# MerchantTransactionSummaryDto

A model the API reference uses in a request or a response. The operation pages link every field typed as this model here.

Per-merchant rollup of the transactions in the requested window.

## Fields
- `merchantId` (string(uuid)): The merchant the rollup belongs to.
- `merchantName` (string): The merchant's display name, or `null` when the name could not be resolved  (a merchant deleted after the transactions were taken, most commonly). The rollup is still  returned in that case so the amounts continue to reconcile. (nullable)
- `transactionCount` (integer(int32)): Number of approved transactions contributing to this rollup, counting both the sale side and  the credit side. Declined and in-flight transactions are excluded.
- `grossAmount` (number(double)): Sum of the approved sale-side amounts (authorization, sale, force, capture, capture-all and  repeat sale) in the merchant's transaction currency.
- `netAmount` (number(double)): `grossAmount` less the approved credit-side amounts (returns and voids). This is  the figure that reconciles against what the merchant is owed for the window.
- `transactionTypeCounts` (object): `transactionCount` broken down by transaction type, keyed by the  `TransactionType` member name (for example `Sale`, `Authorization`,  `Return`, `Void`). Types with no activity in the window are omitted rather than  carried as an explicit zero, so the keys present describe what the merchant actually did. (nullable)
