Blank response from all APIs

Media API
1

I’m using the CloudLink API with an OAuth Client Token password grant_type. A 3rd Party MSP has configured the system and set me up.

My issue I’m finding is that all APIs are returning no results.

  1. Auth to https://authentication.api.mitel.io/2017-09-01/token with password grant and given account id
  2. Call GET https://media.api.mitel.io/2017-09-01/calls/records with access token from above. Returned below.

{
“_links”: {
“self”: “/2017-09-01/calls/records”
},
“count”: 0
}

Are there any steps I’m missing my side? I’m using the postman setup out of the box.
