WSO2 ESB Expose a REST API keeping URI part - rest

Say I have a REST API hosted on a webserver:
someone.com/api/
I want to expose this REST API through a proxy service using WSO2 ESB.
esb.com/api/
It should forward whatever is after esb.com/api/. So if I hit:
esb.com/api/param1/param2
It should hit the real service using:
someone.com/api/param1/param2
How do I pass the URI parts to the real webservice from a proxy service?

Don't try to use Proxy services for REST API. Proxy Services are for the Web Services. Use API s avialable in WSO2 ESB which are similar to proxy services and intended for REST API. This Oxygen Tank article and this sample document will be useful for you.

SOAP and REST on the same endpoint URI

We have a requirement to expose SOAP service along with GET and POST Calls to the REST service on the same endpoint URI. Any inputs will be appreciated.

wso2 is, is there a method to have a reset service?

I have to create a client application that uses OAuth2 and a REST service. I confirmed that the REST service I can achieve it only by WSO2 ESB? WSO2 IS does not provide any REST service without using other platforms carbon?
There are some rest webservices for oauth2, check https://localhost:9443/oauth2/token

IMS as RESTful WebService Consumer

We need to expose IMS as RESTful webservice consumer. I had referred a document "Creating a RESTful Web Service for IMS-Transaction" by Ivy Ho, which talks about exposing IMS as RESTful webservice provider. In that document they selected an OUTBOUND adapter option while creating an J2C bean(Page Num 4), which makes the data to be passed from application to adapter. Is it possible if I opted INBOUND adapter which makes the data to be passed in to the application from the adapter, will it help me to expose IMS as RESTful consumer.
If any proven methods are available, to expose our application as RESTful webservice consumer, kindly share the same ?
Is it possible in the SOAP GATEWAY server to handle REST calls of the client application. So my core application can consume the REST response of client application after the data mapping in the SOAP GATEWAY server.
Kindly share your views and thoughts. Thanks in advance.
The recommended route for your IMS application to consume an external REST service would be through the API Requester function for z/OS Connect EE. The following link provides a step by step guide for doing exactly what you want: https://www.ibm.com/support/knowledgecenter/en/SS4SVW_3.0.0/com.ibm.zosconnect.doc/scenarios/ims_apiReq_intro.html
The reason this would be recommended is it funnels all outbound calls through a single gateway which can be monitored, modified, and updated without affecting your applications.
SOAP Gateway will not be able to handle REST calls. I suggest looking into IMS Mobile Feature pack which is a restful endpoint for IMS.
IMS Mobile Feature Pack Description:
This feature provides a RESTful endpoint for mobile services to access back-end IMS resources through IMS Connect. A data transformation module is included that converts request and response messages between JSON and the native representation of the input and output messages. Tooling support for modeling, creating, testing, and managing services is provided through IMS Enterprise Suite Explorer for Development.

Backend service with SOAP binding required to expose as a RESTful - WSO2 ESB

What I'm trying to do is as follows,
Business use-case : A backend service with SOAP binding required to expose as a RESTful service. Consumers require to get the responses from JSON using the same API.
I have gone through below links but didn't find them useful. Configurations are either not given or not working.

WSO2 API Manager convert SOAP to REST
WSO2 API Manager - can it convert REST requests to SOAP requests on the backend?
I know the step what to be done but what I'm wondering is how that should be done in the ESB. Exact configurations.
Backend service with SOAP binding required to expose as a RESTful - WSO2 ESB?
If you need to expose a SOAP Service and REST (POX or JSON), you can do it using ESB. You can create a API in ESB and does the mapping between JSON or POX to SOAP. There are samples available in the ESB documentation. Please check from here. You do not need a API manager, if you just need to expose some REST API. You can do it using ESB as well and you do not need to use API Manager.
