separation:
  mechanism: per-environment base host + per-environment API key
  key_header: x-api-key
  notes: >-
    Sandbox and production are addressed by distinct hostnames (dev vs app), each
    requiring its own x-api-key. In the Compass product a separate API key is issued
    per workspace and must be routed into the x-api-key header for the target workspace.
test_values: []
notes: >-
  Merkle Science issues API keys directly rather than via self-service, so no public
  test credentials or magic identifiers are published. Test-vs-live separation is by
  host + key. No invented test values are recorded.
