# Open Demo Account

POST https://demo.tradovateapi.com/v1/user/opendemoaccount
Content-Type: application/json

### Request to open a Demo account for a user.

***Note***: The `/user/createEvaluationAccounts` endpoint replaces [/user/openDemoAccount](/api/rest-api-endpoints/users/open-demo-account) and [/user/createTradingPermission](/api/rest-api-endpoints/users/create-trading-permission).

Typically used by B2B Partners to open simulation accounts for their users.
- The `defaultAutoLiq` field controls the auto-liquidation paramters for the account. Setting it here will save an API call to `userAccountAutoLiq/update`, and should be preferred. It also prevents issues related to incorrect SOD balance when called during market close.
- The `preTradeRisk` field allows you to wrap `userAccountPositionLimit/create` and `userAccountRiskParameter/create` calls into the account creation operation. This can save many API calls if you have complicated pre-trade risk settings to apply for your users.
