Unable to retrieve datasets - got Error message Infrastructure problem (403): Access is denied

I'm not sure the steps your using when calling the API endpoint, but I can share what i've had success with. I was recieving the 400 error as well. 

Step 1: Create a client within the developer portal under my account "new client". (assuming you already did, just trying to help others)

Step 2: Navigate to the below URL and enter the Client ID and Secret.

https://developer.domo.com/explorer#!/auth

• Once you enter the Client ID and Secret, you will see your Authorization code within the Request box.
  • Example: 

    Authorization: Basic YWZ3ZWY6yourcodehere

  • Note: I was getting the error calling the endpoint using the response token, it expires. I decited instead to use .JS and request a new token each time the endpoint is called, using the above Authorization code (it doesn't change).

Example:

 var tokenOptions = {
"method": "GET",
"hostname": "api.domo.com",
"port": null,
"path": "/oauth/token?grant_type=client_credentials&scope=data%20user",
"headers": {
"Accept":"application/json",
"Authorization": "Basic EnterYourTokenHere" 
}};

Step 3: Create a script that will call the above endpoint using the Request authorization code. Once the call completes, capture the response token and call the secondary datasets endpoint. The response will include a JSON containing the DS listing. 

I hope this helps with testing your access. Attached is the code I used to call the datasets, just add your authorization code.

Same issue here.  Any help would be appreciated.  I just cannot get the dataset (schema) although I can get the data.  I have tried updating my client scope but that didn't make any difference.

Thanks in advance.
