Flow control

Conditional Block

Conditional evaluates a switch value, checks cases in order, and follows the first matching branch or the default branch.

Branching logic

Operators

Equals, contains, greater/less, starts/ends

Output

Optional evaluated value

Error handle

Yes

What it does

Conditional lets one Flow path split into different branches. It evaluates a configured switch expression and compares it with ordered cases.

The first matching case wins. If no case matches, the default path runs.

Use it when

Handle empty versus non-empty extraction results.
Route by status text, category, price, or page state.
Use a fallback path when a value does not match expected cases.

Do not use it when

Every branch should run; use separate connected paths instead.
You need repeated iteration; use Loop.
The switch value has not been created before this Block runs.

Settings

Conditional needs a switch expression and one or more cases. Cases are checked top-to-bottom.

Switch value

Required: Yes

Variables: Yes
Description: Value to test. Use variables or literal text.

Cases

Required: Yes

Variables: Case values can use variables
Description: Ordered conditions with operators and branch handles.

Default path

Required: No

Variables: No
Description: Path followed when no case matches.

Output variable

Required: No

Variables: Variable name
Description: Stores the evaluated switch value when configured.

Setting	Required	Variables	Description
Switch value	Yes	Yes	Value to test. Use variables or literal text.
Cases	Yes	Case values can use variables	Ordered conditions with operators and branch handles.
Default path	No	No	Path followed when no case matches.
Output variable	No	Variable name	Stores the evaluated switch value when configured.

Outputs

Conditional can save the evaluated switch value.

{{outputVariableName}}any

The evaluated value, when an output variable is configured.

matchedCasestring

Runtime result describing which case matched.

Example Flow

Use Conditional after extraction or calculation when the next step depends on the value.

Create or extract a value.
Evaluate it with Conditional.
Run the matching branch or default branch.

Errors and fixes

Start with symptoms visible in the editor or Inspector, then check the earliest Block that produced the wrong page state, variable, or output.

The wrong branch runs.

Check: Check case order and the exact evaluated switch value.
Fix: Move the most specific cases higher or adjust the operator.

No case matches.

Check: Inspect the switch value in Inspector mode.
Fix: Add a matching case or connect the default path.

Symptom	Check	Fix
The wrong branch runs.	Check case order and the exact evaluated switch value.	Move the most specific cases higher or adjust the operator.
No case matches.	Inspect the switch value in Inspector mode.	Add a matching case or connect the default path.

Local and cloud runs

Local and cloud runtimes both evaluate cases in order. Local only writes the switch output when configured; cloud may also report a generated conditional result.
