@Kevin Kho @Anna Geller I’ve created a new api key for one of our service accounts using the

Create API Key

option in prefect cloud’s

Service Account

page. When I use that for flow registration I get this warning:

/opt/hostedtoolcache/Python/3.9.7/x64/lib/python3.9/site-packages/prefect/client/client.py:175: UserWarning: Client was created with an API token configured for authentication. API tokens are deprecated, please use API keys instead.

I set the auth token/key in a python file like this:

client = prefect.Client(
        api_token='secret value'
    )
client.save_api_token()

The docs only seem to show how to set

auth_api_key

when using the prefect cli or a graphql query. Does this mean using the api you’re still using the deprecated token? (I’ve peeked into prefect’s implementation for the

Client

class and everything still says

api_token

, but that might be a red herring!)

Use

api_key

instead of

api_token

in the Client. Key is now preferred going forward. A bit more info in the docstring here

@Kevin Kho thank you, makes sense!! (I think we’re still using older Prefect versions in some of our projects which might be why I couldn’t find

api_key

!)
