Overview
This node integrates with a blockchain events API to listen for new blocks on specified blockchains and networks. It is designed to trigger workflows when a new block is detected, enabling automation based on blockchain activity.
Common scenarios include:
- Monitoring blockchain networks for new blocks to update databases or dashboards.
- Triggering alerts or notifications when new blocks are mined.
- Initiating downstream processes such as transaction analysis or asset tracking upon block creation.
For example, you can configure the node to watch the Ethereum mainnet and automatically process data whenever a new block is added, helping keep your application synchronized with the blockchain state.
Properties
| Name | Meaning |
|---|---|
| blockchain | The blockchain network to monitor (e.g., Ethereum, Bitcoin). |
| network | The specific network within the blockchain (e.g., mainnet, testnet). |
| context | Optional string to provide additional context or metadata for the event subscription. |
| JSON Body | A collection of optional parameters: |
| - allowDuplicates | Boolean flag to allow duplicate event notifications. |
| - callbackSecretKey | Secret key used to secure callbacks from the blockchain event service. |
| - callbackUrl | URL to which the blockchain event notifications will be sent. |
Output
The node outputs JSON data representing the details of the newly detected block. This typically includes block metadata such as block number, hash, timestamp, and other relevant blockchain-specific information.
If configured with a callback URL, the node may also handle incoming webhook data corresponding to new block events.
No binary data output is produced by this node.
Dependencies
- Requires an active connection to the Crypto APIs REST API service.
- Needs an API authentication token configured in n8n credentials to authorize requests.
- The node reads a local OpenAPI specification file (
2024-12-12-final.json) bundled with the node for operation definitions. - Network access to the blockchain event service endpoints is necessary.
Troubleshooting
- Operation not found error: If the node throws an error stating that the operation was not found, ensure that the selected Resource and Operation are valid and supported by the current version of the node.
- Authentication errors: Verify that the API key credential is correctly set up and has sufficient permissions.
- Invalid parameters: Double-check required properties like
blockchainandnetworkare provided and correctly spelled. - Callback URL issues: If using a callback URL, ensure it is publicly accessible and properly secured if a secret key is used.
- Duplicate events: If receiving duplicate block events, consider setting the
allowDuplicatesproperty accordingly.
