# What do I do if I want to change the scopes my application requests?

To use Calendar Access modes, you’ll need to be requesting the `free_busy_write` scope when authorizing a user’s calendar via [Individual Connect](/developers/api/authorization/request-authorization/index.md) or for [Enterprise Connect](/developers/api/enterprise-connect/request-authorization/index.md) if your application doesn’t do so already.

If your application is not requesting `free_busy_write` scope, you will need to update the requests you are making when Requesting Authorization with this scope:

#### Individual Connect
**Required Scope**: `free_busy_write`

```
    https://app.cronofy.com/oauth/authorize?response_type=code
      &client_id={CLIENT_ID}
      &redirect_uri={REDIRECT_URI}
      &scope=free_busy_write
      &state={STATE}```
<br>
#### Enterprise Connect
**Required Delegated Scop**: `free_busy_write`

**Required Scope**: `service_account/accounts/manage`

```
    https://app.cronofy.com/enterprise_connect/oauth/authorize
    ?response_type=code
    &client_id={CLIENT_ID}
    &redirect_uri={REDIRECT_URI}
    &scope=service_account/accounts/manage
    &delegated_scope=free_busy_write
    &state={STATE}```
<br>
Once your application begins using the `free_busy_write` scope users will be presented with Calendar Access mode authorisation screens.  They’ll then be able to choose which access mode they’d like to connect their calendars with.
