Thanks for this. It is working when reading the account details of the master account. However, when I use it to view billing information, I receive a 2001. Account does not exists error.
I guess we have to request higher privileges through ISV? Thanks.
That’s correct, if you haven’t yet requested a master/sub account set up, you’ll need to first request this to be able to utilize the Billing endpoints. For this, you can email firstname.lastname@example.org.
