# Update screen

PUT /screens/{screen}. Parameters, permissions, request and response schemas.

`PUT /screens/{screen}`

Update screen. Requires the REST `write` token ability. The bearer token selects the Team; a supplied team\_id cannot switch tenants. Additional role, entity-policy and plan requirements vary by operation. A Team in blocked billing mode cannot write and receives 402.

## Authentication

Use a team API key as `Authorization: Bearer YOUR_API_KEY`. The token ability and the user’s role must both allow this operation. See [authentication](https://conversionlab.app/docs/developer/authentication).

```json
{
  "ability": "write",
  "team": "Token-bound Team",
  "authorization": "Additional role, entity-policy and plan requirements vary by operation.",
  "billing": "Blocked billing mode rejects writes with 402."
}
```

## Parameters

| Name     | Location | Required | Description   |
| -------- | -------- | -------- | ------------- |
| `screen` | path     | Yes      | The screen ID |
