Can two sites be live with the same API Login ID and Transaction key?

[Marcy]

We are working on a new site to replace an old one (different domain names). On the old site, authorize.net is live and well and working. On the new site, I am in testing sandbox mode.

We would like to have authorize.net go live on the new site while remaining live on the old site during the transition.

Can we use our one account, the same API login ID and transaction key, on both sites?

Thanks.

As a corrolary to this, do you think we should go live with authorize.net then transition to the new site, or transition first and then go live with authorize.net?

We are planning to have the second site ultimately use the old site's domain name and the old site will go away.

Thanks.

Sure.  We have several live services using the same login ID and transaction key.

The only thing you might need to adjust is your " Authorized API IP Addresses " if you have white-listed specific servers. (Hidden setting under Fraud Detection Suite)
