From the post:
Using the Neo4j REST API
After starting the Neo4j server, load the HTTP console by clicking here. The HTTP console uses the Neo4j REST API to interact with the database. Even though you can use the HTTP shell for manually interacting with the database, it is best used for prototyping the REST calls your app would be making to the database. Unless Neo4j provides bindings for your language (Java, Python, Ruby), you will most probably be using the REST API to talk to the database.
For your reference, the Neo4j documentation is located at http://docs.neo4j.org/chunked/stable/.
Let’s see how some of the common operations can be performed in Neo4j Nodes and Relationships using the REST API.
Excellent post on the Neo4j REST API.
The one improvement I would suggest is one of presentation. Code/responses that run off the viewable page aren’t very helpful.
