Starting February 13th, if you create a column via the API with a title of 20 characters or less, the column ID will relate to the title. For example, if your column title is This is my column, then the column ID will be this_is_my_column.
If your title is more than 20 characters, the system will randomly generate a column ID based on the column_type and an ongoing index. It will not be related to the column title.
This update will only impact new columns, not existing ones!
