@HCP is right. I edited my original post.
The https://blockchain.info/merchant/xxxxxxx keeps redirecting you back to the Blockchain API doc page.
Topic: Blockchain api key (Read 156 times)
Don't you have to install a service on your local machine to use the API? 
I don't think you can connect to: https://blockchain.info/merchant
To use this API, you will need to run small local service which be responsible for managing your Blockchain Wallet. Your application interacts with this service locally via HTTP API calls.

I'm getting NULL when running the code:

Install and run the local service and make the requests to it.
The base URL for all requests is:https://blockchain.info/merchant/$guid/ "https://localhost:3000/merchant/$guid" where $guid is your Blockchain Wallet ID (used to login), and you should use the parameter "?password=main_password" where main_password is your wallet password.
Here is an example for PHP:
$guid="GUID_HERE"; // YOUR WALLET ID
$firstpassword="PASSWORD_HERE"; // YOUR PASSWORD
$secondpassword="PASSWORD_HERE"; // SECOND PASSWORD IF YOUR ACCOUNT HAS DOUBLE ENCRYPTION ENABLED
$amounta = "10000000";
$amountb = "400000";
$addressa = "1A8JiWcwvpY7tAopUkSnGuEYHmzGYfZPiq";
$addressb = "1ExD2je6UNxL5oSu6iPUhn9Ta7UrN8bjBy";
$recipients = urlencode('{
"'.$addressa.'": '.$amounta.',
"'.$addressb.'": '.$amountb.'
}');
$json_url = "http://localhost:3000/merchant/$guid/sendmany?password=$firstpassword&second_password=$secondpassword&recipients=$recipients";
$json_data = file_get_contents($json_url);
$json_feed = json_decode($json_data);
$message = $json_feed->message;
$txid = $json_feed->tx_hash;

It should already be linked if you got it from your account on blockchain's website.
I received an api key from blockchain, I'm using it to create unique addresses so I can receive payments, how do I link that api key to my blockchain wallet account
