How to combine 2 JSON values to then send in a follow-up request?

Hi there,

I have a situation with an authorization token that I need to use for subsequent requests.
So, from my first request I get a json response in the form of a token as two different properties e.i. 
tokenType: Bearer
Token: 7yw7adwadaawaw9d9

Now all of my follow up requests need to contain these values in one header in the request, like this:
Authorization: Bearer 7yw7adwadaawaw9d9

Now, I have tried to use the Property Transfer option but it doesn't seem to work because it only allows me to send one json property in the header of my future requests, so my question is:
Can I somehow combine the two properties to come together exactly like in the example mentioned above and send them in that Header, like that?


Any help would be greatly appreciated.
Thank you very much
