Reacting to events

Reacting to events
Reactions can be used to trigger external services when certain events occur.
The following example shows the basic APIs for working with reactions.
Create event reaction definition  
As an example, we are going to set up a reaction that posts notifications every time an order is placed. We need to specify the feed name and the event type to react to.
We use a POST command to configure our reaction:
cURL
1
curl -i https://api.serialized.io/reactions/definitions \
2
  --header "Content-Type: application/json" \
3
  --header "Serialized-Access-Key: <YOUR_ACCESS_KEY>" \
4
  --header "Serialized-Secret-Access-Key: <YOUR_SECRET_ACCESS_KEY>" \
5
  --data '

  {
7
    "reactionName": "new-order-notifier",
8
    "feedName": "order",
9
    "reactOnEventType": "OrderPlacedEvent",
10
    "action": {
11
      "actionType": "HTTP_POST",
12
      "targetUri": "https://some-server.com"
13
    }
14
  }
15
  '

Next time an OrderPlacedEvent happens you will get a POST request to your some-server.com looking something like this:
1
{  
2
   "metadata":{  
3
      "aggregateId":"723ecfce-14e9-4889-98d5-a3d0ad54912f",
4
      "timestamp":1505376578800,
5
      "sequenceNumber":1
6
   },
7
   "event":{  
8
      "eventId":"127b80b5-4a05-4774-b870-1c9a2e2a27a3",
9
      "eventType":"OrderPlacedEvent",
10
      "data":{  
11
         "customerId":"some-test-id-1",
12
         "orderAmount":12345
13
      }
14
   }
15
}
Copied!
