Hi @dinithij - The API will not give you dynamic results for things like formula and progress columns. You’ll need to pull in the column settings and generate the values on your end from what you find in the settings.
We built an app that uses both formula and progress columns to prioritize cards on a board view, and @Spunkie may be able to add more context as well. It will take more coding on your end to reproduce the dynamic functionality.
Perhaps if we’re lucky the next version of the API will include dynamic values.
