Condition Sets
Payflow conditions are organised into six sets. Each set maps to a dedicated Shopify Function extension, and only conditions within the same set (or across overlapping sets) can be used together in a single rule.
Why sets exist
Section titled “Why sets exist”Shopify Functions have a fixed input schema — each function can only access a specific subset of checkout data. To support 50+ conditions, Payflow distributes them across multiple function extensions. The result is that some condition combinations are available and others are not.
How combinations work
Section titled “How combinations work”- Within a set: all conditions can be freely combined.
- Across sets: some conditions appear in multiple sets. As long as there is at least one set that contains all your selected conditions, the combination works.
- Set 6 (Combined) is a cross-set function that includes frequently requested multi-set conditions.
If the combination you need is not available, contact support — new combinations can be added.
