Data Looper

Created by Reachware Support, Modified on Thu, 2 Apr at 2:53 PM by Reachware Support

Data Looper repeats operations based on a count or condition, enabling pagination and repeated API calls. Essential for fetching large datasets page by page or processing data in batches. Use Data Looper to:

Fetch paginated API data (page 1, 2, 3...)
Process data in batches
Loop steps until a condition met

How to Add Data Looper

Click the Logic Processor icon between operations.

Select Data Looper.

Configure settings.

Click Save.

Configuration

Field	Description	Required
Data Looper Name	Name for this loop	Yes
Target	Last operation to include in loop	Yes
Repeat Count	Number of times to repeat	Conditional
Step Shift	Increment after each iteration	Yes
Repeat Condition	When to continue looping	Conditional

Important: You must provide either a Repeat Count OR a Repeat Condition (or both).

Target Operation

The Target defines the end of the loop.

Loop Scope

Step 1: Data Looper

↪

Step 2: Get Page Data

↪

Step 3: Process Data

↪

Step 4: Store Results

← Target

Hint: The loop repeats all steps between the Data Looper and the selected target (in this case, Steps 2, 3, and 4).

Repeat Count

Number of times to run the loop.

Options:

Fixed number: 10
Mapped value: {{total_pages}}
Handler result: ceil({{total_records}} / 100)

Example: Repeat Count: 5
// Loop runs exactly 5 times, then stops.

Step Shift

How much to increment the loop index after each iteration.

Common values:

1 — Increment by 1 (page 1, 2, 3...)
10 — Increment by 10 (0, 10, 20...)
100 — Increment by 100 (for offset-based pagination)

Example: Step Shift: 1
// Loop index: 0, 1, 2, 3, 4...

Hint: Step shift defines how much the loop index increases after each iteration.

Repeat Condition

Conditions that determine if the loop should continue.

The loop continues while the condition is TRUE.

Condition Types

Text Operators:

Equal, Not Equal to
Contain, Does Not Contain
Start With, Does Not Start With
End With, Does Not End With

Numeric Operators:

Equal, Not Equal to
Greater than, Greater than or equal to
Less than, Less than or equal to

Basic & Boolean:

Is Empty, Is not Empty
Equal (Boolean)
Not Equal to (Boolean)

Multiple Conditions

Combine conditions with AND/OR logic.

AND Example

{{has_more_pages}} = true AND {{current_page}} < 10

Both must be true to continue

OR Example

{{status}} = "pending" OR {{retry_count}} < 5

At least one must be true to continue
