InfoPath Dev

I am using SharePoint online and trying to coonect the REST service using Infopath form , No authentication on the service. below is the Headers we are receiving from service on Postman service URL : http://182.75.221.187:8080/pathLeaveWebservice/path/emp_data/p_id/ankiteshbijalwan content-type →application/xml date →Thu, 15 Nov 2018 10:14:05 GMT server →Apache-Coyote/1.1 transfer-encoding →chunked

 I see from the message you sent me that this is SharePoint Online. Many REST services are blocked in SharePoint Online. You may want to give FormsViewer a try - that's a Qdabra product that replaces InfoPath Forms Services, and has several options for connecting to REST services. Learn more here.
