In the checkout flow deliverySlaInMinutes delivery checkout along with the transaction details to the gateway, this data is calculated based on the shippingEstimate delivered by logistics, however when this value delivered by logistics is = 0 the checkout response for deliverySlaInMinutes is 0 null, when the correct one would be 0; however this ends up directly affecting the flow developed by the gateway for anti-fraud;

1- Create an order with Pick up 2- The shippingEstimate must be 0 3- Check the transaction data and see that the deliverySlaInMinutes is = null;

There is no direct workaround, however, if it is possible to avoid that the shippingEstimate delivered by logistic calculation, being equal to 0, it is possible to mitigate the scenario;
