1500 / 1510 Messages – Reconciliations

The 1500 / 1510 ISO message pair should not be used for dual message implementations of this protocol.

In a single message implementation, a 1500 reconciliation request message must be sent for each terminal in order to submit the captured transactions for settlement. The Elavon acquiring host system will respond with a 1510 reply.

Note that upon receipt of a 1500 reconciliation request message, the Elavon acquiring host will compare the totals it contains against those held by the host. If there is a mismatch, the Elavon acquiring host will return the totals it holds in the response. A response code (Field 39) of 501 – (Reconciliation Out of Balance) will be set, but the batch will be processed for funding and a new batch opened.

If a 1500 message is received where Elavon holds no items in a terminal batch, a response code (Field 39) of 133 (No Transactions) will be returned and the existing batch will remain open.

Please note: Multi-Currency Conversion (MCC) is not supported for Host Based solutions.
