How to Extract SOAP Action from request headers?

What is the request.header parameter to be used to extract soap header from incoming request?

Tried request.header.SOAPAction but no luck.

Please suggest.

Using Javascript is could extract the request header - 'SOAPAction' successfully. The key is to check if extract function matches header name (case sensitive)

@vinay poreddy How are you trying to extract it?

var soapAction = context.getVariable('request.header.SOAPAction');

Above JS works.Thanks for the information.

Question:

Have you tried using extract variable and assign?

[vikaas_shivalin]

Yes,

Here is a sample for Extract Policy,

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ExtractVariables async="false" continueOnError="false" enabled="true" name="Extract-Variables-1">
    <DisplayName>Extract Variables 1</DisplayName>
    <Properties/>
    <Header name="SOAPAction">
      <Pattern ignoreCase="false">{SOAPHeaderValue}</Pattern>
  	</Header>    
    <IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>    
    <Source clearPayload="false">request</Source>
    <VariablePrefix>apigee</VariablePrefix>    
</ExtractVariables>

Now you can access the SOAP Header value using {VariablePrefix}.{Pattern}. i.e apigee.SOAPHeaderValue

If you are using JS,

var soapAction = context.getVariable('apigee.SOAPHeaderValue');

Sample Assign Message Policy to copy value from apigee.SOAPHeaderValue to another variable - flow.soap.header

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<AssignMessage async="false" continueOnError="false" enabled="true" name="Assign-Message-1">
    <DisplayName>Assign Message 1</DisplayName>
    <Properties/>     
	<AssignVariable>
    		<Name>flow.soap.header</Name>
    		<Ref>apigee.SOAPHeader</Ref>
    		<Value>NULL</Value>
	</AssignVariable>
    <IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
    <AssignTo createNew="false" transport="http" type="request"/>
</AssignMessage>

Hope this helps!!
