Note:

There are dependent fields that become queryable based the value from the source field. For example, if you query against po-method=email, then po-email can be added as an additional query criteria. Please see fields with Yes*.
For large data set and for performance optimization, you should always limit your result with some GET criteria.
PO changes do not always increment the version number. See Fields that Cause a Purchase Order Revision for more info. The updated-at field can always be used to determine whether any changes have been made.
In order to see invoice-total returned in the API query, you need to set the default_purchase_orders_filter to default. After updating the default PO API filter, invoice-total shows in the API GET call.
