Nothing available for magic text in custom action

I’m trying to create a custom action that gets a value from a third party. The API calls for an item id, and I have that available within the screen where I’m applying the action. However, when I build the custom action, the magic text says “Nothing available”. Is there something I’m missing here?

You need to add that option on the right side under “Inputs”.

hi,

Having same problem here. I want to pass a particular variable (symptomId) based on the user’s value. I do not want to hard code this. How do I dynamically set this query param?

Never mind. I managed to sort this out. Its confusing though
