The two parameters
When you enable Multi-Currency, the automatic backfill (see Multi-Currency Settings) rewrites your rule titles and descriptions using two placeholder tags:
{{ localCurrency }}
Replaces a specific monetary value and its currency symbol together — e.g. swaps "£15" or "€18" for the equivalent amount in the customer's local currency.
Requires the rule to have an identifiable monetary value attached to it (an earning value, a redeem cost, a tier threshold, etc.) — this is what Influence converts.
Works in: rule titles, tier titles, rule descriptions.
{{ localCurrencySymbol }}
Replaces just the currency symbol on its own (e.g. "£", "$") — without tying it to a specific monetary value on the rule.
Use this where you're referencing a currency in free text that isn't a value Influence can look up and convert — for example, a general-purpose earn rule description that says "spend £100 to unlock this," where the £100 isn't itself an earning value or threshold field.
Works in: rule titles, tier titles, rule descriptions.
Use {{ localCurrency }} whenever the number is an actual configured value on the rule.
Use {{ localCurrencySymbol }} when you're just localizing a currency symbol inside free-form text.
How the tags get applied
You don't need to add these tags manually. When the backfill runs, an AI scans each existing title/description and decides which tag (if any) is the appropriate replacement, based on how the text was written before. You can also use these tags yourself in any new rule title or description you write after enabling Multi-Currency.
What happens if Multi-Currency is off
If Multi-Currency is disabled, both tags always resolve to your store's base currency — regardless of what market the customer is browsing in. Nothing needs to be changed on the rules themselves; the tags simply fall back.
