API Proxy – Creating proxy service in API Manager

MuleSoft provide both API Management and Development platform for APIs. In any Organization there can be legacy web services which are still consumable but are not as advance as today’s service e.g. Security, Threat detection, HTTPS and other feature. API Manager provide you an out of the box feature to create proxy web service on the go and which can sit before the actual web service and in this way a legacy service can be accessed in more advanced way.

It can provide different features which are not there with the legacy web services like API monitoring, applying different OOTB policies and other management tools.

Think Organization have below legacy service which they want to share with their vendors/client

https://gorest.co.in/

will use below GET API for testing

https://gorest.co.in/public-api/users?first_name=john&_format=json&access-token=1KEOnDHy_8dsAYJHmQv9Z9I6Ff1VnjPqb72G

Goto API manager and click Manage API

Select Create new API and select HTTP API as Asset type

Select “Endpoint with Proxy”, Cloudhub and Implementation URL and Click Save

This will create API Manager Configuration and initially it will show API Status Unregistered

Now go to Deployment Configuration and select the mule runtime and proxy application name and click Deploy

Popup will come and show the progress and once complete, click close

API Status is change to Active

We can see the proxy application in runtime manager

Now we will construct the new URL

To construct the URL we should consider the implementation URL also – https://gorest.co.in/public-api

Proxy URL – http://myuser.us-e2.cloudhub.io will be equal to implementation URL

And then we add the rest of the URL

http://myuser.us-e2.cloudhub.io/users?first_name=john&_format=json&access-token=DjHM4_P-r2IWgrwXSH7-OGRurj-xnaC4G1uU

Now we can take the advantage of API Manager Out of the box feature without implementing them in legacy web services
