# Merchant Profiles

A Merchant Profile connects a [Merchant](/api/merchants) to its profiles, including a [Fee Profile](/api/fee-profiles), a [Payout Profile](/api/payout-profiles), and a Risk Profile.

Every Merchant has exactly one Merchant Profile. When a Merchant is created, a Merchant Profile is automatically generated and seeded with the profiles defined on the [Application Profile](/api/application-profiles). You can then update the Merchant Profile to assign a different Fee Profile or Risk Profile, overriding the application-level defaults for that specific Merchant.
