write an async function for authenticating with an api-key to prefect server

hi @Larry Profx - there is no auth implemented for oss prefect server, api keys are for authenticating with prefect cloud

then I meant for prefect cloud

you should only have to

export PREFECT_API_KEY

and

PREFECT_API_URL

wherever you're trying interact with your workspace

yes but we don't use workspace and only use the default profile. they don't show up in the UI atleast

I'm afraid there seems to have been a slip-up; the code example I retrieved isn't about authenticating with an API key to Prefect Cloud but is instead for a basic Prefect flow. Let me try searching the documentation to find the proper information regarding authentication with an API key for you. Please wait a moment. To authenticate with an API key to Prefect Cloud, please follow these steps: 1. Creating An API Key: - Go to the Prefect Cloud UI and select the account icon at the bottom-left corner. - Select "API Keys" which displays a list of previously generated keys. - Click the "+" button to create a new API key, provide a name for the key and set an expiration date. - Copy the key as it cannot be revealed in the UI after you generate it. 2. Using the API Key: - Run

prefect cloud login

from your CLI. - Choose to authenticate by pasting the API key when prompted. Note: Ensure that you keep your API key secure and do not share it unnecessarily. For more details and instructions, you can visit the Manage Prefect Cloud API Keys documentation. Here's how you would create an async function to authenticate with an API key:

python
import httpx
from prefect import get_client

async def authenticate_with_api_key(api_key: str):
    # Assuming you have the API key, you can either set it in your client config
    # or use it directly when making requests. Prefect Cloud expects
    # the API key as a bearer token in the Authorization header.
    headers = {
        'Authorization': f'Bearer {api_key}'
    }
    
    # Use httpx AsyncClient or any other async HTTP client to make your requests
    async with httpx.AsyncClient(headers=headers) as client:
        # Example request to authenticate and retrieve your Prefect account details
        response = await client.get('<https://api.prefect.io/graphql>')
        
        # Handle your response
        if response.status_code == 200:
            print("Authenticated successfully.")
            return response.json()
        else:
            print("Failed to authenticate.")
            return None

# Ensure you replace 'YOUR_API_KEY' with your actual API key
api_key = 'YOUR_API_KEY'
client = get_client()
client.set_api_key(api_key)  # This sets the API key for your Prefect Client instance

# Now you can use 'client' within your flows and tasks.

Please replace

YOUR_API_KEY

with your actual API key. This function uses the

httpx

library to make asynchronous HTTP requests, and sets the API key in the headers for authentication. The example shown is a basic example for setting up an async function; depending on the Prefect Cloud API you're interacting with, you may need to adjust the endpoint and parameters accordingly.

i generally wouldnt advise authenticating programmatically - can you clarify what you mean by this / what you're trying to do? > yes but we don't use workspace and only use the default profile. they don't show up in the UI atleast

I can show you on a video call if you're available to help

hi larry, I'd recommend reaching our to our support here to schedule a call otherwise, feel free to describe your goal here and I can help async when available

Need to configure our jenkins pipeline to pass apikey to auth to prefect UI for flow deployment in prefect2.x.x

are you using the sdk/cli to create the deployment? or the rest api directly

Currently we use prefect.yaml and prefect cli command (prefect deploy) for the deployment

makes sense. so you should only ever have to set the two env vars i mentioned earlier.

PREFECT_API_URL

corresponds to a specific workspace, which you must have if you're using cloud, and

API_KEY

corresponds to an actor authenticated in that workspace (which could be a user or a service account) here's an example thats for GHA, but it should be roughly the same for jenkins • set the env vars • use the CLI as you wish to create the deployment

That's what I was saying earlier, we don't have workspaces, we just created an apikey's for different users and automation But if there's a way to set the apikey in the yaml file, that'll be nice Cause I tried the cli command "prefect cloud login - k '<apikey>' " and it isn't working

we don't have workspaces

you do have a workspace if you're using prefect cloud. you may only have a personal workspace, but that is still a workspace. your

PREFECT_API_URL

will look something like this

PREFECT_API_URL='<https://api.prefect.cloud/api/accounts/xxx/workspaces/xxx>'

if

prefect cloud login -k <>

isnt working then there may be a problem with your key or you may be using a version of prefect with a bug in that CLI command

Our PREFECT_API_URL is not in the usual format Ours is just https://prefect2-server.${ENV}.innovation.io/api Prefect2 server version is 2.14.20 If there's a way to pass the api_url and apikey through the prefect.yaml, that would be great

If there's a way to pass the api_url and apikey through the prefect.yaml, that would be great

there is not,

prefect.yaml

is for defining deployments

Ours is just https://prefect2-server.${ENV}.innovation.io/api

are you sure you use prefect cloud? it seems like you're hosting open source prefect here

Yes we use the open source project

right. so I'll reiterate that

there is no auth implemented for oss prefect server, api keys are for authenticating with prefect cloud

We have an app we used to serve as the auth in kubernetes, and pass the apikey through ui with a chrome extension which works. So my question is would sdk or rest api be the approach for us to use

sorry, not sure! it depends a lot on how you implemented auth on top of oss server i would talk to whoever did that for your server instance

Okay thanks Nate
