Braintree payments Escrow Funding - php

Question

I am trying to implement escrow funding using braintree in php. I have downloaded library from here. My code is below:-
require_once "../braintree/lib/Braintree.php";
Braintree_Configuration::environment("sandbox");
Braintree_Configuration::merchantId("was4zgn5x6vt99h");
Braintree_Configuration::publicKey("ydjrasdwyw9npkvnw4");
Braintree_Configuration::privateKey("f197ac5a66a1fsad37d3950890b2cbda9");
$result = Braintree_Transaction::sale(
array(
'amount' => "100.00",
'creditCard' => array(
'number' => "4111111111111111",
'expirationDate' => "12/2014",
),
'options' => array(
'submitForSettlement' => true,
'holdInEscrow' => true,
)
)
);
echo "<pre>";
print_r("\n message: " . $result->message);
It is working for direct payment. But It is not working for escrow. Please check my code.
Error is:-
"message: Transaction could not be held in escrow."
I have got the code from here

Answer 1

At last i got the actual answer from Braintree. I had to add two more parameters. One merchantAccountId and other is serviceFeeAmount. Here merchantAccountId id is actually sub merchant merchantAccountId. You will get merchantAccountId from Braintree. After logging in, go to settings->Processing. At the bottom of the page you will get View All Merchant Account. Here you will get merchantAccountId. Don't use default merchantAccountId it will not work.
require_once "../braintree/lib/Braintree.php";
Braintree_Configuration::environment("sandbox");
Braintree_Configuration::merchantId("was4zgn5x6vt99h");
Braintree_Configuration::publicKey("ydjrasdwyw9npkvnw4");
Braintree_Configuration::privateKey("f197ac5a66a1fsad37d3950890b2cbda9");
$result = Braintree_Transaction::sale(
array(
'amount' => "100.00",
'merchantAccountId' => 'test_user_instant_5vcgn574',
'creditCard' => array(
'number' => "4111111111111111",
'expirationDate' => "12/2014",
),
'options' => array(
'submitForSettlement' => true,
'holdInEscrow' => true,
),
'serviceFeeAmount' =>'1'
)
);
echo "<pre>";
print_r("\n message: " . $result->message);

Answer 2

I think that you need two things:
Pass a merchant_account_id - see example on https://www.braintreepayments.com/docs/php/transactions/escrow
You can only do escrow if your merchant account is using Marketplace. https://www.braintreepayments.com/docs/php/guide/marketplace

Answer 3

I think you made a mistake in your code:
'options' => array(
'submitForSettlement' => true,
'holdInEscrow' => true,
)
Should be:
'holdInEscrow' => true
There should be no comma after 'holdInEscrow' => true
