Prefect Community

Hi Community, I need a quick help in utilizing Prefect Orion's API from an existing Python application, I looked into the documentation to use the Prefect Orion Python Client but somehow I am having trouble using it. My existing stack has an FastAPI server running for a given application and I need to put in a feature that allows external users to use my existing API to run any Prefect Orion flows (my existing API could act as a proxy for the time being). Any suggestions?

Yes, I do have an example for you - you can trigger a flow run from deployment using Orion client as shown <https://discourse.prefect.io/t/how-to-create-a-flow-run-from-deployment-orchestrator-pattern/803|here>. You can make this call even from your existing FastAPI service
```response = await client.create_flow_run_from_deployment(depl_id)```

you can also directly check the source code <https://github.com/PrefectHQ/prefect/blob/orion/src/prefect/cli/deployment.py|here>
