GraphQL Examples

In this repository you'll find some examples of using our GraphQL API.

Authentication

Create a new application.
Get an authorization code after signing in with the application.
Get an access token with the authorization code.

Details

export APPLICATION_ID=...
export APPLICATION_SECRET=...
export REDIRECT_URI=...
export AUTHORIZATION_CODE=...

curl --url 'https://www.universe.com/oauth/token' \
  --header 'content-type: application/json' \
  --data "{\"grant_type\":\"authorization_code\", \"client_id\":\"$APPLICATION_ID\", \"client_secret\":\"$APPLICATION_SECRET\", \"redirect_uri\":\"$REDIRECT_URI\", \"code\":\"$AUTHORIZATION_CODE\"}"

Here is a quick demo which demonstrates how to get an access token at Universe in 1 minute:

For more information about OAuth 2.0, please see our guide.

Queries

Viewer

Viewer is the user who makes the current GraphQL request. To see the account information:

cURL example

export ACCESS_TOKEN=your_access_token

curl https://www.universe.com/graphql/beta \
  -H "Authorization: Bearer $ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d @- << EOF
{
  "query": "query GraphqlExample {
    viewer {
      id
      firstName
      lastName
    }
  }"
}
EOF
# => {
#   "data": {
#     "viewer": {
#       "id": "58d98e52bbdebd003804e065",
#       "firstName": "Evgeny",
#       "lastName": "Li"
#     }
#   }
# }

Ruby example

require 'net/http'
require 'uri'
require 'json'

def graphql(query, access_token)
  uri = URI.parse('https://www.universe.com/graphql/beta')
  http = Net::HTTP.new(uri.host, uri.port).tap { |h| h.use_ssl = true }
  headers = {'Authorization' => "Bearer #{access_token}", 'Content-Type' => 'application/json'}
  request = Net::HTTP::Post.new(uri.path, headers)
  request.body = {query: query}.to_json
  http.request(request).body
end

access_token = 'your_access_token'

puts graphql(
  "query GraphqlExample {
    viewer {
      id
      firstName
      lastName
    }
  }",
  access_token
)
# => {
#   "data": {
#     "viewer": {
#       "id": "58d98e52bbdebd003804e065",
#       "firstName": "Evgeny",
#       "lastName": "Li"
#     }
#   }
# }

List of Events

With the Host.id, it's possible to get the list of all Events:

cURL example

export HOST_ID=4f5e06cb2078f9730c000014

curl https://www.universe.com/graphql/beta \
  -H "Content-Type: application/json" \
  -d @- << EOF
{
  "query": "query GraphqlExample {
    host(id: \"$HOST_ID\") {
      name
      events {
        totalCount
        nodes {
          id
          title
        }
      }
    }
  }"
}
EOF
# => {
#   "data": {
#     "host": {
#       "name": "Joshua Kelly",
#       "events": {
#         "totalCount": 1,
#         "nodes": [
#           {
#             "id": "5879ad8f6672e70036d58ba5",
#             "title": "End of Unix Time"
#           }
#         ]
#       }
#     }
#   }
# }

Ruby example

require 'net/http'
require 'uri'
require 'json'

  request = Net::HTTP::Post.new(uri.path, {'Content-Type' => 'application/json'})
  request.body = {query: query}.to_json
  http.request(request).body
end

host_id = '4f5e06cb2078f9730c000014'

puts graphql(
  "query GraphqlExample {
    host(id: \"#{host_id}\") {
      name
      events {
        totalCount
        nodes {
          id
          title
        }
      }
    }

#           }
#         ]
#       }
#     }
#   }
# }

Event

With the Event.id, it's possible to get Event information with the TimeSlots:

cURL example

export ACCESS_TOKEN=your_access_token
export EVENT_ID=5879ad8f6672e70036d58ba5
