Creating a Payment

final paymentResponse = await posModule.createPayment(
  organizationCode: null,
  amount: 100.0,
  clientId: 'client_id',
  idempotenceKeyERN: 'idempotence_key_ern',
);

Creating a Refund

final refundResponse = await posModule.createRefund(
  organizationCode: null,
  amount: 50.0,
  retrievalReferenceNumber: 'reference_number',
  clientId: 'client_id',
  idempotenceKeyERN: 'idempotence_key_ern',
);

Creating a Service Operation

final serviceResponse = await posModule.createService(
  organizationCode: null,
  clientId: 'client_id',
  operationServiceType: OperationServiceType.SOME_TYPE,
  idempotenceKeyERN: 'idempotence_key_ern',
);

Abort operation

Abort operation is not async function, because it has not result data, bool flag is just result of success or unsuccess creation. The result of aborting the operation will be received in the operation that you aborted.

bool stopSuccess = posModule.createAbort(
  organizationCode: null,
  clientId: 'client_id',
  idempotenceKeyERN: 'idempotence_key_ern',
);
