Hi Phani,
You can check if the corresponding promotion in AdWords Express is paused by going to the AdWords Express user interface and navigating to the corresponding business. You'll then see the list of promotions, and each one will have a status slider at the bottom. For example, here's a screenshot of a promotion that is paused (INACTIVE).

From the AdWords API, you can see the status of a campaign via the
CampaignStatus field of the CAMPAIGN_PERFORMANCE_REPORT. You won't be able to see AdWords Express campaigns in the AdWords user interface, however. You'll have to use the AdWords Express user interface to view AdWords Express objects.
If that doesn't cover your question, please pass along the campaign IDs of the campaigns in question, along with more details of what you've tried so far, and I'll be happy to help.
