The /azure/store Robot

We export to the storage platform of your choice.

The /azure/store Robot exports encoding results to Microsoft Azure.


Name Type Default Description
use (required) String / Array of Strings


Specifies which Step(s) to use as the input to this Robot.

Special Step names

A special Step name is ":original", which provides user uploads handled by Transloadit.

Providing several Steps as input

You can add arrays to use several Steps:
"use": [

Step bundling

Some Robots can gather several Step results for a single invocation. For example, the /file/compress Robot would normally create one Zip file for each file passed to it. If you'd set bundle_steps to true, however, it will create one archive containing all the result files from all Steps you give it. To enable bundling, provide an object like the one below to the use parameter:
  "use": {
    "steps": [
    "bundle_steps": true
This is a crucial parameter for the /video/adaptive Robot, otherwise you'll generate 1 playlist for each viewing quality.
Keep in mind that all input Steps must be present in your Template. If one of them is missing, no result is generated because the Robot waits indefinitely for all input Steps to be finished.

Group by original

Sticking with the /file/compress Robot example, you can set group_by_original to true, in order to create a separate Zip file for each of your uploaded or imported files, instead of creating one archive containing all originals (or one per resulting file). This is a crucial parameter for the /media/playlist Robot.


See a demo for the use parameter here.
credentials (required) String Please create your associated Template Credentials in your Transloadit account and use the name of your Template Credentials as this parameter's value. They will contain the values for your Azure container, account and key. While we recommend to use Template Credentials at all times, some use cases demand dynamic credentials for which using Template Credentials with their static nature is too unwieldy. If you have this requirement, feel free to use the following parameters instead: "account", "key", "container".
path String "${unique_prefix}/${file.url_name}" The path at which the file is to be stored. This may include any available Assembly variables.
content_type String "" The content type with which to store the file. By default this will be guessed by Azure.
content_encoding String "" The content encoding with which to store the file. By default this will be guessed by Azure.
content_language String "" The content language with which to store the file. By default this will be guessed by Azure.
cache_control String "" The cache control header with which to store the file.
metadata String {} A JavaScript object containing a list of metadata to be set for this file on Azure, such as { FileURL: "${file.url_name}" }. This can also include any available Assembly variables.
sas_expires_in Integer / Null null Set this to a number to enable shared access signatures for your stored object. This reflects the number of seconds that the signature will be valid for once the object is stored. Enabling this will attach the shared access signature (SAS) to the result URL of your object.
sas_permissions String "" Set this to a combination of r (read), w (write) and d (delete) for your shared access signatures (SAS) permissions.
