This template uses the format \"_GLOBAL_NODE_NAME\" for globals, which can be accessed at any point after their execution with $('_GLOBAL_NODE_NAME').item.json\n- See examples in the blue section\n### Noop-nodes\n- No operation nodes help mark entry-points and make it easier to re-route sections\n### n8n restrictions (as of v 2.3.4)\n- webhooks with path variables automatically add a hash as url base\n- webhooks can only map 1:1 to a path level, so each level requires its own webhook"
