hello @txh3467, thanks for asking this question on Community!!
just to confirm, what are you referring to with the prefix for the column??
if you’re looking for the name, you can use the https://{instance}.tulip.co/api/v3/tables/{tableID} endpoint. this is returns all columns (including the name and label):
in this case, you can see the name,
"name":string"fgpdf_date"
"label":string"Date"
"description":string""
is this what you were looking for?? let us know!!
