Create a free API sandbox

Create the virtual account

1. 1

   Sign up and verify your email. A paid challenge is not required for the sandbox.

2. 2

   Open Sandbox account from your account switcher, then choose Keys & connections. You can also use the Open API sandbox link below.

3. 3

   Choose Market and Price venue, then select Create free sandbox. Check the resulting Crypto or TradFi account, exchange, active status, and virtual $100,000 starting balance.

Create an isolated key and test

1. 1

   Select Create sandbox key. Configure the account, name, permissions, and optional address restriction; confirm and save the secret once.

2. 2

   Copy the Sandbox API base URL shown for your deployment. On the public site this is https://prop.qats.us/api/sandbox/v1; the purchased-account API uses https://prop.qats.us/api/v1. A dev-site address is only for that dev deployment.

3. 3

   Check that an account-read response identifies the sandbox. Send a small test order and verify its command result, order, fills, and position.

4. 4

   Sandbox keys and purchased-account keys are not interchangeable. Test funds cannot be withdrawn and do not qualify a challenge or earn performance payouts.

Test TradingView separately

1. 1

   In Sandbox → Keys & connections, select TradingView alerts and Create webhook. A regular sandbox API key is not a TradingView webhook setup.

2. 2

   Use the webhook URL and JSON message issued for that sandbox connection in their separate TradingView fields.

3. 3

   After an alert fires, check the sandbox signal log and resulting position or working order. Follow the illustrated TradingView guide for the alert setup.

Reset and reconnect your integration

1. 1

   Stop your test integration before resetting. In Keys & connections, expand Start over with a fresh sandbox and select Review sandbox reset. Choose the market and venue for the new test account, and read the confirmation.

2. 2

   Confirm Reset sandbox only when you are ready to retire the old test account. The reset cancels its orders, clears exposure, and revokes its API keys and TradingView webhooks.

3. 3

   Check the replacement account and virtual starting balance. Create new credentials, update your integration, and test a read before sending commands again.

4. 4

   Purchased accounts are unaffected. Resetting a sandbox is different from paying for an Evaluation reset.
