# Validates and updates the editable grid code fields provided in the request body. Fields omitted from the request are left unchanged.

`PUT /grid-code`

## Request

- Base URL: `http://integrations.api.prod.zaptec.com`
- URL: `http://integrations.api.prod.zaptec.com/grid-code`
- Auth: HTTP bearer

Updates editable grid code parameters and settings for the charger identified by **`evseId`**.

This is a partial update: included fields are changed, omitted or `null` fields stay unchanged.

Rules:

- `evseId` must use format `NOZAPE<serial>`, for example `NOZAPEZPR000090`.

- At least one editable field must be provided.

- GET `metadata` contains all known fields; fields with `editable: false` are read-only for PUT.

- Unknown, read-only, out-of-range, and invalid-step fields return `400`.

- Do not PUT a full GET response back unchanged; remove read-only fields first.

### Example request

```json
{
  "fuse_limit": 32,
  "dso_max_export_limit": 16,
  "grid_code_settings": {
    "v_min_normal": 0.85,
    "f_min_normal": 49.0,
    "threshold_over_frequency": 50.2
  }
}
```

### Validation examples

Valid examples:

- `f_min_normal: 49.0`

- `max_under_frequency: 49.8`

- `under_frequency2_time: 0.1`

- `restore_time_after_fault_rt: 60`

Invalid examples:

- `max_under_frequency: 49.85` - because the step is `0.1`

- `under_frequency2_time: 0.05` - because the minimum is `0.1`

- `under_frequency2_time: 5.1` - because the maximum is `5.0`

- `restore_time_after_fault_rt: 60.5` - because it is an integer field

- `f_max_normal` - because it is returned by GET but is read-only for PUT

### Error response example

```json
{
  "type": "https://tools.ietf.org/html/rfc9110#section-15.5.1",
  "title": "One or more validation errors occurred.",
  "status": 400,
  "errors": {
    "grid_code_settings.max_under_frequency": [
      "Field must use a step of 0.1."
    ]
  }
}
```
