Is there a way to know why my API limit is increasing quickly?

Hello:  Received an email yesterday that our API limit was reached.  If there a way to find out what is causing the limit to be reached?  We are integrating with Zapier - are they requesting information from the API too often?  Any help is greatly appreciated.  Thanks, Ashley

Yes you are using this limit only with the Zapier integration, you can also check this in your account by clicking on this link https://jotform.com/myaccount/api. 

This integration with Zapier has used API calls for 9935 times, I would suggest you to check the forms you have integrated with Zapier and if you do not use some of these forms then remove the integration, otherwise you will have calls from this API.
