The property filter adds the possibility to select the properties for GET operations.

Syntax: ?properties[]=<property>&properties[<relation>][]=<property>

You can add as many properties as you need. The following example shows how to select paymentType and
issuer.rfc when fetching a list of invoices.

  curl -i https://api.syntage.com/taxpayers/{id}/invoice?properties[]=paymentType&properties[issuer]=rfc
