Hi there,

I need to create a Payment Process Request for certain invoices using web services.

When I create a Payment Process Request, into Selection Criteria tab we found Invoice Group field. So I took a invoice and update Invoice Group field and run Payment Process Request for this Invoice Group.

Now, I need to do this but using web services. I found REST API for invoice update but how can I create a Payment Process Request passing Invoice Group value using web service or running a job?
