In the blockchain ecosystem, "events" refer to important actions or changes within the blockchain network.

This includes things like creating or changing digital assets, transferring balances, and any other actions that alter the chain's state. These events are recorded on the blockchain, providing a transparent and unchangeable history of all activities.

Monitoring and analyzing these events helps users and developers understand the flow of transactions and respond to specific actions or conditions in the network. This is key for decentralized applications and games, enabling automated interactions and improving overall functionality.

Note on Address Formats in Platform Events
Please note that all account addresses included in platform events, such as channel names or any addresses within the event payload, are formatted as public keys.
For example, in a "Transfer" event, the "from" account address appears in its public key format.
If needed, you may use the Account Format Transform tool to convert between SS58-encoded address format (e.g., "cx...123" for the Canary Matrixchain or "cn...123" for the Canary Relaychain) and public key format.

Using Enjin Platform

To view events emitted from a transaction conducted on the platform, you can use the GetTransaction query as follows:

query GetTransaction {
  GetTransaction(id: 40000) {
    method
    state
    result
    events {
      edges {
        node {
          moduleld
          eventId
          params {
            type
            value
          }
        }
      }
    }
  }
}

{
  "data": {
    "GetTransaction": {
      "method": "BatchTransfer",
      "state": "FINALIZED",
      "result": "EXTRINSIC_SUCCESS",
      "events": {
        "edges": [
          {
            "node": {
              "moduleId": "Balances",
              "eventId": "Withdraw",
              "params": [
                {
                  "type": "who",
                  "value": "f64fda4cb0352aff9394f0cc14495ca8cefffb8c8e9b37de058a1d4d4650c3313"
                },
                {
                  "type": "amount",
                  "value": "20675071170417823"
                }
              ]
            }
          },
          {
            "node": {
              "moduleId": "MultiTokens",
              "eventId": "CollectionAccountCreated",
              "params": [
                {
                  "type": "collection_id",
                  "value": "2155"
                },
                {
                  "type": "account",
                  "value": "303049fa4535f21acc5760521c6cc91f01ddf28ebf771da99effbf5c1031416F"
                }
              ]
            }
          }
        ]
      }
    }
  }
}

Our platform broadcasts network events through a WebSocket channel, similar to the recent events feature in Polkadot-JS. It's important to note that this channel includes not only network-wide events but also specific events from the Enjin Platform.

Our platform uses WebSockets to transmit real-time events, but since WebSockets can sometimes be unstable, there's a risk of missing events if your system loses connection. To address this, we also cache events in a query called GetPendingEvents. The most effective way to stay updated in real time and ensure no events are missed is to always acknowledge the events you receive.

query GetPendingEvents {
  GetPendingEvents(
    acknowledgeEvents: false,
    first: 50
  ) {
    edges {
      node {
        name
        data
      }
    }
  }
}

{
  "data": {
    "GetPendingEvents": {
      "edges": [
        {
          "node": {
            "name": "platform:transaction-updated",
            "data": {
              "id": 179419,
              "state": "PROCESSING",
              "method": "BatchTransfer",
              "result": null,
              "transactionId": null,
              "idempotencyKey": "4eace652-9c9f-4721-bfe3-1be6f7597c32",
              "transactionHash": null
            }
          }
        },
        {
          "node": {
            "name": "platform:transaction-updated",
            "data": {
              "id": 179417,
              "state": "PROCESSING",
              "method": "BatchTransfer",
              "result": null,
              "transactionId": null,
              "idempotencyKey": "a3e62297-983e-4a14-81a9-975976302127",
              "transactionHash": null
            }
          }
        }
      ]
    }
  }
}

Using Enjin Console

In the explorer tab, you can find the recent events emitted in the network. Those will appear as soon as they are emitted.

You can also see the events emitted in a single block by querying the block directly
