We also have a CLI that ships with prefect so you can kick off flow runs without python

Richard Hughes · Answer

< Dylan> is this the one I should use ```prefect client client Client create flow run ``` What if I don t know the flow id and only the flow name I need to query the flow id

Dylan · Answer

< Richard Hughes> You can also pass a `version group id` instead of an `id` The version group persists across all versions of your flow and will always run the latest

Dylan · Answer

That way you only need to know that id once

Dylan · Answer

I believe this is set to the `flow group id` by default

Dylan · Answer

Which you can find in Flow Details tile in the UI

Dylan · Answer

If not you can set the `version group id` to whatever string you d like at registration time Just pass `version group id` to `flow register `

Richard Hughes · Answer

Dylan · Answer

That correct You can use the flow s name if you d like
