I have successfully logged in Cobrand and User and set up DAG. I am trying to add an account with FMFA, but I end up with the error response as shown below.

        ]
      }
      }

ProviderId : 16445

Response:

{
  "errorCode": "Y400",
  "errorMessage": "Invalid value for login, site [DagSiteTokenFMPA]",
  "referenceCode": "f1493111410473e4L27n"
}

I need the response returned by this service so that I can model my iOS Application accordingly. If someone points out the APIs to hit in the correct order and the parameters for the API body.

From your request we can see the login form is not right. Please find the right login form-

Hope this helps.
