# Create sub-merchant fee override

`POST /api/connect/accounts/{subMerchantId}/fees`

Creates a per-sub-merchant fee override that fully replaces global MarketplaceSettings for payins and deposits. Use 0 rates/fixed amounts for zero-fee commercial gestures.

## Path parameters

- `subMerchantId` string, required

## Request body

- CreateSubMerchantFeeOverrideDto
  - `marketplaceFeeRatePer1000` number — Marketplace take rate on the gross payin amount. Effective rate = value / 100_000. Examples: 2500 = 2.5%, 0 = no percentage fee.
  - `marketplaceFeeFixedInCents` number — Flat marketplace fee in cents charged on every payin.
  - `marketplaceDepositFeeRatePer1000` number — Marketplace take rate on virtual-account deposits. Effective rate = value / 100_000.
  - `marketplaceDepositFeeFixedInCents` number — Flat marketplace fee in cents charged on every deposit.
  - `marketplaceFeeBearer` 'SUB_MERCHANT' | 'MARKETPLACE' — "SUB_MERCHANT" creates an obligation per payin/deposit. "MARKETPLACE" means no obligation — the marketplace absorbs the fee.
