Counts and totals the transactions matching a filter, three ways.

POST /api/transactions/reports/statistics deprecated

Requires: Transactions.Reports, merchant scope.

Folds every transaction matching the filter into count and total amount, grouped by transaction type, by payment type and by result code. The three groupings partition the same rows, so each one sums to the overall figures.

Every block below sends the same request. Replace {{BASE_URL}} with the address of the API you are calling and {{API_KEY}} with your own key.

Parameters

Name	In	Type	Description
`suppressNulls` required	query	boolean	If true, omit properties with null values.

Request body

application/json , required

Field	Type	Description
`merchantId` required	string (uuid)	Optional merchant to restrict the aggregate to. When omitted, the result covers every merchant the caller is entitled to see. A merchant outside the caller's scope yields an empty result rather than an error, because the caller is not entitled to learn whether it exists. nullable
`minCreationTime` required	string (date-time)	Inclusive lower bound on the transaction's creation time, in UTC. nullable
`maxCreationTime` required	string (date-time)	Exclusive upper bound on the transaction's creation time, in UTC. nullable
`filter` required	all of FilterGroup	The filter tree, in the same vocabulary the transaction continuation list accepts, including its virtual fields (`PaymentMethod`, `DisplayGuid`, `EntryMode`, `SettlementBatchId` and the rest), which are resolved server-side exactly as the list resolves them.

This request body has no documented fields.
