Hi, how can I kick off an agentless flow run on cloud backend via python API? The equivalent of

prefect run --execute

. I was going to do

ShellTask("prefect run --execute").run()

but thought there might be another way. Maybe

create_flow_run

It’s quite complicated but you can try the execute_flow_run_in_subprocess function here. Your method might be easier to get running

How do I get

prefect.cli.run.run

de-decorated? And what is the the difference between

create_flow_run

execute_flow_run_in_subprocess

and

prefect.cli.run.run(execute=True)

prefect.cli.run.run.callback

provides access to the undecorated function

Running a flow with the API takes two steps • Create a flow run in the backend (gives you an id) • Execute the flow run (takes an id)

create_flow_run

is a task that does the first step then relies on an agent to perform execution

prefect run --execute

does both steps. It creates a flow run with a label that no agent has (so the agents do not execute it) then executes the flow in a subprocess.
