Following is a sample proxy service and fault handler sequence you can use as a starting point for handling faults when integrating with SurveyMonkey. Customize this sample to match your requirements.

Sample Proxy
<proxy xmlns="http://ws.apache.org/ns/synapse" name="SurveyMonkey_sampleProxy" transports="https,http" statistics="disable" trace="disable" startOnLoad="true">
  <target>
    <inSequence onError="faultHandlerSeq">
