Defining Multiple Proxy Endpoints

This is probably an unusual case as I'm trying to define a new Proxy Endpoint in an API Proxy.

Let's say I have a default Proxy Endpoint with a Conditional Flow to match /myflow and action == GET and that works fine.

then I defined a new Proxy Endpoint (new_endpoint) with its own Conditional Flow to match /mynewflow and action == GET.

/mynewflow works fine and goes to the new_endpoint as expected.

however

/myflow is also now going to new_endpoint! (i used the Trace tool and confirmed it).

Here is the HTTP Proxy Connection Settings for both:

<HTTPProxyConnection>
    <BasePath>/v2</BasePath>
    <Properties/>
    <VirtualHost>default</VirtualHost>
    <VirtualHost>secure</VirtualHost>
</HTTPProxyConnection>
<RouteRule name="default">
    <TargetEndpoint>default</TargetEndpoint>
</RouteRule>

Is this expected? If it is, how do I make sure that /myflow routes to default Proxy Endpoint?

I learned something today: apparently it's HttpProxyConnection/BasePath dictates which Proxy Endpoint is selected

as soon as made sure that the BasePath is different for both endpoints, routing started the way I expected it to.

Looks like you're missing your <RouteRule> in your proxy. Just like the ConditionalFlow, you need a second RouteRule to point to your new target, which would look something like this:

<HTTPProxyConnection>
    <BasePath>/v2</BasePath>
    <Properties/>
    <VirtualHost>default</VirtualHost>
    <VirtualHost>secure</VirtualHost>
</HTTPProxyConnection>
<RouteRule name="new_endpoint">
    <TargetEndpoint>new_endpoint</TargetEndpoint>
    <Condition>(proxy.pathsuffix MatchesPath "/mynewflow")</Condition>
</RouteRule>
<RouteRule name="default">
    <TargetEndpoint>default</TargetEndpoint>
</RouteRule>

You don't need to include individual verbs, because we can assume everything to /mynewflow is going to go to the new_endpoint target.

Also, make sure you put the conditional RouteRule above the default RouteRule -- Apigee will match the first one so if default (no condition) is first, you will never match the condition on the remaining rules.
