Create Evaluation Accounts

### Batch create up to 100 simulation accounts at once. **Available to:** Organization administrators **Environments:** Demo **[Rate Limit](/overview/core-concepts/rate-limits):** 100 requests per hour, 1-second back-off, counts failed requests only This endpoint can help greatly reduce your application's API usage footprint. It batches the functionality of several calls at once for each EvaluationAccount configuration object: - The `userId` field controls which user will be assigned a Trading Permission for this account once it is created. - Providing a `preTradeRisk` will allow you to apply `userAccountPositionLimit` and `userAccountRiskParameter` settings directly. - Providing a `postTradeRisk` will allow you to set the `userAccountAutoLiq` settings directly. The `name` field for each account must use uppercase letters (A-Z) followed by one or more digits (0-9), with a maximum length of 64 characters. No lowercase letters, spaces, special characters, or underscores are allowed, and letters must come before digits. Valid examples: `TESTACCOUNT123`, `SIMACCOUNT001`. Invalid examples: `abc123`, `ABC_123`, `A1B2C3`. If the `name` value doesn't match the required format, the API returns `HTTP 400` with a `violations` array: ```json { "violations": [ { "constraint": "name", "value": "my_account_1", "description": "Account name should follow the next regexp: ([A-Z])+\\d+" } ] } ``` Use this endpoint when creating new accounts to minimize API traffic. ***Note***: This endpoint replaces [/user/openDemoAccount](/api/rest-api-endpoints/users/open-demo-account) and [/user/createTradingPermission](/api/rest-api-endpoints/users/create-trading-permission).
