using acf with zapier

i’m trying to connect zapier to my cptui/acf custom post type to create new posts with content from a spreadsheet populating my custom fields. i can assign the custom post type and get the custom field content into the Content area, but i can’t seem to access the advanced custom fields to populate. is this possible? i’m trying to build a speaker directory with different custom fields for topics and bios and youtube links. thanks.
