how to use the REST API for POST method in SAP gateway

Hi ,

My requirement is to get  the data from Salesforce to SAP..

Sales force will  POST the closed work order data & same data , I need to post it back to SAP using ODATA.

I have created ODATA service for POST method.

How the REST API can use this ODATA service( for POST) ?

I have no idea on REST API.

Please let me know regarding this.

Thanks,
