Hello! I would like to ask how you can get the value of a declared path parameter and pass it to the invoke URL in Gateway Policy.

For example, I created a GET operation with a path

/users/{user}

wherein {user} is the declared parameter located in the path. Is it possible that when the APIC endpoint is invoked it will get the value of {user} from that endpoint and pass it on to the URL such that it will be invoked in our microservice as

$(host-url)/users/{user}

Appreciate any help you can extend!

Hi Michael,

If your API is invoked with /users/steve for example, request.parameters.user would have a value of steve.   A shorthand for request.parameters.user  is {user} so in your invoke policy

$(host-url)/users/{user}

or 

$(host-url)/users/$(request.parameters.user)

would have a target url of something like https://hostname:port/users/steve
Best Regards,
Steve
