  title: Amazon Neptune openCypher Create and Read Node
  summary: Create a node over the openCypher HTTP endpoint, then read nodes back to confirm the write.
  description: >-
    A write-then-verify pattern over the Neptune openCypher HTTP endpoint. The
    workflow creates a node with the supplied label and name using a CREATE
    statement submitted as a form-encoded query, then runs a MATCH query to read
    nodes back and confirm the write landed. Both requests use the
    application/x-www-form-urlencoded content type required by the openCypher HTTP
    endpoint. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
