We've been migrating a flow from v1 to v2 and that's all working out fine. However, in v1 we would invoke a flow from Python using code a little like this -

from prefect.client.client import Client

c = Client(api_token='xxxxxxxxxx')
params = {'param1': 'Foo', 'param2': 'Bar'}
c.create_flow_run(
  version_group_id='xxxx-xxxxxx-xxxxxx-xxxxx', 
  run_name='my_run_name',
  parameters = params)

But I can't see a good example of how to do the same with v2! I think I'm missing something fundamental! Thanks

For v2 you use

run_deployment

Ahh. thanks. This is probably the logical leap I needed!

You can login with

prefect cloud login

— the variables needed for authentication in other contexts can then be viewed with

prefect config view

(the API URL and API KEY are the relevant ones). You don’t need to provide a client manually to

run_deployment

it’ll read settings from the environment.

Oh right - so if I have the API URL and API KEY as environment variables in my (in this case) AWS lambda function, the run_deployment will pick up on those?

Exactly. Wonderful :)
