How to implement Braintree escrow
<p>I want to implement escrow of Braintree in my website. But escrow is not holding. My code is </p>

<pre><code>`require_once "lib/Braintree.php";
Braintree_Configuration::environment("sandbox");
Braintree_Configuration::merchantId("id");
Braintree_Configuration::publicKey("key");
Braintree_Configuration::privateKey("key");

$result = Braintree_Transaction::sale(
array(
'amount' =&gt; "100.00",
'merchantAccountId' =&gt; 'blue_ladders_store',
'creditCard' =&gt; array(
'number' =&gt; "378282246310005",
'cvv' =&gt; "1234",
'expirationDate' =&gt; "12/2017",
 ),
 'options' =&gt; array(
 'submitForSettlement' =&gt; true,
  'holdInEscrow' =&gt; true
   ),
  'serviceFeeAmount' =&gt;'1'

   )
   );`
</code></pre>

<p>This code is working fine for normal transaction because transactions are showing in my dashboard. But when releasing amount from escrow it showing 
"message: Cannot release a transaction that is not escrowed."
It means my transaction is not Escrow. Is it a problem of location? I am hitting the service from India. Any problem with the location.
Please help me for escrow. </p>
