Policy Composition Mashup
This sample "mashes up" two web services:
- The Google Geocoding web service
- The Google Elevation web service
It exposes an API that takes two query parameters:
- country: A two-letter country code
- postalcode: A postal code valid in that country
It returns a JSON result that includes the geocoded location for the center of that postal code, and the elevation at that location.
It uses a series of policies in order to accomplish this:
- An AssignMessage policy to generate the request for the geocoding web service
- A ServiceCallout policy to call it
- An ExtractVariables policy to parse the response and extract the latitude and longitude
- An AssignMesage policy to set the parameters for the elevation service
- An ExtractVariables policy to parse the elevation response
- A StatisticsCollector policy to send the values of "country" and "postalcode" to Analytics for use in a custom report.
- The username and password that you use to login to enterprise.apigee.com.
- The name of the organization in which you have an account. Login to enterprise.apigee.com and check account settings.
