03/11/2024, 12:14 PMHi, My bot asks the user for the users information before opening a zendesk session. but there are senerios where the bot already has the information. and when it already does it would ask it unnecessary for a second time. How do i make a check for this? aka, when the bot already has the user.name it doesn't ask for the user information again but skips that step to open the zendesk session

03/11/2024, 1:42 PMIn my bots I create an expression card with the condition "workflow.variablename === '' so the bot will know if the variable is empty, it should ask the question you want, and if it's not, the conversation will go to a different path
