# List experiment approvals

GET /experiments/{experiment}/approvals. Parameters, permissions, request and response schemas.

`GET /experiments/{experiment}/approvals`

List experiment approvals. Requires the REST `read` 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.

## 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": "read",
  "team": "Token-bound Team",
  "authorization": "Additional role, entity-policy and plan requirements vary by operation."
}
```

## Parameters

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