Getting 400 bad request on testing the MerchandiseReturn POST

[sleekoptions]

Hi,

I am working on VisaNet QR and payment links for invoices

So, I used Visa Direct API for this

Where I have created new project and saved private key and client certificate and Certificate Authority root certificate

Added API Key and shared secret using RSA/ECB/OAEPWithSHA-256AndMGF1Padding

Upon Postman

Checking MerchandiseReturn POST

url:  https://sandbox.api.visa.com/visadirect/mvisa/v1/mr

using Basic Authorization:

used body as json

I was getting a 400 Bad request. Saying {

    "responseStatus": {

        "status": 400,

        "code": "9125",

        "severity": "ERROR",

        "message": "Expected input credential was not present",

        "info": ""

    }

}

Can Anyone help me what other credentials do I need in this case
