Types of Nodes

Nodes are graphical representations of each process in a workflow. Each node can access the data from the nodes that were executed earlier. Every workflow contains key node types that help orchestrate the flow of data and logic.

Start Trigger Node​

The Start Trigger node is the entry point of your workflow. It can be triggered:

  • Manually through ToolJet applications similar to queries
  • Via webhooks from external systems

The Start Trigger receives data through parameters, which can be used in any node of the workflow. You can also set default values using Test JSON parameters. These defaults will be used if no values are provided when the workflow is triggered from the app builder or a webhook.

Logic Nodes​

JavaScript Node​

The JavaScript node lets you write custom server-side code to:

  • Transform data
  • Perform complex calculations
  • Create custom messages
  • Handle business logic

The code must include a return statement to pass results to subsequent nodes.

If Condition Node​

The If condition node enables branching logic with:

  • One or two incoming flows
  • Two outgoing flows (true/false paths)
  • Logical expressions for decision making

When the condition evaluates to true, the outgoing node connected to the green arrow will be executed. If it is false, the outgoing node connected to the red arrow will be executed.

Loop Node​

The Loop node allows you to:

  • Iterate over datasets
  • Process items sequentially
  • Apply operations to each item
  • Aggregate results

Data Source Nodes​

Data source nodes connect to your configured data sources, enabling you to:

  • Execute database queries
  • Make API calls
  • Send emails/messages
  • Interact with external services

Each data source node has specific configurations based on its type:

  • PostgreSQL: SQL query fields
  • REST API: HTTP method, endpoint, headers
  • Twilio: SMS configuration fields
  • And more based on your configured sources

Workflow Node​

The Workflow node is used to trigger another workflow from within a workflow. Parameters can also be passed to another workflow.

note
  1. A workflow can call itself recursively. It’s recommended to define an exit condition to avoid an infinite loop.
  2. The timeout for each workflow can be configured using the WORKFLOW_TIMEOUT_SECONDS environment variable, for more information checkout Customizing Workflow Configuration.

Response Node​

The Response node defines the final output of your workflow. You can configure multiple response nodes to return multiple execution results.

Each node type serves a specific purpose in the workflow. By combining these nodes, you can create powerful automation flows tailored to your business needs.

Node Operations​

Error Handling​

The Error Handling node operation in ToolJet workflows lets you define different execution paths based on whether a node succeeds or fails. If a node runs successfully, the workflow continues along the success path, if it fails, the error path is triggered, allowing you to perform custom actions like logging, notifications, or retries.

Copy​

The Copy operation lets you copy a node’s configuration to your clipboard. You can then paste it into another part of the workflow or a different workflow for quick reuse.

Duplicate​

The Duplicate operation instantly creates a copy of the node in the same workflow. This helps speed up building workflows with similar nodes without reconfiguring from scratch.

Delete​

The Delete operation removes a node and its connections from the workflow. Use this to clean up unused or obsolete nodes and keep your workflow organized.
