Set up selling items
Selling items
You can sell items in the following ways:
- Fast purchase of one item. In this case, you can sell one SKU in any quantity (for example, 100 identical potions or a custom amount of virtual currency).
- Buying a cart. In this case, the player can pre-fill a cart, add or remove items, or change their quantities.
Fast purchase
- Call the Create order with specified item API. A token for opening the payment UI will be passed to the response.
- Open payment UI using received payment token.
Cart purchase
Implement the logic:- To set up a cart and get the token:
- On the client — if you want to implement the cart in your application by yourself.
- On the server — if you want to use Xsolla’s solution (In-Game Store API calls) to manage the cart.
- To open payment UI.
Set up and purchase a cart on the client
Implement the logic of adding and removing items by yourself. You also need to consider that before calling API for setting up a cart, you will not have information about which promotions will be applied to the purchase. This means that the total cost and details of the added bonus items will not be known.
- After the player has filled a cart, call the Fill cart with items API. The current information about the selected items (prices before and after discounts, bonus items) will be passed to the response.
- Call the Create order with all items from current cart API. The order ID and payment token will be passed to the response. The created order will receive a New order status.
- Open payments UI.
Set up and purchase a cart on server
This variant may take longer for setting the cart up, since each change to the cart must be accompanied by API calls.
Complete the following steps:
- Change the cart:
- For adding an item or changing item quantity, call the Update cart item by card ID API.
- For removing an item, call the Delete cart item by card ID API.
- Call the Create order with all items from the current cart API. The order ID and payment token will be passed to the response. The created order will receive a New order status.
- Open payment UI.
Opening the payment interface
For paying items, open the payment UI. A token for opening the payment UI will be passed to the Create order with all items from current cart API response.
Implement the opening of the payment UI in one of the following ways:
- In a new window. To open the payment UI in a new browser window, use the link:
https://secure.xsolla.com/paystation3/?access_token=ACCESS_TOKEN
, whereACCESS_TOKEN
is the token received when the order was created. - Via widget. Use the Xsolla PayStation Widget script (README file contains instructions).
