The /ftp/store Robot

We export to the storage platform of your choice.

The /ftp/store Robot exports encoding results to your FTP servers. No public key authentication is required. This Robot relies on password access.

Parameters

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

General

Specifies which Step(s) to use as our input.

Special Step names

A special Step name is ":original", which provides user uploads handled by Transloadit. Outside of this restriction you can pick your own names.

Providing several Steps as input

You can add arrays to use several Steps: 
"use": [
  ":original",
  "encoded",
  "resized"
]
:bulb: That's likely all you need to know about use, but you can view advanced use cases:
› Advanced use cases

Step bundling

Some Robots can gather several Step results for a single invocation. For example, the /file/compress Robot would normally create one archive 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": [
    ":original",
    "encoded",
    "resized"
  ],
  "bundle_steps": true
}
This is also 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 (for instance it is rejected by a filter), no result is generated because the Robot waits indefinitely for all input Steps to be finished. Here's a demo that showcases Step bundling.

Group by original

Sticking with the /file/compress Robot example, you can set group_by_original to true, in order to create a separate archive for each of your uploaded or imported files, instead of creating one archive containing all originals (or one per resulting file). This is important for for the /media/playlist Robot where you'd typically set: 
"use": {
  "steps": [
    "segmented"
  ],
  "bundle_steps": true,
  "group_by_original": true
}

Fields

You can be more discriminatory by only using files that match a field name by setting the fields property. When this array is specified, the corresponding Step will only be executed for files submitted through one of the given field names, which correspond with the strings in the name attribute of the HTML file input field tag for instance. When using a back-end SDK, it corresponds with myFieldName1 in e.g.: $transloadit->addFile('myFieldName1', './chameleon.jpg'). This parameter is set to true by default, meaning all fields are accepted. Example: 
"use": {
  "steps": [ ":original" ],
  "fields": [ "myFieldName1" ]
}

Use As

Sometimes Robots take several inputs. For instance, the /video/merge Robot can create a slideshow from audio and images. You can map different Steps to the appropriate inputs. Example: 
"use": {
  "steps": [
    { "name": "audio_encoded", "as": "audio" },
    { "name": "images_resized", "as": "image" }
  ]
}
Sometimes the ordering is important, for instance, with our concat Robots. In these cases, you can add an index that starts at 1. You can also optionally filter by the multipart field name. Like in this example, where all files are coming from the same source (end-user uploads), but with different <input> names: Example: 
"use": {
  "steps": [
    { "name": ":original", "fields": "myFirstVideo", "as": "video_1" },
    { "name": ":original", "fields": "mySecondVideo", "as": "video_2" },
    { "name": ":original", "fields": "myThirdVideo", "as": "video_3" }
  ]
}
For times when it is not apparent where we should put the file, you can use Assembly Variables to be specific. For instance, you may want to pass a text file to the /image/resize Robot to burn the text in an image, but you are burning multiple texts, so where do we put the text file? We use specify it via ${use.text_1}, to indicate the first text file that was passed. Example: 
"watermarked": {
  "robot": "/image/resize",
  "use"  : {
    "steps": [
      { "name": "resized", as: "base" },
      { "name": "transcribed", as: "text" },
    ],
  },
  "text": [
    {
      "text"  : "Hi there",
      "valign": "top",
      "align" : "left",
    },
    {
      "text"    : "From the 'transcribed' Step: ${use.text_1}",
      "valign"  : "bottom",
      "align"   : "right",
      "x_offset": 16,
      "y_offset": -10,
    }
  ]
}
credentials (required) String Please create your associated Template Credentials in your Transloadit account and use the name of your Template Credentials as this parameter's value. They will contain the values for your FTP host, user and password. While we recommend to use Template Credentials at all times, some use cases demand dynamic credentials for which using Template Credentials with their static nature is too unwieldy. If you have this requirement, feel free to use the following parameters instead: "host", "user", "password".
path String "${unique_prefix}/${file.url_name}" The path at which the file is to be stored. This can contain any available Assembly variables. Please note that you might need to include your homedir at the beginning of the path.
port Integer 21 The port to use for the FTP connection.
url_template String "https://{HOST}/{PATH}" The URL of the file in the result JSON. The following Assembly variables are supported.
ssl_url_template String "https://{HOST}/{PATH}" The SSL URL of the file in the result JSON. The following Assembly variables are supported.

Demos

Our /ftp/store Robot can be used in combination with other Robots, to create powerful workflows unique to your use case. Here are a few example scenarios that you can try live on our website:

Pricing

Transloadit is a SaaS with a subscription model.

Just like with any File Exporting Robot, you can use our /ftp/store Robot free of charge, as long as you also perform some processing (encoding, resizing, etc). If you do not, and Transloadit is just moving files, we still offer a considerable discount of 90%, effectively counting only every tenth byte of files that you export with /ftp/store.

Just like with your mobile plan, pricing goes down considerably when you commit to larger monthly volumes. You can adjust this every month. More info and available plans on our Pricing page.
