• I get a notification that our API Usage is at 101%+ usage
• Our Marketo and Workato integrations cease to work

When I check out the API usage by user report in the last 24 hours I see nothing coming close to 100% usage. After stumbling upon this page: https://help.salesforce.com/HTViewSolution?id=000003706&language=en_US which mentions:

"NOTE: This report displays SOAP API usage, but REST API (including Bulk API) calls are not included in the report, which might explain why the data displayed in the report does not match the figure returned by the System Overview page."

I'm lead to believe it's our REST API usage that is causing us to go over our API limit.

Is there any way to find out where these API calls are coming from? If more details are needed, I'd be happy to provide them.

Thanks in advance!
