Understanding Transaction Types

The RMO Merchant API supports multiple types of monetary transactions. Understanding these types ensures proper integration and reduces payment errors.

Authorization

Checks whether funds are available. No money moves.

Capture

Transfers funds after a successful authorization. Supports partial captures.

Sale

Performs authorization and capture in a single step.

Void

Cancels an existing authorization before it is captured or settled.

Refund

Returns funds to the member after settlement. Supports partial refunds.

Reversal

Cancels a same-day captured transaction before settlement (if enabled on your account).

Each type uses a dedicated endpoint in /merchant/v1/transactions.
