Unauthorized - when posting messages to event mesh queue

[RaviRIyer]

I was able to post messages to a rest API Endpoint for event mesh but i am not able to get past the Unauthorized error. 

I have tried to redo the entire setup from scratch several times, followed several blogs but not able to get past the 403 error when posting from postman. 

has anyone seen and resolved this, would be great if you can share details....

when i post to the endpoint - https://enterprise-messaging-pubsub.cfapps.sap.hana.ondemand.com/messagingrest/v1/queues/<Queue name>/messages with a bearer token i am getting an unauthorized. how do i get around this ?

i activated the default plan and created a service key, and from the service key - used the client id and secret and the token endpoint and got a bearer token. 

I used this bearer token to post to the URL and keep getting an unauthorized- did i miss anything ?

{

    "error": {

        "code": "UNAUTHORIZED",

        "message": "Unauthorized"

    },

    "message": "Unauthorized"

}

i cleaned out the entire configuration, and redid it from scratch, and it works to send the query to get a token, but when i use the token in the second request to post to a queue, i still get unauthorized. Any thoughts ?
