You can use conditions on the transitions between steps in order to manage what's next and how it gets triggered in the pathway.
How to add a condition
Create a new transition and click on it
Press "+ Add Condition" at the top
Select the data point in the drop-down list you want to use for the condition
Select the correct operator for your condition. This depends on the type of question you've used.
In some cases, you'll need to specify the operand for your condition.
You can add multiple conditions to one transition. The different conditions can be separated by an AND or an OR statement. A combination of both isn't possible. Please read this article for a possible workaround.
You can also add delay to a transition. Find out here how to do so.
