For `url` marketplace sources, the documentation now says the helper may print HTTP headers as a JSON object. Before, it described only the helper's output being used as the `Authorization` header.\n\n**Why**\n\nAdmins can authenticate to a marketplace that needs custom headers, not just a single Authorization header.\n\n- Area: Plugins\n- Names: `credentialHelper`\n- Tier: Use it now\n- Useful: 3\/5\n- Signal: 2\/5\n- Scope: both\n- Heads-up: no"}
