Any idea how to get Neo4j data from Oracle PLSQL procedure?

I had idea to use HTTP API with query:

 `CALL db.index.fulltext.queryNodes("ProductNameIndex", "product_name: yppytyynytyydytys") YIELD node, score`
 `RETURN node.product_name as prod_desc, score`

But for some reason JSON with such command is not accepted by Neo4j http api.
Can I communicate, directly, with Neo4j in other way? Some curl?


The HTTP API should accept any valid Cypher query. Is there any error returned that could indicate why it does not work?
