The Inventory API lets you access most of the same information as the Roblox My Inventory page. You can check whether a user owns individual items and retrieve the full list of items that a player owns.
Responses from the Inventory API include items from the following categories:
- Clothing (accessories, bottoms, classic clothing, shoes, tops)
- Purchases and rewards (badges, passes, purchased places, private servers)
- Avatar items (avatar animations, classic heads, emotes, faces, hair, heads)
Before using the Inventory API, you must generate an API key or configure OAuth 2 for your app. The examples on this page use API keys.
Checking Item Ownership
If you want to check whether a user owns a particular item (for example, a limited, badge, pass, or private server), use the filter parameter to check for a comma-separated list of one or more IDs. This code sample checks for three asset IDs:
const https = require('node:https');
const userId = 11111111111;
const hostname = 'apis.roblox.com';
const path = `/cloud/v2/users/${userId}/inventory-items`;
const params = '?filter=assetIds=62724852,1028595,4773588762';
const url = 'https://' + hostname + path + params;
const apiKey = '123456789012345678901234567890123456789012345678';
const options = {
headers: {
'x-api-key': `${apiKey}`,
},
};
https
.get(url, options, (response) => {
console.log('statusCode:', response.statusCode);
let data = '';
response.on('data', (d) => {
data += d;
});
response.on('end', () => {
if (response.statusCode === 200) {
const jsonData = JSON.parse(data);
console.log('Response Data:', JSON.stringify(jsonData, null, 2));
} else {
console.error('Error:', response.statusCode, response.statusMessage);
}
});
})
.on('error', (e) => {
console.error(e);
});
The following response indicates that the user owns one of the three items:
{
"inventoryItems": [
{
"path": "users/11111111111/inventory-items/VVNFUl9BU1NFVF9JRD0yMDAxMDUxMTkzODg",
"assetDetails": {
"assetId": "1028595",
"inventoryItemAssetType": "CLASSIC_TSHIRT",
"instanceId": "200105119388"
}
}
],
"nextPageToken": ""
}
Filtering Items
If you want to display, for example, only the collectibles that a user owns, use the same code as above, just with a different filter parameter.
const params = '?filter=onlyCollectibles=true;inventoryItemAssetTypes=*';
Mix and match filters using a semicolon-separated list. Here are a few examples:
filter=onlyCollectibles=true;inventoryItemAssetTypes=HAT,CLASSIC_PANTSfilter=badgeIds=111111,222222;gamePassIds=777777;privateServerIds=999999filter=gamePasses=true;badges=true
Most calls to the API do not require any specific permissions, but several filters require Inventory read permissions. For more information, see Filtering.
Paginating Results
If a response includes a value for nextPageToken, use that value in the pageToken parameter of the subsequent request to retrieve the next page. For more information, see Pagination.
If the number of results is divisible by maxPageSize (for example, you have 50 results and a maxPageSize of 25), you can encounter a situation in which your response includes a value for nextPageToken, but a request using that token returns no results:
GET /cloud/v2/users/{userId}/inventory-items?maxPageSize=25&pageToken=cccDDD
{
"inventoryItems": [],
"nextPageToken": ""
}
When implementing pagination in your app, best practice is to check not just for a non-empty nextPageToken, but also for a non-empty inventoryItems array.
