cheapkeys supplier API

Sell game keys, top-ups and gift cards through one REST API.

Read the public docs, build against a deterministic sandbox, and verify HMAC-signed webhooks. Authenticate with a bearer token, handle RFC 9457 problem+json errors, page with cursors, and retry safely with idempotency keys. Median integration time: under an hour.

Your first sale in 15 minutes API reference

Your first call in 5 minutes

  1. 1 Create a ck_test_ token in the supplier portal (env toggle = Sandbox) in about 30 seconds. Submitting your supplier application approves you into the sandbox instantly, so you can mint a token and call the sandbox base URL right away.
  2. 2 Export it and list the catalog: 
export CK_TEST_TOKEN="ck_test_..."

curl "https://sandbox-pay.mmokick.com/api/v1/products?limit=3" \
  -H "Authorization: Bearer $CK_TEST_TOKEN" \
  -H "Accept: application/json"

Responses carry X-RateLimit-* and X-Request-Id headers, and paginate with next_cursor. Next: the full first-call walkthrough.
