Postman

Use Postman to try public Inventory requests before adding them to your application. Create your Project, Service Account and Credential in the Dashboard. Default project is a valid starting point; copy the Credential secret when it is shown.

Import the public API

1. Open the API Reference and choose Download OpenAPI Document.
2. Import the downloaded file into Postman as a collection.
3. Confirm that the request server is https://api.steamcall.com.
4. Configure API-key authentication with the header name X-API-Key and your Credential secret as its value. Do not use Bearer authentication.

Keep the secret local and out of shared or exported collections. If a request has its own authentication setting, check that it uses the same API-key header before sending it.

Try an Inventory request

Start with List supported inventory scopes to see which game and context pairs are available. For TF2, use app_id=440, context_id=2, and a public inventory's steam_id.

• To fetch one page directly from Steam, use Load a Steam user's inventory.
• To read a previously completed inventory, use Read a committed inventory revision. If no revision exists, follow Refresh inventory first.
• For a complete new observation, submit Refresh, poll its status, then read Current. Reuse the same Idempotency-Key only when retrying the same Refresh request.

Requests can consume credits. Check Usage & credits before running a collection repeatedly. Review your balance and attributed usage in the Dashboard.

Inspect the result

Check the HTTP status and X-Request-ID, then compare the body with the operation's API Reference. For another page, use the continuation value documented for that operation; V1 compatibility pagination differs from V2. See Pagination.

Remove secrets and personal inventory data from saved examples before sharing them. For an application integration, continue with the Python or TypeScript examples.
