Trying to get binary data read into an HTTP receiver in BW 5.11

[Rob Perkins]

Im trying to use an HTTP reciever to be sent some encrypted data. The sample curl call i have is of the form

curl --request POST --data-binary @FILE "https://op.multiq.com/publiq/op/wclc.phpsignature=SIGNATURE

Where FILE contains the data.

In BW I cant figure out where this data would appear. I assumed it would be in the BinaryContent process data. But theres nothing there.

Any help would be appreciated.
