If you are following the directions here:  
[https://dev.blues.io/reference/notecard-walkthrough/inbound-requests-and-shared-data/#adding-inbound-notes-with-the-notehub-io-api](https://dev.blues.io/reference/notecard-walkthrough/inbound-requests-and-shared-data/#adding-inbound-notes-with-the-notehub-io-api)

but the response from Notehub is

```auto
400 bad request, cannot be fulfilled ...

```

then the request is using an invalid username and password combination.
