The A/B Test node lets you split callers between two different paths in your workflow.
This is useful for experimenting with variations — such as different prompts, voices, flows, or logic — and measuring which performs better. Traffic is split once per caller using sticky assignment, meaning a returning caller will continue down the same variant they were originally assigned to.

​
Main Settings

​
Probability to A (%)

Controls what percentage of callers should go to Variant A.
  • Range: 0–100%
  • Whatever is not routed to A automatically goes to Variant B
Examples:
  • 50% → even split
  • 90% → most callers go to A
  • 0% → all callers go to B
This setting only determines distribution—both branches can contain any nodes you want.

​
Outputs

The A/B Test node provides two output connectors:
  • A → callers assigned to Variant A
  • B → callers assigned to Variant B
Connect each output to the next node in that variant’s flow to define your experiment branches.
