Orchestrator REST Header Token

Hello, we are running JDE 9.2 with tools release 9.2.4.3 and AS/400 as database.

I have issues getting a token from a SAP system.

I have been instructed to invoke an endpoint $metadata with a GET and pass this information in the header of the Rest call: x-csfr-token fetch. After creating the connection I use it in the connector. The GET seems to work as it does return me the contract but I don't know how to retrieve the token from the header information.

The header value passed at the beginning remains unchanged.

Doing he same with PostMan works, from the same browser (Google Chrome).
