I have to grant access to Zencoder so you can connect to my server. What IP addresses do you use?
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.
If your files are also stored on an EC2 you can grant access to a Security Group to limit access to Zencoder. Security Groups are region specific, so make sure you pick the right one.
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.
