Reference types help easily build cross-reference between Shopify objects by allowing users to select one or multiple handles based on the type of reference field.


There are 6 reference types in ACF. All values produced by ACF are either in string (non-repeatable field) or JSON string (repeatable field).



  • When attribute “Allow selection of multiple values” is checked, each value will be separated by |, for example: hello|world|2020, book|shoes|pen|eraser.


  • Product, Collection fields can be edited in the “Custom Fields” tab via Shopify resource picker.
