title: Issue with making transaction in Neo4J Python
body: <p>I am trying to send a POST request with a Neo4j transaction query. Although I get a response 200 the node is not created. This is my Python script:</p>
  
  <pre><code>import requests
  import json
  import csv
  
  headers = {'content-type': 'application/json'}
  url = "http://localhost:7474/db/data/transaction/commit"
  
  
  
  checkNode = {"query" : '{"statements": [{"statement":"CREATE (n:test) RETURN n"}]}'}
  mkr =requests.post(url, data=json.dumps(checkNode), headers=headers)
  
  print(mkr)
  </code></pre>
  
  <p>I haven't used transactions before and nver tried to create one through the Rest Api. What am I doing wrong here?</p>
