Hi Sergio,
With sandbox account in callback url the status shows as "ACCEPTED" and then I was able to call Accounts.adclients: get and after that created the ad units successfully
but with Live account in callback url the status shows as "ACCEPTED" but call to Accounts.adclients: get returns "Account not found".
When I call Accounts: get the status returned is PENDING
Is this normal behavioral difference between sandbox and live accounts?
In live account can adclients / ad units be fetched only when the account is approved?
Thanks in advance
