18.5.1. Set property on node

Setting different properties will retain the existing ones for this node. Note that a single value are submitted not as a map but just as a value (which is valid JSON) like in the example below.

Example request

  • PUT http://localhost:7474/db/data/node/17/properties/foo
  • Accept: application/json
  • Content-Type: application/json
"bar"

Example response

  • 204: No Content

18.5.2. Update node properties

This will replace all existing properties on the node with the new set of attributes.

}

Example response

  • 204: No Content

18.5.3. Get properties for node

18.5.5. Property values can not be nested

Nesting properties is not supported. You could for example store the nested json as a string instead.
