Yes, the signature comes from postman. i try it in another tool and it works. but if i try it in bubble it does not work. below you can see the raw text, the api connector and the other tool so you can compare. i literealy copy and paste the same. i do not know what else to change to make it work!
The problem is not the authorization key since i copy it directly from postman and it works in req bin. For some reason the exact same code does not work in bubble.
I have figured out already how to generate the authorization key but i first need to make the call work 
Thanks for your help!
