Environment variables and config options

Two separate mechanisms carry Galaxy settings, depending on which code reads them:

Name	Read by	Where it's set	Purpose
GALAXY_API_KEY	scripts/import_workflow.py, scripts/test_galaxy_roundtrip.py	.env in this repo, loaded via uv run --env-file .env	Your usegalaxy.eu API key, for the standalone scripts only.
GALAXY_WORKFLOW_ID	scripts/test_galaxy_roundtrip.py	.env, printed by import_workflow.py	The imported workflow's ID, for the standalone scripts only.
GALAXY_API_KEY	resolve_api_key (actions/find_peaks/resolve.py)	An environment variable on the NOMAD worker process	Fallback used when the /actions trigger form's galaxy_api_key field is left empty. Same variable name as above, different process reading it — the form field always wins if set. See Explanation > Handling secrets for why.
galaxy_workflow_id	FindPeaksActionEntryPoint (__init__.py)	nomad.yaml's plugins.entry_points.options for nomad_eosc_galaxy_actions.actions.find_peaks:find_peaks_action	The Action's own copy of the workflow ID. No default — must be set for the Action to run at all. See Install This Plugin.
galaxy_url	FindPeaksActionEntryPoint (__init__.py)	Same nomad.yaml options block as above	Base URL of the Galaxy instance. Defaults to https://usegalaxy.eu; override for a different Galaxy instance.

The two GALAXY_API_KEYs are unrelated in practice: one is read by short-lived standalone scripts you run yourself, the other by the long-running NOMAD worker. Set both if you use both paths — setting one doesn't set the other.
