Quickstart: Add your first item to a player's inventory

  • Article

Important

Economy v2 is now Generally Available. For support and feedback, go to the PlayFab Forum.

Get familiarized with Player Inventories by using the PlayFab Beta SDK to purchase an item and check that it has been added to your player's inventory. After getting an entity token to interact with your title via the APIs, you search for an item in your catalog, purchase the item, and then get the player's inventory to find the purchased item.

Prerequisites

Sign in as the player

You first need to sign in the player to receive the security token required for the remainder of the API calls in this quickstart. You can find more information on the Player Authentication page.

Search for the item

To find the item in the catalog, you'll need to call Search. In the call body:

{
  "Search": "[Item Title]",
  "Top": 1
}
  • The Search is the search string that will be fuzzy searched against the Title, Description, and Keywords of every item in your catalog
  • Top is an integer that determines how many results to return - in this case we only need one

Note

There are additional fields you can learn about in the Search quickstart.

In the response, grab the following fields:

  • Items > Id - Catalog ID of the item
  • Items > PriceOptions > Prices > Amounts > ItemId - ID of the virtual currency used to purchase the item
  • Items > PriceOptions > Prices > Amounts > Amount - Amount of the virtual currency needed to purchase the item

Note

Only Title Entities are able to set prices for Items

Purchase the item

To purchase the item call PurchaseInventoryItems. In the call body:

{
  "Item": {
    "Id": "{{ItemID}}",
  },
  "Amount": 1,
  "PriceAmounts": [
    {
      "ItemId": "{{CurrencyId}}",
      "Amount": 15
    }
  ]
}
  • The Item.Id is the ID of the item (pulled from the Search response in the previous step)
  • The Amount is the number of items the player is purchasing
  • The ItemId is the ID of the virtual currency used to purchase the item (pulled from the Search response in the previous step)
  • The Amount is the amount of the virtual currency needed to purchase the item (pulled from the Search response in the previous step)

Get the player's inventory items

See the player's newly purchased item via GetInventoryItems. In the call, ensure the body is empty - you can specify the entity in the body, but isn't necessary, as the information is already being passed in through the entity token in the header.

The response contains IDs of each item the player owns and the amount of each item. The newly purchased item will be in the player's inventory.

Note

If the player already has that item in their inventory with the same StackId, you won't see another item instance after the purchase - instead, you'll simply see the Amount field increase.

Troubleshooting

  • Insufficient funds
    • If you call PurchaseInventoryItems and receive a 422: InsufficientFunds error, the player doesn't have enough virtual currency to purchase the item. You can grant virtual currency to the player by calling AddInventoryItems (requires title entity token) or navigating to [Title] > Players > [Player] > Inventory (V2) in Game Manager
  • The item can't be purchased at the specified price
    • If you call PurchaseInventoryItems and receive a 1071 error code, the PriceAmounts field doesn't match the prices specified in the catalog.

Next steps

Now that you purchased the player's first item, you can consume the item, you can add the item to a store to put it on sale, and you can create and purchase a bundle containing the item.
