Play Cards API

A simple HTTP API to check your balance, browse products, place orders, and track their status — built for resellers and automation.

Base URL https://api.play-cards.net

Drop-in compatible Idempotent orders Webhooks Stable error codes

Introduction #

The API speaks JSON over HTTPS. If you already integrate with a standard reseller API in this market, you migrate by changing only the base URL and your token — the paths, envelopes, and error codes match.

✓

All endpoints are GET requests and return JSON. Send your token on every request. Orders are idempotent via order_uuid.

Authentication #

Every request must include your API token in the api-token header. You can generate and manage your token, allowed IPs, and callback URL from your account.

HEADER

api-token: YOUR_API_TOKEN

Two additional header forms are accepted for convenience: x-api-key: YOUR_API_TOKEN and Authorization: Bearer YOUR_API_TOKEN.

⚠

IP allowlist. If your account has an IP list configured, requests from any other IP are rejected with code 123. Leave the list empty (or enable “allow all IPs”) to accept requests from anywhere.

Rate limits #

API requests are rate-limited per token. Stay under the limits below and you will never see an HTTP 429.

Scope	Limit	When exceeded
newOrder	120 requests per minute per token	HTTP `429`
products (catalog sync: plain or `price=1`)	1 request per minute per token — the full catalog in one response; syncing every 1–2 minutes is the intended pace	HTTP `429` with a `Retry-After` header (seconds)
products with `base=1` (product-linking list)	6 requests per minute, up to 60 per hour per token — sized for a human linking products, not for automated polling	HTTP `429` with a `Retry-After` header (seconds)
other endpoints	1200 requests per minute per token (content, check, profile)	HTTP `429`
checkId	60 lookups per minute per token by default; cached repeats are free	HTTP `429` · code `135`

These are counted per token, not per IP, so spreading requests across servers does not raise the limit. On HTTP 429, pause and retry after a few seconds — the response message includes how long to wait.

✓

Syncing prices or stock? Fetch the whole catalog in one call with /client/api/products?price=1 — it returns a lightweight payload for every product. Do not call the API once per product: a large catalog synced product-by-product burns through the read limit for no benefit.

Webhooks #

Instead of polling /check, set a callback URL on your account and we’ll POST to it whenever one of your orders reaches a final state. This is optional and complements the polling endpoint.

POSThttps://your-server.com/your-callback

Headers we send

  }
}

🔒

Respond with HTTP 2xx to acknowledge. Any other status is retried. To verify authenticity, look the order up with /client/api/check?orders=[publicId] before acting on it.

Errors #

Every error returns the same envelope with a stable numeric code. Build your integration against the code, not the message text.
