# Method name: updateSyncConfig(connectionId: string, syncConfig: ConnectionSyncConfig, options: UpdateSyncConfigOptions)

# Method package: wixBookingsV2

# Method menu location: wixBookingsV2 --> externalCalendars --> updateSyncConfig

# Method Link: https://dev.wix.com/docs/velo/apis/wix-bookings-v2/external-calendars/update-sync-config.md

# Method Description:

Updates the specified external calendar connection's sync configuration.


Use Update Sync Config to update a connection's `syncConfig` property.
The `syncConfig` property contains settings for enabling, configuring, or disabling functionality, including:

+ Importing events from one or more specified calendars in the connected external calendar account. If this is enabled, use `listEvents()` to retrieve a list of events from the external calendar.
+ Exporting events from the Wix site's calendar to an external calendar.

To see an external calendar connection's existing sync configuration, use `getConnection()` or `listConnections()` and see the `syncConfig` property.

> **Note:**
> Supported functionality depends on the provider. Use `listProviders()` to see details about providers' supported features.



# Method Code Examples:

*** Note: do not assume any prop names or enum values other than the ones in the example.

## Update connection to list events from specific external account calendars  

```javascript
import {externalCalendars} from 'wix-bookings.v2';

async function updateSyncConfig(connectionId) {
    const syncConfig = {
        listEventFromCalendars: {
            enabled: true,
            calendars: {
                calendars: [
                    {
                        id: 'a68yu6lp6584z66zorp19z1ab'
                    },
                    {
                        id: '4xve0tohyhnrlzy3lp4zf7b07'
                    }
                ]
            }
        }
    }
    const {connection: updatedConnection} =
        await externalCalendars.updateSyncConfig(connectionId, syncConfig)
    return updatedConnection
}
```

## Update connection to sync events to a new dedicated external account calendar  

```javascript
import {externalCalendars} from 'wix-bookings.v2';

async function updateSyncConfig(connectionId) {
    const syncConfig = {
        syncToCalendar: {
            enabled: true,
            dedicatedCalendar: {}
        }
    }
    const {connection: updatedConnection} =
        await externalCalendars.updateSyncConfig(connectionId, syncConfig)
    return updatedConnection
}
```
