Hi Nikhil, 

You need to first send an invitation from your Merchant Center account to your AdWords account and then accept the invitation in your AdWords account. You can use the Merchant Center user interface to send this invitation, or use the Content API for Shopping to update the adwordsLinks of your Account. You can then use CustomerService.getServiceLinks() method to get the links and use CustomerService.mutateServiceLinks() method to set the linkStatus from PENDING to ACTIVE to accept the link. You need to set the serviceType and the serviceLinkId in the operand when you accept the invitation. Please see this guide for more details.
