How to send Auth parameter in the header while calling the Rest endpoint?

Hi,

I am trying to post Json data to a Rest web service. I couldn’t send the Bearer authorization token to the routing address. I set Authentication Method as None on the Routing Address. I sent the authorization token by a header parameter. However, the header parameter is not seen on the Application Message. Then, the response message returned the “401: Unauthorized access” message. What is the problem?

Routing Address

Application Message

The Script

DECLARE
	access_token_ VARCHAR2(5000) := ifsapp.sfn_bt_variable_api.get_degisken_degeri('MEDITEK_WS_TOKEN');
	options_      VARCHAR2(5000);
	bxml_         CLOB;
BEGIN
	options_ := 'Authorization: Bearer ' || access_token_;
	dbms_output.put_line(options_);
	bxml_ := '{
