Thank you so much for sharing this. This is exactly what I wanted to retrieve the data from Itune Connect.
I have a question about this code, since I am having this error, "Cannot index into a null array."

in here

Set the login data

$form = $r.Forms[0];
$form.Fields["theAccountName"] = "this-is-a-test@gmail.com";
$form.Fields["theAccountPW"] = "this_is_my_password";

for example my username is test@yahoo.com and my password is mysecretpassword,

so just change like this

Set the login data

$form = $r.Forms[0];
$form.Fields["theAccountName"] = "test@yahoo.com";
$form.Fields["theAccountPW"] = "mysecretpassword";

and then I assume that "theAccountName" and "theAccountPW" are "theAccountName" where I can see right above the screen and "theAccountPW same as above so I did like this

Set the login data

$form = $r.Forms[0];
$form.Fields["My Name"] = "test@yahoo.com";
$form.Fields["mysecretpassword"] = "mysecretpassword";

but it still causing error, how should I change it to work
Thank you so much and Happy Holidays
