Reserves a Employer's place in a Web Occurrence. 

A Employer Web Reservation is created which links the Web Employer to the Occurrence. 

A reservation is a type of web enrolment. The Employer Web Reservation can be retrieved, updated, deleted, and have employees added to it, like a normal employer web enrolment, except that it is not yet available for processing by a VETtrak user. To "complete" the reservation and turn it into a normal employer web enrolment and make it available for processing in VETtrak, use the CompleteWebReservation function. Using a web reservation also allows the user to configure individual occurrences to automatically process web reservations made into them, which will occur when CompleteWebReservation is called. 

A Web Occurrence ID (iOccu_ID) is passed as a parameter. To be valid, a Web Occurrence ID must :

• be a published Occurrence,
• have at least one vacancy,

Details of the Web Employer (sName and sIdentifier) are supplied as parameters. sIdentifier is the VETtrak Employer Identifier which may or may not be known. Anything entered in this parameter is used by a VETtrak administrator to attempt to match this Employer with existing VETtrak Employers. The parameter, sName, must be non-empty. 

This function is used to create a web reservation by a company or an employer. Employees are added to this reservation using AddWebEmployee. 

If a person is to be enrolled as an individual client reservation, don't use this function. Instead, use AddClientWebReservation . 

Web reservations added by this function can be viewed in the Reservations tab under the occurrence in the Process Web Enrolments manager in VETtrak. The user can delete them if they so choose. 

A token is passed for authentication. If the authentication fails, or other errors occur, no web enrolment is created. The result of the authentication is represented by a TAuthenticate object. 

Requires a valid registration key entry for the Bookings feature. 

This function has security level "Protected", and can only be accessed by users that have explicitly been granted permission to the API.
