A Zap is a blueprint for tasks you may have to do over and over again: “When I get a new thing in A (a trigger), do this other thing in B (an action). SmartSurvey can be both a trigger and an action, and you can mix and match them to automate just about anything.
An example might be – A new lead created in Salesforce could trigger a survey to be automatically sent to them – You can create as much granularity as you need. For instance, you might say that the phone number from your SmartSurvey contact form should be the work phone of your new Salesforce lead. Say you receive five new entries, Zapier takes each one and makes a new lead in Salesforce, customized to the way you specified in your Zap.
Without any more effort from you, data flows from one service to the other!
