permalink I have to grant access to Zencoder so you can connect to my server. What IP addresses do you use?

File Transfers

Zencoder runs on Amazon EC2 instances, so there's a wide range of IP addresses that we use for File and Live transcoding. Amazon regularly adds new ranges to the list, which can be found via the AWS IP Range API.

Notifications

Notifications are currently sent from sg-77f03012, but this could change at any time. In order to account for this, we've added a X-Zencoder-Notification-Secret header to all notifications delivered. This can be found on the API dashboard, where you can see your current secret and generate a new one if necessary.

This header is delivered with every request and can be used to guarantee that the notification was delivered from your Zencoder account. Note: In order to keep your notification secret secure, make sure to deliver notifications to HTTPS endpoints!

Note: Servers may move to new datacenters, and IP addresses may change without notice.
