# Node Configuration

## Overview
Documentation for Node Configuration integration and usage within the KeeperHub ecosystem.

[Nodes](https://docs.keeperhub.com/keepers)

This guide covers how to configure nodes in the KeeperHub workflow builder.

Click any node on the canvas to open its configuration panel on the right side of the screen. The panel shows all available settings for that node type.

### Required Fields
Fields marked with an asterisk (*) are required. The workflow cannot run until all required fields are completed.

### Common Fields
All nodes share these configuration options:

### Scheduled Trigger
Custom Cron: Enter a cron expression for precise scheduling (e.g., 0 9 * * 1-5 for weekdays at 9 AM).

`0 9 * * 1-5`

### Webhook Trigger
Copy the webhook URL and configure your external service to POST to it.

### Manual Trigger
No additional configuration needed. Click the Run button to execute.

### Read Contract
KeeperHub automatically fetches the contract ABI from block explorers. For proxy contracts, it detects the proxy pattern and fetches the implementation ABI automatically. Supported proxy standards include EIP-1967, EIP-1822 (UUPS), OpenZeppelin Transparent Proxy, EIP-1167 (minimal proxy), and Gnosis Safe. For EIP-2535 Diamond contracts, KeeperHub queries the Diamond Loupe interface to discover all facets and combines their ABIs into a single unified interface.

### Write Contract
Important: Write operations require ETH in your Para wallet for gas fees.

Available Operators:
- Equals (==)
- Not equals (!=)
- Greater than (>)
- Greater than or equal (>=)
- Less than (<)
- Less than or equal (<=)
- Contains (for strings)

Connections store credentials for external services. Set them up before configuring nodes that require them.

### Adding a Connection
1. Click your profile icon in the top-right corner
2. Select Connections
3. Click Add Connection
4. Choose the connection type
5. Enter the required credentials
6. Save the connection

### Using Connections in Nodes
When configuring a node:
1. Select the Connection field
2. Choose from your saved connections
3. The connection status shows as a green checkmark if valid

## Dynamic Variables
Use dynamic variables in notification messages to include data from your workflow:

`${balance}`

`${address}`

`${network}`

`${timestamp}`

`${workflow_name}`

Example Message:

`Balance Alert: ${address} on ${network} has ${balance} ETH`

`Balance Alert: ${address} on ${network} has ${balance} ETH`

## Enabling and Disabling Nodes
Each node has an Enabled toggle:
- Enabled: Node executes when the workflow runs
- Disabled: Node is skipped during execution
This allows you to temporarily disable parts of a workflow without deleting them.

## Deleting Nodes
Click the Delete button at the bottom of the configuration panel to remove a node. This also removes all connections to and from that node.
