Types of Nodes - Tooljet

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 data received by the Start Trigger through parameters is accessible throughout the workflow.

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

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.
