Send files via HTTP octet-stream

curl --location --request POST 'https://api.xxxxxxx.de/order/v1/...... \
--header 'x-apikey: .............' \
--header 'Content-Type: application/octet-stream' \
--header 'Content-Disposition: attachment; filename=Lieferschein.pdf' \
--data-binary '@/Users/Lieferschein.pdf'

I would like to make the above call from my Make scenario (cUrl from local machine)

I download the file that I want to upload from Google Cloud before.
Does anyone have an idea how I can make this call / how I can refer to the file?

Thanks

Try the http app. It has a download file module.
