Trigger a holdings update for all accounts under this connection. Updates will be queued asynchronously. ACCOUNT_HOLDINGS_UPDATED webhook will be sent once the sync completes for each account under the connection.
This endpoint will also trigger a transaction sync for the past day if one has not yet occurred.
Because of the cost of refreshing a connection, each call to this endpoint incurs an additional charge. You can find the exact cost for your API key on the Customer Dashboard billing page
Please note this endpoint is disabled for real-time plans (ex: PayGo). Real-time plans do not benefit from this feature since data is refreshed when calls are made
