# Account Updater Scopes - V1

[OAuth 2.0 scopes](https://oauth.net/2/scope/) allow you to specify the level of API access required. Since API credentials are limited per vault, API scopes are limited only for that vault as well. Once an access token is granted via the [authentication flow](/cmp/platform/authentication.md), scopes can be located in the issued JWT.

[CALM API credentials](/cmp/developer-resources/api/credential-management-v1-apis-calm.md) can have the following scopes:

| Scope                  | Permission                                     |
| ---------------------- | ---------------------------------------------- |
| `cards:write`          | Enroll and manage a card in CALM               |
| `cards:read`           | Read details about the enrolled card           |
| `network-tokens:write` | Enroll and manage a network tokens in CALM     |
| `network-tokens:read`  | Read details about the enrolled network tokens |
