Is FileMaker Cloud supported?
There are no issues when using a FileMaker Cloud hosted version of fmAccounting Link (Xero Edition) when using the FileMaker Pro client application as all communication with the Xero API is handled by FileMaker Pro.
FileMaker Cloud does not support server installed plug-ins so you will not be able to perform or schedule any server side scripts or use Perform Script on Server with v1 of fmAccounting Link (Xero Edition).
