# Error handling

Toggle returns descriptive messages for any returned errors (as opposed to error codes or numbers).

For this reason, we recommend that you shouldn't try to re-interpret error strings to your own UI, and instead use them verbatim.

Here's an example error response:

```javascript
{
  "errors": [
    {
      "message": "validation",
      "locations": [
        {
          "line": 2,
          "column": 29
        }
      ],
      "validation": {
        "currency": [
          "This field is required"
        ]
      },
      "customer_facing": false
    }
  ],
  "data": {
    "createBalanceAdjustment": null
  }
}
```
