Go-live checklist

What we check before issuing production credentials.

GET /v1/ping answers your operator code, and server_time is within seconds of your clock.
GET /v1/games pages through to the end and every game opens from launch_url.
Your wallet verifies our signature: a call with a wrong signature is refused with a 4xx.
Your wallet answers getbalance with a string balance.
A bet debits; the same bet again answers the same body and debits nothing.
A bet beyond the balance answers 4xx INSUFFICIENT_FUNDS and the balance is untouched.
A win credits, including "0.00", and a win for a refused bet is credited.
A rollback returns the bet; a rollback for an unseen id answers the current balance, and that bet sent afterwards is refused.
Wins and rollbacks on a closed session are credited.
Your wallet answers within your timeout, well under a second in normal operation.
You can find any of our transaction ids through GET /v1/transactions/{id} in your own books.

From sandbox to production

You start in the sandbox. Our onboarding mail brings an invitation to the sandbox Operator Portal and a one-time link to your signing secret. The link shows the secret once; we never send a secret by email or chat. A link that expired or was opened by someone else is replaced by a new one on request.
The Operator Portal's Overview counts what is left: the wallet test suite passed against your current wallet URL, a game played with money settled in your wallet, and the addresses your servers call from set under Credentials.
When all three pass, press Request production access and give your production wallet URL (HTTPS) and the addresses your production servers call from.
We review the request and promote you. Production sends its own onboarding mail: an invitation to the production Operator Portal and a one-time link to your production secret.

Store the production secret from its link, then switch the base URL and the key pair. Nothing else in your code changes.
Admit the addresses we call your wallet from, listed in the production portal.
The games you are entitled to in production are set by your account manager and appear in the production portal's Games.
