<Update label="1.0.0" description="2 February 2026" tags={["Initial release"]}>
  ## Initial version

  First public release of the Zero-Dash integration documentation.

  **Customer API** — endpoints you call on Zero-Dash:

  * [List games](/api-reference/customer/list-games)
  * [Obtain game launch URL](/api-reference/customer/game-launch-url)
  * [Create free rounds campaign](/api-reference/customer/create-campaign)
  * [Create free rounds bonus code](/api-reference/customer/create-bonus-code)
  * [Search free rounds campaigns](/api-reference/customer/search-campaigns)

  **Wallet callbacks** — endpoints you implement:

  * [Player authorization](/api-reference/callbacks/player)
  * [Debit](/api-reference/callbacks/debit)
  * [Credit](/api-reference/callbacks/credit)
  * [Rollback](/api-reference/callbacks/rollback)
  * [Get transaction](/api-reference/callbacks/get-transaction)

  **Shared conventions:**

  * HMAC-SHA512 [request signature](/security/signature) over `apiPath|timestamp|data`, in both directions
  * ISO-8601 UTC timestamps in bodies, Unix milliseconds in `X-Zd-Timestamp`
  * ISO-4217 currencies, decimal amounts on the wire, 8-decimal cap on crypto
  * Mandatory [idempotency](/wallet/idempotency) on all transaction endpoints
  * Durable retries for credit and rollback over a 3-day window
