If you reference variables in your GraphQL document, the value for variables MUST be a JSON object containing the key/value pairs for each variable as can be seen below.

JSON

{
 "query": "a GraphQL document goes here that references $var1, $var2, and $var3",
 "variables": {
   "var1": 10,
   "var2": { "some": "data", "for": "var2" },
   "var3": ["a","list","of","values"]
 }
}

To send that to our API, it has to be wrapped in a JSON object with a query key:

Text

{ "query": "query { hello }" }

...

cURL

curl  -H 'Content-Type: application/json'  -X POST https://staging-ignite.originate.ng/graphql -d '{"query": "query { hello }"}'
