# Change Demo Balance

POST https://live.tradovateapi.com/v1/cashBalance/changedemobalance
Content-Type: application/json

### Change the cash balance of a demo account.

Available to: All authenticated users

Environments: Demo

**[Rate Limit](/overview/core-concepts/rate-limits) (organization administrators):** None

**[Rate Limit](/overview/core-concepts/rate-limits) (all other users):** One balance change per account per hour, with a max account balance of $50,000

Quickly adjust the simulated cash balance of a demo account in your organization. Use this endpoint to reset a trader's balance during an evaluation, top up an account before a new challenge phase, or adjust a balance after a practice session when you don't need the additional control that `adjustCash` provides.

<Warning>**Warning:** This endpoint returns **HTTP 200** for successes **and** business errors. Always check the `errorText` field in the response body to determine whether the request succeeded or failed.</Warning>

**Difference Between `changeDemoBalance` and `adjustCash`**

The `changeDemoBalance` endpoint is available to all traders and has rate limits to protect against abuse. Because `adjustCash` is restricted to organization administrators with `Funds` permissions, it supports higher throughput and doesn't have a rate limit. `adjustCash` also gives you more control: you can classify the adjustment type, specify the currency, and include an audit comment.

**Field Details**

The `accountId` must reference an active demo account within your organization. You can look up account IDs using the Query Builder in the Admin Dashboards or via the `/account/list` endpoint.

The `cashChange` value is applied as a change to the current balance (positive values increase the balance and negative values decrease it). The `cashChange` value must be between -1,000,000 and 1,000,000 (exclusive). The resulting balance cannot exceed $50,000.

If the optional `comment` field is omitted, the server defaults to "Demo Change".

**Reversing a Change**

While you can't undo a change, you can make another `changeDemoBalance` call with the opposite `cashChange` amount.

**Common Failure Scenarios**

- Account ID is invalid (must be greater than 0)
- Balance change requested within one hour of the last change
- Balance change would cause the total account balance to exceed $50,000
- `cashChange` is outside the allowed range (must be between -1,000,000 and 1,000,000, exclusive)
- `comment` exceeds 64 characters
- Demo account is closed or inactive
- Request sent to the live or replay environment

**Error Messages**

| `errorText` | Trigger |
|-------------|---------|
| `"Access denied"` | Called on a non-demo environment (secondary guard) |
| `"Account Id should be greater than 0"` | `accountId` is 0 or negative |
| `"Cash Change should be greater than -1000000"` | `cashChange` is -1,000,000 or less |
| `"Cash Change should be less than 1000000"` | `cashChange` is 1,000,000 or greater |
| `"Comment should be no longer than 64"` | `comment` exceeds 64 characters |
| `"Demo account is closed"` | The account is inactive |
| `"Maximum cash amount in the simulation account must be less than or equal to $50,000"` | Resulting balance would exceed $50,000 |
| `"One change to the simulation cash balance is permitted per hour. Please try again later."` | Called within one hour of the last change |
| `"This endpoint should be called on demo.tradovateapi.com"` | Called on the live or replay environment |
