Hi Noriko,   Looks like you are trying to pass api\_key/secret as a JSON payload. v1 of the API takes them as query parameters or form data. Please try that. ---

Looks like you are trying to use Master Account APIs. If your account is not setup this way, they will not work for you. ---

Master accounts are a special type, they have the ability to create accounts (not users) underneath them. These type of accounts and that ability is usually preserved for resellers/partners.  ---
