Endpoint URL
This topics describes the format of the Nintex Forms Web Service API endpoint URL.
All of the resources and methods provided by the REST API for both Nintex Forms 2010 and Nintex Forms 2013 use the following root path as the endpoint URL, replacing {Site} with the SharePoint site collection or site URL:
{Site}/_vti_bin/NintexFormsServices/NfRestService.svc
For example, the following URL represents a request to delete a form from a SharePoint list on the site implemented for Crestan:
https://crestan.com/_vti_bin/NintexFormsServices/NfRestService.svc/DeleteForm
