Import files from web servers
🤖/http/import imports any file that is publicly available via a web URL into Transloadit.

}The result of this Robot will carry a field import_url in their metadata, which references the URL from which they were imported. Further conversion results that use this file will also carry this import_url field. This allows you to to match conversion results with the original import URL that you used.
This Robot knows to interpret links to files on these services:
Instead of downloading the HTML page previewing the file, the actual file itself will be imported.
Import an image from a specific URL:
Controls whether Assembly Variables are interpolated for individual instruction fields.
By default, most Robot instruction fields interpolate Assembly Variables. Set this to false to treat every instruction field as literal text, or set an individual field path to false to treat only that field as literal text. For Robot-specific fields that are literal by default, set this to true or set that field path to true to opt back into interpolation.
Use field names such as path, or dotted paths such as ffmpeg.vf for nested objects.
Allows you to specify a set of metadata that is more expensive on CPU power to calculate, and thus is disabled by default to keep your Assemblies processing fast.
For images, you can add "has_transparency": true in this object to extract if the image contains transparent parts and "dominant_colors": true to extract an array of hexadecimal color codes from the image.
For images, you can also add "blurhash": true to extract a BlurHash string — a compact representation of a placeholder for the image, useful for showing a blurred preview while the full image loads.
For videos, you can add the "colorspace: true" parameter to extract the colorspace of the output video.
For videos, you can also add "interlaced": true to detect whether the video is interlaced. This combines the cheap ffprobe field_order flag with a bounded idet sampling pass over the first frames of the source, exposing interlaced, field_order, and a diagnostic interlace_detection object under file.meta. This is computationally expensive and billed accordingly.
For audio, you can add "mean_volume": true to get a single value representing the mean average volume of the audio file.
You can also set this to false to skip metadata extraction and speed up transcoding.
Whether the results of this Step should be present in the Assembly Status JSON
Setting the queue to 'batch', manually downgrades the priority of jobs for this step to avoid consuming Priority job slots for jobs that don't need zero queue waiting times
Force a Robot to accept a file type it would have ignored.
By default, Robots ignore files they are not familiar with. 🤖/video/encode, for example, will happily ignore input images.
With the force_accept parameter set to true, you can force Robots to accept all files thrown at them.
This will typically lead to errors and should only be used for debugging or combatting edge cases.
Custom name for the imported file(s). By default file names are derived from the source.
Setting this to ["meta"] will still import the file on metadata extraction errors. ignore_errors is similar, it also ignores the error and makes sure the Robot doesn't stop, but it doesn't import the file.
The URL from which the file to be imported can be retrieved.
You can also specify an array of URLs or a string of | delimited URLs to import several files at once. Please also check the url_delimiter parameter for that.
Provides the delimiter that is used to split the URLs in your url parameter value.
Custom headers to be sent for file import.
This is an empty array by default, such that no additional headers except the necessary ones (e.g. Host) are sent.
Headers can be specified as:
The same headers value is sent with every URL in this /http/import Step. If url is an
array, headers is not matched to the URLs by array index. Use separate /http/import Steps
when different URLs need different headers.
Disable the internal retry mechanism, and fail immediately if a resource can't be imported. This can be useful for performance critical applications.
Maximum allowed size in bytes for each imported file. If the remote server reports a larger file size, the import is rejected before the download starts. If the remote server does not report a size upfront, the download is aborted once this limit is exceeded.
If set to true, the Robot will not yet import the actual files but instead return an empty file stub that includes a URL from where the file can be imported by subsequent Robots. This is useful for cases where subsequent Steps need more control over the import process, such as with 🤖/video/ondemand. This parameter should only be set if all subsequent Steps use Robots that support file stubs.
Allows you to specify one or more byte ranges to import from the file. The server must support range requests for this to work.
Single range: Use a string like "0-99" to import bytes 0-99 (the first 100 bytes).
Multiple ranges: Use an array like ["0-99", "200-299"] to import multiple separate ranges. The resulting file will contain all requested ranges concatenated together, with zero bytes (\0) filling any gaps between non-contiguous ranges.
Range formats:
"0-99": Bytes 0 through 99 (inclusive)"100-199": Bytes 100 through 199 (inclusive)"-100": The last 100 bytes of the fileImportant notes:
