Export files to MinIO

🤖/minio/store exports encoding results to MinIO buckets.

The URL to the result file will be returned in the Assembly Status JSON.

Usage example

Export uploaded files to my_target_folder on MinIO:

  "steps": {
    "exported": {
      "robot": "/minio/store",
      "use": ":original",
      "credentials": "YOUR_MINIO_CREDENTIALS",
      "path": "my_target_folder/${unique_prefix}/${file.url_name}"


  • use

    String / Array of Strings / Object required

    Specifies which Step(s) to use as input.

    • You can pick any names for Steps except ":original" (reserved for user uploads handled by Transloadit)

    • You can provide several Steps as input with arrays:

      "use": [

    💡 That’s likely all you need to know about use, but you can view Advanced use cases.

  • credentials


    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 MinIO bucket, Key, Secret and Bucket region.

    While we recommend to use Template Credentials at all times, some use cases demand dynamic credentials for which using Template Credentials is too unwieldy because of their static nature. If you have this requirement, feel free to use the following parameters instead: "bucket", "host", "key", "secret".

  • path

    String ⋅ default: "${unique_prefix}/${file.url_name}"

    The path at which the file is to be stored. This may include any available Assembly variables. The path must not be a directory.

  • acl

    String ⋅ default: "public-read"

    The permissions used for this file. This can be "public-read" or "private".

  • headers

    Object ⋅ default: { "Content-Type": "${file.mime}" }

    An object containing a list of headers to be set for this file on MinIO Spaces, such as { FileURL: "${file.url_name}" }. This can also include any available Assembly Variables.

    Object Metadata can be specified using x-amz-meta-* headers. Note that these headers do not support non-ASCII metadata values.

  • sign_urls_for


    This parameter provides signed URLs in the result JSON (in the signed_ssl_url property). The number that you set this parameter to is the URL expiry time in seconds.

    If this parameter is not used, no URL signing is done.

Note: The URLs in the result JSON already point to the file on your target storage platform, so you can just save that URL in your database.
