Hey @noobiangodd

I've been able to reproduce the exact same issue on my side.

Seems like they updated their backend... I tried real quick to add the missing field, but :

I don't have much time to find a workaround for now, the whole thing was working because they implemented themself a captcha bypass for their chrome extension ("nope" in the recaptcha field)

I'll let you know once I have time to dig a bit more this problem.

I am currently working on a workaround.

@Blutsh
While I wait to find a way to bypass SwissTransfer's reCAPTCHA, I set up an API to use gofile.io and unblock my bot.

You should explore the mobile application: multiplatform-SwissTransfer
In particular, the endpoint used here: https://www.swisstransfer.com/api/mobile/containers

[Blutsh]

Yep,

Had a quick look on source code of multiplatform-SwissTransfer :

In order to query the mobile endpoint we need to call AppIntegrity / InfomaniakDeviceCheck (android / IOS) to get an attestation token which is then verified server side.

This is not doable here.

feels bad but for now this tool is only useable for download, -> will update readme.
