Hi,

I want to connect to Buckaroo. The autorisation is a bit tricky. The header item 'Autorization', is a collection of data and then transformed and coded by hmac256.

One of the items is the request body. The actual json message I want to send with the post. I don't know how I can get this to an expression. How can I get this information in the header? 

I hope someone has done this before!
