Consume external REST/SOAP service

Hi,

We are working on a SAP UI5 application which will consume external REST/SOAP services via SAP Gateway. The reason we are using gateway is to hide the basic authentication logic.

My questions are:

1] Can we consume REST service in Gateway which can later be consumed in SAP UI5 app via url? I know we can write a ABAP code to consume REST but does Gateway has any such feature to skip the ABAP coding?

2] Similarly, how can we consume SOAP Service and create OData service?

Thanks
