Objective: Populate Facebook Catalogue product custom labels (e.g., CL0/custom_label_0) with Google variant IDs to enable cross-platform performance matching.
Status: Multiple attempts to fill these custom label fields have failed; the labels are not appearing in the Facebook Catalogue as intended.
Suggestion offered: Create dynamic ads and apply custom labels to the marketing catalogue. This guidance was acknowledged but clarified as not addressing the specific need to populate the product-level custom_label fields in the catalogue.
Clarification: The request targets Facebook Catalogue’s product details fields (custom_label_0–custom_label_4), not campaign-level labels. A screenshot of the product details interface is central to understanding the exact fields in question.
Latest development: Another participant asked whether a solution was found, indicating ongoing interest for audience targeting based on these labels.
Outcome: No confirmed method or steps were provided to populate the product-level custom_label fields with Google variant IDs. The discussion remains open.
Open question: How to map or feed Google variant IDs into Facebook Catalogue’s custom_label_0–custom_label_4 via the sales channel or product feed so they reliably appear in the catalogue.
