Parameters

request: A Leadtools.Services.Cloud.DataContracts.AddJobsRequest class for the jobs to add.

Return Value

A Leadtools.Services.Cloud.DataContracts.AddJobsResponse class containing information for the added jobs.

Use this method to add a batch of jobd to the cloud database with a single call to the server WCF service. The Leadtools.Services.Cloud.DataContracts.AddJobsResponse class will contain the ID's (Guid's) of the added jobs. To add a single job, use AddJob.
