Remix Shop Items

Manage Shop Items Workflow

Overview

This skill guides you through creating, managing, and integrating shop items for games on the Remix platform.

Prerequisites

• A game must be created on the Remix platform (you need a game ID).
• The REMIX_API_KEY environment variable must be set.

Steps

1. Check for Existing Game ID

Read .remix-settings.json in the current directory. If it exists and contains a gameId, use that value.

Only if .remix-settings.json does not exist or has no gameId should you follow the upload-game workflow to create one.

2. Manage Shop Items

List All Items

GET https://api.remix.gg/v1/games/{gameId}/items
Authorization: Bearer $REMIX_API_KEY

Create an Item

POST https://api.remix.gg/v1/games/{gameId}/items
Authorization: Bearer $REMIX_API_KEY
Content-Type: application/json

{
  "name": "Speed Boost",
  "description": "Doubles player speed for 30 seconds",
  "price": 100,
  "type": "consumable",
  "imageUrl": "https://asset-url.png",
  "metadata": { "duration": 30 }
}

• type can be "consumable" (can be purchased multiple times) or "permanent" (one-time purchase)
• imageUrl and metadata are optional

Update an Item

POST https://api.remix.gg/v1/games/{gameId}/items/{itemId}
Authorization: Bearer $REMIX_API_KEY
Content-Type: application/json

{ "price": 150 }

Accepts a partial body -- only include fields you want to change.

Delete an Item

DELETE https://api.remix.gg/v1/games/{gameId}/items/{itemId}
Authorization: Bearer $REMIX_API_KEY

3. Integrate Shop Items in Game Code

Add the RemixSDK shop integration to your game:

const sdk = window.RemixSDK

// Check if player has a permanent item
const hasItem = sdk.hasItem('item-id')

// Get purchase count for a consumable item
const count = sdk.getItemPurchaseCount('item-id')

// Trigger the purchase flow (opens platform purchase UI)
sdk.singlePlayer.actions.purchase({ item: { id: 'item-id' } })

// Listen for purchase completion
sdk.onPurchaseComplete(({ item }) => {
  // Grant the item in-game
})

Wrong Patterns

Do NOT do any of the following:

• Granting items without listening to onPurchaseComplete. Always wait for the callback before giving the player anything. The purchase may fail or be cancelled.

• Using localStorage to track purchases. The platform handles purchase state. Use hasItem() and getItemPurchaseCount() to check ownership.

• Hardcoding prices in game code. Always read prices from the API. If you change a price on the server, hardcoded values in the game will be wrong.

Tips

• Use "consumable" for items players buy repeatedly (lives, boosts, ammo).
• Use "permanent" for one-time unlocks (characters, levels, cosmetics).
• Always check hasItem() on game load to restore permanent purchases.
