Fetching Products

Before fetching products from Appmate, ensure that you created products by following Creating Products page.

Fetching Products from Appmate

This page describes how to fetch the products. With the getProducts method of PurchaseClient, you will get the active products synced with the Google Play Store and Huawei App Gallery.

If you have created some products for your app for the first time, it may take time to get synced products, as Google has a time delay in activating the products. Synchronization of product prices with Google may take some time.

After you called getProducts method, the products will be cached in the sdk for 10 minutes. So you will be able to get the response faster than getting directly from the network. If you add a new product and want to see it in your app for testing purposes, you can delete your app's cache. The products will be fetched from the network the next time you open your app. getProducts method returns products in the form of List<Product>. If you failed to fetch products and getting a GenericError , note the following:

You can access the list of all products, list of some spesific products or the list of products filtered by product types.

To handle the result of the asynchronous operation, you must specify a listener which implements the ReceivedDataListener interface. You can then override onSucceeded(), which notifies the listener when the query finishes successfully or with failure, as shown in the following code:

1. Fetching all products:

Request

Parameter Name	Type
listener	ReceivedDataListener<List<Product>, GenericError>

Response

Parameter Name	Type
onSucceeded	List<Product>
onFailed	GenericError

Kotlin

PurchaseClient.getInstance().getProducts(    new ReceivedDataListener<List<Product>, GenericError>() {          @Override          public void onSucceeded(List<Product> data) {          }          @Override          public void onError(GenericError error) {          }    });

Java

PurchaseClient.instance.getProducts(    object : ReceivedDataListener<List<Product>, GenericError> {        override fun onSucceeded(data: List<Product>) {        }
        override fun onError(error: GenericError) {        }    })

2. Fetching products by specifying a list of some productIds:

When calling getProductsByProductIdList(), pass a productIdList that specifies a list of product ID strings created in the Creating Products page of our web console.

Request

Parameter Name	Type
productIdList	List<String>
listener	ReceivedDataListener<List<Product>, GenericError>

Response

Parameter Name	Type
onSucceeded	List<Product>
onFailed	GenericError

Kotlin

PurchaseClient.getInstance().getProductsByProductIdList(productIdList,    new ReceivedDataListener<List<Product>, GenericError>() {       @Override       public void onSucceeded(List<Product> data) {       }       @Override       public void onError(GenericError error) {       }    });

Java

PurchaseClient.instance.getProductsByProductIdList(productIdList,     object : ReceivedDataListener<List<Product>, GenericError> {        override fun onSucceeded(data: List<Product>) {        }
        override fun onError(error: GenericError) {        }    })

3. Fetching products filtered by product types:

Request

Parameter Name	Type
productType	ProductType
listener	ReceivedDataListener<List<Product>, GenericError>

Response

Parameter Name	Type
onSucceeded	List<Product>
onFailed	GenericError

Kotlin

PurchaseClient.getInstance().getProductsByProductType(productType,    new ReceivedDataListener<List<Product>, GenericError>() {       @Override       public void onSucceeded(List<Product> data) {       }       @Override       public void onError(GenericError error) {       }    });

Java

PurchaseClient.instance.getProductsByProductType(productType,     object : ReceivedDataListener<List<Product>, GenericError> {        override fun onSucceeded(data: List<Product>) {        }
        override fun onError(error: GenericError) {        }    })
