The web form settings include an option to auto import new web form data into an automatically generated lead:

If the option is disabled, then the system does not create a new lead upon the form submittions. Instead, the submitted data goes into a queue on the Manage Incoming Data page.

Administrators can then review the queue of received leads and decide whether or not to complete the lead creation process.

By not importing new leads into the CRM automatically, clients can review for possible spam or fraud before bringing a lead in.

You can open the Manage Incoming Data page from the administration page (Web Forms > Manage Incoming Data):

The page shows two tabs including the Incoming Data and the Incoming Leads tabs.

The Incoming Data tab shows the new web form submissions that were not auto-imported and are awaiting review and approval to create the lead record.

Selected leads can be imported to the CRM using the Import Selected Leads button:

The Incoming Leads tab shows a historical record of new leads that were created by web form submission.

Use the View Data button to view the information imported with the submission:
