How do see full request/response body in the Trace UI?

Be default, Apigee will not display the full request/response payload within the Trace UI as it can be quite large at times. However, if you wish to see the full payload for either of these, you can do so by adding an AssignMessage policy within the respective request/response flow that assigns the request.content or response.content variable to another variable. Here’s an example.

<AssignMessage async="false" continueOnError="false" enabled="true" name="GetFullRequestPayload">
    <DisplayName>GetFullRequestPayload</DisplayName>
    <FaultRules/>
    <Properties/>
    <AssignVariable>
        <Name>reqpayload</Name>
        <Value/>
        <Ref>request.content</Ref>
    </AssignVariable>
    <IgnoreUnresolvedVariables>true</IgnoreUnresolvedVariables>
    <AssignTo createNew="false" transport="http" type="request"/>
</AssignMessage>

Once the request.content or response.content variables are accessed, the full variable value will be displayed in Trace.

Hi Dave,

Can you expand on what you mean by “Once the request.content or response.content variables are accessed”? Do you mean by adding another policy, such as AssignMessage, that references "reqpayload’?

Hi Stephen,

Yes. By accessed, I mean using another policy, e.g. AssignMessage, JavaScript, etc. that makes reference to the request.content or response.content variable depending upon the payload one would like to see.

Thanks Dave, exactly what I needed, I just use this AssignMessage throughout my flow with enabled true or false to grab debug information as needed.
