Unable to get KVM value when used within a shared flow in PostClientFlow

[anandrudran]

Hi ,

I am unable to read a KVM value from PostClientFlow, the value is always empty, but when i copy it to preflow hooks or anywhere else in the proxy, it is setting the correct value. Are there any restrictions on the KVM usage on PostClientFlow? Apigee OPDK v4.51?

Hi @anandrudran,

Yes there are restrictions, only MessageLogging, ServiceCallout (Apigee X/Hybrid), FlowCallout and ExtensionCallout (Edge/OPDK) policies are allowed. If you are using a FlowCallout, only the allowed policies in the Shared Flow will execute.

• For Edge and OPDK, see Flows and Message Logging usage notes and  Using the ExtensionCallout policy in a PostClientFlow.
• For Apigee X, see Having code execute after the client receives your proxy's response with a PostClientFlow.
