I am using [paypal\_adaptive](https://github.com/tc/paypal_adaptive) gem and having some problems.
This is my code in config/paypal\_adaptive.yml:

```
development:
  environment: "sandbox"
  username: "x@gmail.com"
  password: "xxx"
  signature: "xxx"
  application_id: "APP-80W284485P519543T"

test:
  environment: "sandbox"
  username: "x@gmail.com"
  password: "xxx"
  signature: "xxx"
  application_id: "APP-80W284485P519543T"

enviorment:
  environment: "sandbox"
  username: "x@gmail.com"
  password: "xxx"
  signature: "xxxx"
  application_id: "APP-80W284485P519543T"

```

of course the XXX is the real details. I also tried with the API credentials that were given me, didn't work either way.
Here's the controller code which controls the payment:

> 
> >
>  pay\_request = PaypalAdaptive::Request.new
> 
> 
> 

```
data = {
"returnUrl" => "http://localhost:3000/payments/completed_payment_request", 
"requestEnvelope" => {"errorLanguage" => "en_US"},
"currencyCode"=>"USD",  
"receiverList"=>{"receiver"=>[{"email"=>"xxx@gmail.com", "amount"=>"10.00"}]},
"cancelUrl"=>"http://localhost:3000/payments/canceled_payment_request",
"actionType"=>"PAY",
"ipnNotificationUrl"=>"http://localhost:3000/payments/ipn_notification"
}

@pay_response = pay_request.pay(data)

```

I am getting the following array (which contains the error) when trying to output pay\_response:

> 
> >
>  ["responseEnvelope", {"timestamp"=>"2011-05-03T12:00:54.107-07:00", "ack"=>"Failure", "correlationId"=>"242e1fc31cf18", "build"=>"1846084"}] ["error", [{"errorId"=>"560022", "domain"=>"PLATFORM", "subdomain"=>"Application", "severity"=>"Error", "category"=>"Application", "message"=>"The X-PAYPAL-APPLICATION-ID header contains an invalid value", "parameter"=>["X-PAYPAL-APPLICATION-ID"]}]]
>

I am really hopeless. Thanks in advance.
