I was hoping I could find a way to _get_ the custom field data, rather than just _set_ it, within InfusionSoft. There’s apparently lots of ways to change and update custom field data. What’s missing is a way to _get_ or _read_ that data, then perform functions based on that data.

I can _get_ custom field data with the API, then perform functions on my site or where ever, but can’t seem to find a way to do it in a campaign. I was hoping the decision diamond could at least fork campaigns based on custom field data, but even that seems missing.
