OneSignal User Tags

Tag	Type	Description	Source
`shopify_segment_{segment_id}`	String	Membership flag (`"true"`) for each synced Shopify segment. One tag per segment. The `{segment_id}` is the numeric ID from Shopify’s segment GID.	server-side

Segment sync tags only identified users. You set up segment sync on the OneSignal Audiences tab of the Vendo Shopify app. Vendo updates enabled audiences every 15 minutes. Vendo tags only OneSignal users that already exist with a matching external_id (your Customer Identification value). It skips anonymous push subscribers and customers who are not identified to OneSignal yet. Run the sync again after large customer-acquisition windows, so that new subscribers get their segment tags.
