FXP Tiers

Create an improvement tier

Creates an improvement tier for a source currency. A tier defines a threshold and an improvement in basis points that applies to your base rate for transactions at or above that threshold. If a live tier already exists for the same source currency and threshold, it is automatically superseded. When Nexus generates a quote, it selects the tier with the greatest threshold that does not exceed the transaction amount, and adds tier and PSP improvements together in basis points before applying them, so improvements never compound. An idempotency key header is recommended. Requires the scope tiers.write. Used by: FX Providers (FXPs)
