Details how to use shared flows for establishing a common error handling routine for all proxies.

Shared Flow

1. Zip the "sharedflowbundle" folder
2. Upload as a Shared Flow (APIs-->Shared Flows)
3. Deploy to environment needed
4. Customize to add additional error codes, error handling, logging, etc

Example Proxy

1. Zip the "apiproxy"
2. Upload the proxy
3. Deploy to environment needed

Test

1. Import "errorhandlingexample-sharedflow-proxy-v1.postman_collection.json" into Postman
2. Run calls to see response

Proxy Template With Shared Flow Reference

1. This is the proxy template (referenced here: https://github.com/davidmehi/edge-proxy-template) that now uses the shared flow for common error handling.

To use the Shared Flow in a proxy:

1. Add the shared flow "SharedFlow_FaultRulesHanding" using the Shared Flow policy to the proxy.
2. Add the policy to the <FaultRules> and the <DefaultFaultRule> in the default.xml of the proxy. In both cases, the shared flow will be called, which contains the common error handling logic.

    <FaultRules>
        <FaultRule name="Shared Fault Rules">
            <Step>
                <Name>FlowCalloutFaultRulesHandling</Name>
            </Step>
        </FaultRule>
        <!-- could put additional fault rules here if needed -->
    </FaultRules>
    <DefaultFaultRule name="all">
        <AlwaysEnforce>true</AlwaysEnforce>
        <Step>
            <Name>FlowCalloutFaultRulesHandling</Name>
        </Step>
    </DefaultFaultRule>
