Designing the Process
Inter-process communication
Process Builder includes an Invoke Process activity template that enables a parent process to invoke a
child process. An example of this is if you have an order process that must perform a credit check.
Instead of building the credit check procedure into the order process, create it as a separate process to
be invoked as a child process. You can manage the credit check process separately and independently,
and it can be called by other parent processes.
The Invoke Process activity template provides a basic mechanism to pass process data from the parent
process to the child process. By using the Post Event to Parent activity template, the child process
communicates to the parent process by posting events to the parent process instance. However, the
posted event is only a name that carries no payload to the parent. To pass a data payload from the
child to the parent, use the following approach:
In this example, the parent process invokes the child process in the third activity:
