How to use API Key for Outbound REST message ?

[Dina Shoukry]

I'm using one Outbound REST message. I want to use API Key from Connections & Credentials module as an Authentication type for my REST message. I have API Key in handy. Is it achievable ? I don't want to use basic or oauth authentication type.

In the Header Add

Authorization: Bearer <your API Key>

Unfortunately, it's not working for me 😞

I tried also

Authorization: Basic <API Key>

I'm trying this in the HTTP Headers of the rest message
