Authorize.Net transaction id

[freedombi]

I have recently received the following email. Is this an issue for WHMCS?

 

Dear Authorize.Net Developer:

 

The Authorize.Net transaction ID is the payment gateway generated number

used to identify each transaction a merchant submits. The transaction ID

can be can be found in the transaction response. It can also be found using

the Search and Reports features of the Merchant Interface.

 

The transaction ID, or x_trans_id, is specified as a 10-digit integer. IF

YOU USE THE TRANSACTION ID IN ANY OF YOUR OWN APPLICATIONS OR DATABASES, IT

IS CRITICAL THAT YOU VERIFY THAT YOUR SYSTEM IS ARCHITECTED TO ACCEPT A

VALUE THAT EXCEEDS 2,147,483,647. FAILURE TO ACCOMMODATE VALUES LARGER THAN

2,147,483,647 WILL RESULT IN YOUR SYSTEM'S INABILITY TO ACCEPT

AUTHORIZE.NET TRANSACTIONS.

 

NOTE: This information only applies to you and your merchants if you are

currently using the Authorize.Net transaction ID.

 

If you need to make updates to your transaction ID architecture, you must

do so prior to September 1, 2008. In August, we will be notifying merchants

of this issue and instructing them to contact their Web developer to

determine whether or not it applies to them.
