Calling the GitHub web API

We can use apoc.load.jsonParams to load a JSON file from a web API, setting the HTTP request headers in the second parameter of this procedure:

CALL apoc.load.json("neo4j_neo4j_contributors_github.json") YIELD value AS item
MATCH (u:User {login: item.login})
CALL apoc.load.jsonParams(item.followers_url, {Authorization: 'Token ' + $token}, null) YIELD value AS contrib
MERGE (f:User {login: contrib.login})
CREATE (f)-[:FOLLOWS]->(u)

When performing the import, I got the following results:

Added 439 labels, created 439 nodes, set 439 properties, created 601 relationships, completed after 12652 ms.
