The /http/import Robot

We are happy to import from whatever storage solution suits you best.

The /http/import Robot imports any file that is publicly available via a web URL into Transloadit.

Parameters

Name	Type	Default	Description
`url`	(required) String / Array of Strings		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.
`url_delimiter`	String	`"\|"`	Provides the delimiter that is used to split the URLs in your `url` parameter value.
`headers`	Array of Strings	`[]`	Custom headers to be sent for file import. This is an empty array by default, such that no additional headers expect the necessary ones (e.g. Host) are sent.
`force_name`	String / Null	`null`	Custom name for the imported file. Defaults to `null`, which means the file name is derived from the supplied URL.
`ignore_errors`	Boolean	`false`	There might be an error coming up when importing files or trying to extract meta data from them. Setting this to `true` will cause the Robot to not stop the import (and the entire Assembly) when that happens. This is especially useful when you use an array of URLs for the `url` parameter and thereby import several files at once.

Live demos

Our /http/import Robot can be used in combination with other Robots, to create powerful workflows unique to your use case.
Here are a few example scenarios, and the required Assembly Instructions to implement them.
You can also try demos of these examples right here, live on our website.
