Hi @alexli126 ,

Afraid not, You could try watching tutorials on youtube: How to set up Promotions Feed in Google Merchant Center? (youtube.com) or How to add a Promo ID to products in the supplement feed – Multiple Google Shopping feeds Knowledge Base (woolytech.com)

The promotion ID, is unique and usually found in the promotional feed that you made on google merchant Centre. You can always reach out to Google’s support team on where you can get such values.
