Google Adwords API always returns null...

[Akila17]

Hi,

I have just started using Adwords API, I downloaded the sample code
for V13.
I tried executing "add_keyword.php" and "get_keyword_variations.php"

I changed the login information to my gmail account info i.e.

$email = 'My gmail ID';
$password = 'My gmail Password';
$client_email = 'client_1+Same gmail id';
$useragent = 'Priyadarshini Technologies: AdWords API PHP Sample
Code';
$developer_token = 'My gmail id++INR';
$application_token = '';

When i execute "add_keyword.php" I get this message

New keyword with text "" and id "" was created.

And when i execute "get_keyword_variations.php" I get this message

List of additional keywords to consider has 0 variation(s). List of
popular queries with given seed has 0 variation(s).

What might be the reason for the above messages to be displayed.
Please advice.

Hello Akila,

If you're just getting started in AdWords API development using PHP,
I'd recommend that you try the APIlity client library:

http://google-apility.sourceforge.net/

It should be simpler than using any standalone sample code, and the
error reporting should be more robust as well.

Are you using APIlity? If so, can you try turning on debugging and
posting your sample request and response (with your login, password
and token information X-ed out)?
