ASP Form Integration

We have a client portal that needs to have an existing PHP form converted and integrated into an ASP page that captures lead data and post to an internal client portal. The form would be similar to { "TrimExceptions": null, "XDate": "sample string 1", "XDateDescription": "sample string 2", "XDateLineAcordCode": "sample string 3", "XDateLineInternalCode": "sample string 4", "AdditionalActivityNote": "sample string 5", "XDatePeriod": "sample string 6", "CustomerNo": "sample string 7", "ContactSubType": "sample string 8", "FirstName": "sample string 9", "MiddleName": "sample string 10", "LastName": "sample string 11", "Phone": "sample string 12", "Email": "sample string 13", "Line1": "sample string 14", "Line2": "sample string 15", "City": "sample string 16", "State": "sample string 17", "County": "sample string 18", "Zip": "sample string 19", "Country": "sample string 20", "LocationID": 1, "Status": "sample string 21", "ContactType": "sample string 22", "BusinessName": "sample string 23" } The remaining data would be attached. We have been given API Documentation for integration. Form will reside in a Wordpress site.
