A test desk, then production
CircuitCasino does not take players onto this website. The wallet and the lobby remain with you. Opening starts with two details, not with a bill.
What those two details are
The callback URL, and the currencies settled on the account. Keys are issued after that. Nothing is charged at this point.
What the test desk is
The test desk is the project opened before production. It is not billed. There is no setup charge.
What the $500 does
A $500 DepositPay balance moves the project into production. Later bills spend that balance. A first bill of $400 leaves $100. A first bill of $8,000 means the remaining $7,500 is transferred. If the deposit is in and the project never launches, the $500 is returned in full.
When a bill is due
Bills go out on the 1st for the month just closed and are payable within 10 days. After that the API stops until the bill is paid, then access returns on its own. Paying within the first three days avoids the stop.
How long opening takes
Once the callback URL and the currency list are in, most desks are ready inside one business day.
How the callback is used
The callback URL is the address on your side that CircuitCasino calls for each round. It is the only wallet connection. You send that URL and the currencies the account settles. Keys come back after those two details, and the test desk opens with no invoice and no setup charge. The same callback stays in place when the project moves from the test desk to production. A new lobby format does not require a second integration.
What the four studios share
Pragmatic Play, PG Soft, Amatic and Amusnet are prepared from studio source and delivered on this one callback. Amusnet joined the feed on 2 February 2026. A fifth studio is added only when that source is worth preparing. Hold and target return can differ by market and by campaign, including when several brands share one account. Free spins, win replays, streamer accounts and prize drops sit in the API. Bonus Win rounds are left off the bill.
What a first bill does to the deposit
Production starts when a $500 DepositPay balance is in place. That balance is not a second fee on top of the bills. A first bill of $400 leaves $100 on the balance. A first bill of $8,000 means the remaining $7,500 is transferred. If the deposit is placed and the project never launches, the $500 is paid back in full. Bills go out on the 1st for the month just closed and are payable within 10 days. After that the API stops until the bill is settled, then access returns on its own. Paying inside the first three days avoids the stop.
Who answers after the keys
Each account has a project manager and a technical specialist, with developers behind that pair. Test questions and failed live rounds go to them, including overnight. Most desks are ready inside one business day after the callback URL and the currency list arrive. Players are not registered on virtual-circuit.org. The wallet and the lobby stay with the operator.
Common questions
Is the test desk billed?
No. The test desk is free, and there is no setup charge. The $500 deposit is what opens production, and later bills reduce it.
What comes back if the project never launches?
If the deposit is placed and the project does not launch, the $500 is returned in full.
When does an unpaid bill stop the API?
Bills go out on the 1st for the month just closed and are payable within 10 days. After that the API stops until the bill is paid, then access returns on its own. Paying within the first three days avoids the stop.
The four studios are listed on the studio section. Languages, currencies and lobby formats are on the coverage section.
