Once you have an instance of the IDeliveryClient, you can start querying your environment by calling methods on the instance.
// Retrieves a single content item
IDeliveryItemResponse response = await client.GetItemAsync<About>("about_us");
// Retrieves a list of all content items
IDeliveryItemListingResponse listingResponse = await client.GetItemsAsync<About>();
The SDK supports full scale of the API querying and filtering capabilities as described in the Delivery API reference.
// Retrieves a list of the specified elements from the first 10 content items of
// the 'brewer' content type, ordered by the 'product_name' element value
IDeliveryItemListingResponse<Brewer> response = await client.GetItemsAsync<Brewer>(
new ElementsParameter("image", "price", "product_status", "processing"),
new LimitParameter(10),
new OrderParameter("elements.product_name")
);
The language selection is just a matter of specifying the LanguageParameter parameter with a codename of the required language.
// Retrieves a list of the specified elements from the first 10 content items of
// the 'brewer' content type, ordered by the 'product_name' element value
IDeliveryItemListingResponse<Brewer> response = await client.GetItemsAsync<Brewer>(
new LanguageParameter("es-ES"),
new ElementsParameter("image", "price", "product_status", "processing"),
new LimitParameter(10),
new OrderParameter("elements.product_name")
);
To display a paging navigation you need to retrieve the total number of items matching the search criteria. This can be achieved by adding the IncludeTotalCountParameter to the request parameters. With this parameter, the item listing responses will contain the total number of items in the Pagination.TotalCount property. This behavior can also be enabled globally by calling the IDeliveryOptionsBuilder.IncludeTotalCount method. Please note that response times might increase slightly.
// Retrieves the second page of items including a total number of items matching the search criteria
IDeliveryItemListingResponse<Brewer> response = await client.GetItemsAsync<Brewer>(
new LanguageParameter("es-ES"),
new OrderParameter("elements.product_name"),
new SkipParameter(5),
new LimitParameter(5),
new IncludeTotalCountParameter(),
