The Assign node is essential in workflows for managing data transformations and storage. It allows users to assign fixed values or the results of expressions to outputs or variables, streamlining data flow and facilitating dynamic decision-making within workflows.
Assign Fixed Values: Directly set specific values to variables or output fields.
Map Data Between Variables: Transfer or transform data from one variable to another using simple assignments or complex mappings.
Expression Evaluation: Evaluate expressions and assign the result to variables, enabling dynamic and conditional data handling.
Data Initialization: Initialize variables with specific values at the start of a workflow to ensure they are ready for use.
Dynamic Calculations: Use expressions to perform calculations and assign the result to a variable for later use in the workflow.
Data Synchronization: Map data from inputs to internal workflow variables to maintain consistency and integrity across different workflow stages.
The Switch node is designed to direct the workflow based on conditional logic, allowing for branching based on case evaluations. This node evaluates a series of cases, each defined by a specific set of conditions, and branches the workflow accordingly.
Case Evaluation: Each case within the node has a set of conditions. The workflow branches off when these conditions are met.
Default Case: If no conditions are met for any case, the workflow defaults to a predefined path, ensuring that the workflow continues smoothly.
Visibility of Case Fulfillment: It is possible to track whether each case's conditions have been met, providing clarity and transparency in workflow execution.
All Winning Cases: This strategy evaluates all cases that meet their conditions. If no cases are deemed profitable, the default case is executed.
First Winning Case: This strategy identifies and executes the first case that meets its conditions. If no cases qualify, the default case is executed.
Complex Decision Making: Ideal for scenarios requiring multiple conditions to determine the workflow path.
Error Handling: Can be used to manage different error conditions and direct to appropriate recovery paths.
User Input Handling: Direct workflow based on various user inputs or actions within a system.
This node is crucial for implementing complex decision-making capabilities within workflows, allowing for dynamic and condition-based workflow branching.

The Foreach node is used for iterating over arrays within a workflow, making it essential for processing collections of data. This node utilizes a "Loop Connector" to iterate through each item in the input array, providing powerful functionality for data manipulation and analysis.
Loop Connector iterates over every item in the specified input array, ensuring that each element is processed sequentially.
Access to Current Item: during each iteration, the current item is accessible via the [foreach node name].currentItem attribute, allowing for direct manipulation of each array element as an object.
Iteration Context provides additional iteration parameters such as:
index: Indicates the number of the current iteration.
length: Indicates the total length of the input array.
For nested arrays, multiple Foreach nodes can be nested within each other. This allows for the handling of complex data structures and multi-dimensional arrays with ease.
Data Processing: Ideal for scenarios requiring detailed processing or transformation of each item within an array.
Batch Operations: Efficient for performing operations on batches of data, such as calculations, filtering, or aggregation.
Complex Data Structures: Useful in workflows that need to navigate and manipulate nested or hierarchical data structures.
This node is crucial for workflows that involve array processing, providing robust tools for iterating over data and applying specific operations to each element effectively.
The Sticky Note node is used to create notes within the workflow. This node serves as a simple yet effective way to add annotations, comments, or reminders directly in the workflow, enhancing clarity and communication among team members.

Visibility: Notes are visible within the workflow interface, making it easy for anyone reviewing the workflow to understand the context and reasoning behind specific nodes.
Non-Functional: This node does not affect the workflow's execution; it is purely for documentation and informational purposes.
Documentation: Use Sticky Notes to document the logic and reasoning behind complex workflow sections.
Collaboration: Facilitate better communication among team members by adding notes that explain specific parts of the workflow.
Reminders: Add reminders for future modifications or considerations that need to be addressed.
This node is essential for maintaining clear and comprehensive documentation within your workflow, ensuring that all stakeholders understand the workflow's structure and intent.
The End node serves as a visual indicator for the termination of a workflow branch and provides insight into the final data state of that branch. While not mandatory, as output mapping can be achieved with the Assign node, the End Node adds value by enhancing workflow clarity and inspection.
Workflow Inspection: Displays the data associated with the relevant workflow path in the inspector, offering a clear view of the output data and making it easier to debug and verify the workflow's final state.
Optional Use: The End node is optional and is primarily used to provide a clear endpoint for workflow branches. This helps in enhancing organization and readability but does not replace nodes like the Assign node for output mapping.
The End node is beneficial for workflows that require distinct termination points and a way to easily inspect final data states, ensuring both ease of use and enhanced workflow clarity.
The Business Rule node allows you to connect and execute various types of business rules such as decision tables, decision trees, rule flows, or even entire workflows. This node is versatile and can operate in two distinct modes to accommodate different use cases.
Static Mode: Select a specific business rule and, optionally, a particular version of that rule.
Dynamic Mode: Select a business rule and its version based on workflow variables. If no version is explicitly selected, the latest published version of the rule is used.
You can choose from different solving strategies for evaluating business rules and determining the format in which the results are returned:
Standard
Always returns an array of results from the solved business rule.
Automatically attaches a Loop connector to the node, allowing iteration over the results.
During iteration, the current item is accessible via [node name].currentItem, and the iteration index is available via index.
All returned data in the array is accessible through [node name].output.
Evaluates All
Similar to the Standard strategy but specifically evaluates all rows in a decision table.
Returns an array of results and allows for iteration as in the Standard strategy.
First Match
Returns a single output object containing the result data.
This strategy does not return an array but a single object representing the first matching result.
Decision Automation: Ideal for scenarios where complex business logic needs to be automated through decision tables or trees.
Dynamic Rule Selection: Useful when the specific business rule or its version needs to be selected based on runtime conditions.
Batch Processing: Employ the Standard or Evaluates All strategies to handle multiple results from business rules, enabling batch processing and comprehensive evaluations.
This node is pivotal for integrating complex business logic into your workflows, ensuring that decisions are made based on the latest rules and data.
Array append involves adding elements to an existing array. Unlike merging, where elements are combined from two different arrays, appending adds new elements to the end of an array.
Let's say you have an existing JSON array:
Now, you want to append a new element to this array:
After appending, the resulting array would be:
In this appended array:
The original elements remain unchanged.
The new element { "id": 3, "name": "Bob" } is added to the end of the array.
Joining two JSON arrays by a key involves combining the arrays based on a common identifier or key within the JSON objects.
Let's say you have two JSON arrays:
You want to join these arrays based on the "id" key. After merging, the resulting array should contain all unique elements from both arrays, with matching elements combined based on the "id" key. If an element exists in one array but not the other, it should still be included in the merged array.
In this join array:
The object with id equal to 1 exists in both arrays, so their properties are joined into one object.
The object with id equal to 2 only exists in the first array, so it's included as is.
The object with id equal to 3 only exists in the second array, so it's included as is.
