Only supported in Sandbox. Settles a single payment, which moves from processing to paid. Works on the employer debit and on employee and contractor credits.

The payment must have a status of processing. Right after [Sandbox] Start processing, a payroll's payments are draft for a few seconds, so wait until they're processing before calling this endpoint. Find a payroll's payments with List payments.

We recommend setting the payroll's simulation_mode to manual, so the payroll doesn't advance on its own while you test. See Testing Payments in Sandbox.
