protected video. This system allows you to restrict access to a specific
video or subset of videos, to a specific IP address, timeframe and usage
count.

Request Fields
command |
[REQUIRED] [string] - API command to execute |
cdn |
[REQUIRED] [int] - The ScaleEngine CDN ID of your
account |
api_key |
[REQUIRED] [string] - The API key provided as part of your
account |
timestamp |
[REQUIRED] [int] - The unix timestamp of your request, used to
prevent authenticated API requests from being replayed |
app |
[REQUIRED]
- [string] - The ScaleEngine Application name to restrict
viewing to
- [string] - A pipe separated list of applications, optionally
with wildcards.
Example: myapp-vod|otherapp-*
|
video |
[REQUIRED]
- [string] - The stream name or path of the VOD video
the user is restricted to. VOD examples look like like:
sestore3/username/path/filename.mp4
- [string] - One of more stream name or VOD path separated by
a pipe, optionally with wildcards. This allows for things
like multi-bitrate streams or files, or allowing users
access to a group of streams and videos.
Example: mystream_* will match mystream_720p and
mystream_360p.
Example: file1.mp4|file2.mp4 will only allow the
listed files to play
Example: sestore3/username/set1/*|sestore3/username/set2/*
will match any file in those directories
|
pass |
[REQUIRED] [string] - A randomly generated password. Should be
unique for each request. Recommended length atleast 10
characters. |
ip |
[REQUIRED]
- [string] - The IP address to allow access from
- [string] - The CIDR mask of a range of IP addresses to
allow access from.
Example: 192.168.0.0/24
Example: 0.0.0.0/0 allows any IP address
- [string] - The literal string 'auto' or 'auto/24'. This will
update the ticket the first time it is used to restrict it
to the IP address of the user. This will prevent account
sharing, while at the same time dealing with edge cases such
as users behind corporate firewalls or proxies that may have
a different IP address on the website than they will use to
access the video stream
|
uses |
[REQUIRED] [int] - The number of times the video will be allowed
to start. This can be used to restrict how many times a ticket
may be used, and helps further protect against account sharing |
expires |
[REQUIRED] [datetime] - The expiration date of the ticket. After
this time, access will no longer be allowed, the user will
require a new ticket.
Example: 2024-10-15 15:41:26 |
