Unique Approval#


We started using the First Data API a couple of months ago. When using our previous API, we were sent back a unique approval/authorization number that we present to our customers and store on our end. Really just a unique reference#. When we switched to First Data, I was using the Authorization_Num for this, but have just realized this is not a unique value. Is there a unique reference# being sent back for approvals that I can use? I see the "Transaction Reference" number on the transaction page of the payeezy site, but did not see that value being returned in the approval response.

Thank you!

Re: Unique Approval#

You can capture the transaction tag as that will be unique and won't be reused. Authorization numbers are generated by the card issuing bank and are not always unique.
