Hey Stephan,
It is not (yet) possible to add a pageload to a workflow, as far as I know.
As an alternative, you can add a workflow step “check_sales_channel” of the type “user interaction” with a “continue” button that shows a message like: “Sales channel with id XX has been created. Double check that all data is correct and press continue”.
It is also possible to retrieve all relevant data from the sales channel and put it in the message so that the user does not have to navigate to the sales channel:
"Sales channel with ID XX has been created. Double check that all data is correct and press continue:
Property 1: ABC
Property 2: CDE
… "
You can configure the messages in the workflow transition to the step “check_sales_channel”.
