CIM x_duplicate_window not working or no longer working

[hitesh4mail]

Hi All,

I have client having E-Commerc integrated with Authorized.Net with CIM.

Since recently we are experiencing duplicate transaction (Authorize) for many of customers.

I can replicate the issue on sandbox using PHP SDK.

I think it only works for 120 seconds then it allows duplicate transaction even if I pass greater value in extraOptions in x_duplicate_window parameter but it does not kick in.

As you can see duplicate transactions as in attached image

Hi hitesh4mail,

Please send an email to developer@authorize.net with your details (API login ID in question and sample transacton IDs). We would need to know how you are passing your request.

Thanks,

Joy
