How can I copy a file from a URL into S3?


We want to enable someone to enter a URL and then hit a button to have the file copied into our own S3 bucket. We already have a database full of such URLs that need migrated, as well as new adhoc URLs.

How should I go about that?

Hey @richard!

Happy to help here! Do these URLs directly return a file in a specific format? Would you mind sharing an example here?

Hi Chris,

The URLS just point to files sitting on a webserver. e.g.

We want to be able to upload that source file into S3 and save the new URL into our database, via a retool command or process.

We'd also like to be able to arbitrarily enter URLs to files and click a button and have the file uploaded to S3 in a similar way.

Does this clarify?


Hey @richard!

Sorry for the slow reply here. Are these files going to be consistently the same type (always a pdf)? If so, you could set up a GET query to the original URL, this should return a JSON object with 3 keys:

base64Binary, fileName, and fileType. From here, you can use this binary to pass to an upload query:

In this case, I'm passing the binary directly with the S3 Content-Type set to binary and the upload file name including the matching extension. Once this query is run, it should return a signed url that you can include in your url upload query

Do you think this could work for your use case here?\

Works perfect here. Both from url and plain base64Binary generated at pdfotter api, to direct upload S3.

As a straightforward solution, you can use Resilio Sync or Gs Richcopy 360 to copy directly to AWS S3, try the free version of both
