Payment duplication challenge

I've been receiving DUPLICATE_CHALLENGE on my ICloverConnectorListener#onConfirmPaymentRequest that I don't understand how those could be considered a possible payment duplication.

Here's the situations I get a DUPLICATE_CHALLENGE:
Make a payment of 100, complete it. Make another payment of 200 with same card
Make a payment of 100, complete it. Make another payment of 100 with same card

Looks like any transaction in a row with the same card will be considered a possible payment duplication?

I'm setting a different requestId and externalId on every new transaction. Shouldn't that prevent this suspected duplication?

Hi Dyegocosta,

It looks like the duplication logic flags any payment with an hour that has the same first / last 4 on the credit card. The logic is not customizable.

Thanks,
Miguel
