Hi,

1. I have create service connection in VBCS.

2. Service connection call OIC's lookup export REST API.

3. On Button click event 'Call REST Endpoint' action event is called to invoke service connection of lookup export REST API.

4. After completion of 'Call REST Endpoint' action event, I am expecting header data in response to somewhat we get it in POSTMAN. But in browser console we observe altogether a different object of header from response of REST API.

PFA doc for 

1. POSTMAN response's header data.

2. Response received in form REST end point in VBCS monitored in browser console.
