Issue in consuming Ariba open API

Dear Experts,

Need your inputs in resolving below issue.

"No API key found in Request" error message is shown while trying to access the Ariba Requisition approval API in Fiori application.

Please find the attached screenshots of the Destination configured in HCP, Destination path update in Neo-app.json and the Ajax call made using the configured Destination to retrieve a single PR item from Ariba client specific tenant.

Also attaching the error seen in Browser Network tab and the request , response details in Postman client.

Please let me know where I'm doing wrong.

Regards,

Parthibaraja
