Application Programming Interface (API)
When integrating with Authorize.net's APIs, your website or shopping cart must be able to reach our fully qualified domain names. We may reassign IP addresses without prior notice. Depending on your integration, you may need to allow list the domains or associated IP if using firewalls. If your integration also receives Webhooks from Authorize.net, you may want to allow list/verify the calls are coming from our Webhook IP Addresses. We advise against constructing a firewall rule based on IP GEO data as this information could change or may not be accurate.
For more information on our APIs and their status, please visit the Authorize.net Developer Center.
