Steamworks-dokumentation > Reference for Steamworks-web-API > IInventoryService grænseflade

Dette er grænsefladen, som bruges til at tilgå Steam-inventartjenesten.

BEMÆRK: Dette er en tjenestegrænseflade. Metoder i denne grænseflade bør kaldes med parameteren input_json.

Se Web-API-oversigt for flere oplysninger om, hvordan du bruger Steamworks-web-API'en.

AddItem

POST https://partner.steam-api.com/IInventoryService/AddItem/v1/

Name	Type	Required	Description
key	string	✔	Steamworks Web API publisher authentication key.
appid	uint32	✔	The ID of the application associated with the item.
itemdefid	uint64	✔	List of the itemdefid's to grant. Dette bør angives som en serie af parametre navngivet "itemdefid[0]", "itemdefid[1]" osv.
itempropsjson	string	✔
steamid	uint64	✔	SteamID of the player to receive the items.
notify	bool	✔	Optional, default 0. Set to 1 to indicate the user is not in-game and should see a Steam notification.
requestid	uint64	✔	Optional, default 0. Clients may provide a unique identifier for a request to perform at most once execution. When a requestid is resubmitted, it will not cause the work to be performed again; the response message will be the current state of items affected by the original successful execution.
trade_restriction	bool	✔	Optional, default 0. Set to 1 to have Steam apply market and trade cooldowns as if this was a purchased item.

AddItem is used to add new items directly in a user's inventory. For each itemdef, an instance of that type is created and added to the target account.

Items of type 'bundle' or 'generator' are unpacked at the time they are added. The response message provides information about the item or items that were actually inserted in the inventory.

This call will fail if the itemdef is not defined or cannot be unpacked; or if the target player does not have permission for the given appid.

Player notification of a new item, if any, is best handled by the game client. Calls to AddItem that occur when the player is not in-game may optionally set notify=1 to notify the player via Steam. This may engage any of the player-notification mechanisms in Steam, including an overlay popup.

The optional requestid parameter allows a client to make an idempotent call. If the client is unsure whether a request completed successfully on the server, it can replay the request, reusing the original request ID.
If the request is replayed, the response will include current state for the items that were affected by the original request, without making new changes.

If the original request fails on the server, replaying the same request ID will re-attempt the work rather than reporting the prior error result.

If the user owns your app from a free license and has not played in the last 30 days, AddItem will also fail.

Svar:

response
- success – true, hvis metoden lykkedes. Hvis asset serveren returnerer false, bør den angive error til en string, som forklarer hvorfor.
- error – en streng, som beskriver, hvorfor dette kald mislykkedes. Denne besked vil blive optaget i en fejllog, som er tilgængelig under fanen "Økonomi" på Steamworks-siden.
- item_json - an array of the item details of the newly created items. This is returned as encoded JSON containing the actual item properties.
- replayed – hvis true, indikerer det, at det givne anmodnings-ID blev behandlet tidligere, og at svaret er baseret på den første eksekvering. This will not be included if requestid is not specified.

Eksempel på svar:

{ "response": { "item_json": "[{ \"accountid\":\"148618792083651397\",\"itemid\":\"17209346500926339\",\"Timestamp\":\"\",\"originalitemid\":\"17209346500926339\",\"itemdefid\":\"120\",\"appid\":480,\"position\":0,\"quantity\":1,\"transid\":\"\",\"state\":\"\",\"origin\":\"external\",\"price\":\"\",\"acquired\":\"20140912T195537Z\"}]" } }

POST https://partner.steam-api.com/IInventoryService/AddPromoItem/v1/

Name	Type	Required	Description
key	string	✔	Steamworks Web API publisher authentication key.
appid	uint32	✔
itemdefid	uint64
steamid	uint64	✔
notify	bool		Skal give brugeren besked om, at genstanden blev tilføjet til deres Steam-inventar.
requestid	uint64	Clients may provide a unique identifier for a request to perform at most once execution. When a requestid is resubmitted, it will not cause the work to be performed again; the response message will be the current state of items affected by the original successful execution.

Tilføjer en promogenstand til brugerens inventar. Hvis den kaldes uden itemdefid-parameteren, tjekker den for og tildeler tilgængelige promogenstande til spilleren.

NOTE: Dette kald kræver en API-udgivernøgle for at bruge denne metode. Derfor SKAL denne API kaldes fra en sikker server og må aldrig bruges direkte af klienter!

ConsumeItem

POST https://partner.steam-api.com/IInventoryService/ConsumeItem/v1/

Name	Type	Required	Description
key	string	✔	Steamworks Web API publisher authentication key.
appid	uint32	✔
itemid	uint64	✔	Genstands-ID, som skal forbruges
quantity	string	✔	Mængden af givne stablede genstande, som skal forbruges
steamid	uint64	✔
requestid	uint64	✔	Clients may provide a unique identifier for a request to perform at most once execution. When a requestid is resubmitted, it will not cause the work to be performed again; the response message will be the current state of items affected by the original successful execution.

Marks an item as wholly or partially consumed. This action cannot be reversed.

NOTE: Dette kald kræver en API-udgivernøgle for at bruge denne metode. Denne API SKAL kaldes fra en sikker server og må aldrig bruges direkte af klienter!

A client SDK version of this call is also available: ISteamInventory::ConsumeItem

ExchangeItem

POST https://partner.steam-api.com/IInventoryService/ExchangeItem/v1/

Name	Type	Required	Description
key	string	✔	Steamworks Web API publisher authentication key.
appid	uint32	✔	The ID of the application associated with the item.
steamid	uint64	✔	SteamID of the player that owns the items.
materialsitemid	uint64	✔	The unique ID an item in the player's inventory to be converted to the target item type. This should be provided as `materialsitemid[0]`, `materialsitemid[1]`, etc.
materialsquantity	uint32	✔	The quantity of the matching item that should be used in this recipe. This array must be the same length as `materialsitemid`.
outputitemdefid	uint64	✔	The ItemDef of the item to be created.

ExchangeItem is used for crafting - converting items using a predefined recipe. A successful exchange destroys the set of items required by the crafting recipe, and adds a new instance of the target itemdef to the player's inventory.

The target item definition must have one or more crafting recipes declared in the exchange attribute. Recipes declare the number and type of items required to create the target item. If the set of items provided in the ExchangeItems call does not satisfy any recipe, the call fails and no changes are made to the inventory.

See the Inventory Service Schema documentation for more detail on crafting recipes.

The crafting operation will take trade and market restrictions into account; the created item will have the latest trade restriction of any item used to create it.

If successful, this call returns an encoded JSON blob that lists the items that were changed by this call - the consumed items and the newly created one.

NOTE: Never distribute your Steam API key with your game. Denne API skal kaldes fra en sikker server og må aldrig bruges direkte af klienter.
