987654");

// Constructor example
skusInput:SkusInput = new SkusInput(skus);

// Implicit setter example
skusInput:SkusInput = new SkusInput();
skusInput.skus = skus;

// With-setter example
skusInput:SkusInput = new SkuInput().withSkus(skus);

GetUserData

GetUserData initiates a request to retrieve the user ID and marketplace of the currently logged-in user.

// Import the API package
import com.amazon.device.iap.cpt.*;

// Call the synchronous GetUserData operation, which does not take input
var requestOutput:RequestOutput = AmazonIapV2.getUserData();

    var response:GetPurchaseUpdatesResponse = event.getPurchaseUpdatesResponse;
    var requestId:String = response.requestId;
    var userId:String = response.amazonUserData.userId;
    var marketplace:String = response.amazonUserData.marketplace;
    var receipts:Vector.<PurchaseReceipt> = response.receipts;
    var status:String = response.status;
    var hasMore:Boolean = response.hasMore;

    // for each receipt you can get the following values
    var receipt:PurchaseReceipt = receipts[0];
    var receiptId:String = receipt.receiptId;
    var cancelDate:Number = receipt.cancelDate;
    var purchaseDate:Number = receipt.purchaseDate;
    var sku:String = receipt.sku;
