I'm excited to use this library. However when doing composer update I get this error:

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - tuurbo/spreedly 0.9.2 requires guzzlehttp/guzzle ~4.0 -> no matching package found.
    - tuurbo/spreedly 0.9.1 requires guzzlehttp/guzzle ~4.0 -> no matching package found.
    - tuurbo/spreedly 0.9.0 requires guzzlehttp/guzzle ~4.0 -> no matching package found.
    - Installation request for tuurbo/spreedly ~0.9 -> satisfiable by tuurbo/spreedly[0.9.0, 0.9.1, 0.9.2].

Before finding this library I was hitting spreedly with guzzle directly, and using Guzzle 5.2. Is there a way I can overwrite your requirement of an old version of Guzzle? Or, is that even the problem.

I am trying to create a Spreedly client using:

// Retrieve transaction from POST data
$xmlText = file_get_contents('php://input', 'r');
$xml = new SimpleXMLElement($xmlText, LIBXML_NONET | LIBXML_NOCDATA);
// We expect only one transaction
$transactionXml = $xml->children()[0];

$client = new \Tuurbo\Spreedly\Client(new \GuzzleHttp\Client, []);
$client->setResponse($transactionXml);

Problem I have is that when response is set that way, status of the response does not get set on the client. Therefore the result of $client->success() and $client->fails() is always false.

I think it would be better if the code that sets the status:

if (isset($this->response['error']) || (isset($this->response['succeeded']) && $this->response['succeeded'] == 'false'))
{
    $this->status = 'error';

    return $this;
}

$this->status = 'success';

was inside setResponse method.

Should I PR?

According to Spreedly guide:

Note: Worldpay uses postMessages to notify when authentication needs to progress to the next step. We pass these parameters in event.context.

{"MessageType": "profile.completed", "SessionId": "d3197c02-6f63-4ab2-801c-83633d097e32","Status": true)

These parameters should be included in the complete call using the key context.

{context: {"MessageType": "profile.completed", "SessionId": "d3197c02-6f63-4ab2-801c-83633d097e32", "Status": true}}

These parameters will only be sent during trigger-completion events

Would it be possible to allow to pass an array $data in the complete() call (it could be empty by default)?

    /**
     * Can be used to Completes a 3DS 2 transaction in the device fingerprint stage
     * See docs for more information.
     *
     * <code>
     *		// Completes a 3DS 2 transaction in the device fingerprint stage.
     *		Spreedly::transaction($transactionToken)->complete($data);
     * </code>
     *
     *
     * @return mixed
     *
     * @throws Exceptions\MissingTransactionTokenException
     */
    public function complete(array $data = [])
    {
        if (!$this->transactionToken) {
            throw new Exceptions\MissingTransactionTokenException();
        }

        return $this->client->post('v1/transactions/'.$this->transactionToken.'/complete.json', $data);
    }

You should not be doing times on the amount. Because the currency cannot always be split into 100.

For example YPN (japanese) will not be multiplied with 100.

For the new general credit method, the error is this:

Amount should be specified as an integer value corresponding to the number of cents. Example: $42.34 is 4234 cents.

I assume that the other methods are doing this for me, but not general_credit

A new endpoint transactions/{token}/complete has been added to be able to complete a
3DS 2 transaction (https://docs.spreedly.com/reference/api/v1/transactions/). The SDK cannot reach that endpoint right now so a new method like the one below should be added to src/Transaction.php

    /**
     * Can be used to Completes a 3DS 2 transaction in the device fingerprint stage
     * See docs for more information.
     *
     * <code>
     *		// Completes a 3DS 2 transaction in the device fingerprint stage.
     *		Spreedly::transaction($transactionToken)->complete();
     * </code>
     *
     *
     * @return mixed
     *
     * @throws Exceptions\MissingTransactionTokenException
     */
    public function complete()
    {
        if (!$this->transactionToken) {
            throw new Exceptions\MissingTransactionTokenException();
        }

        return $this->client->post('v1/transactions/'.$this->transactionToken.'/complete.json');
    }

Does this library support a general credit? One that follows this: https://docs.spreedly.com/reference/api/v1/gateways/general-credit/

Thank you,
Daniel

I am thinking use tuurbo/spreedly in laravel 5.1 but i don't know if is compatible, is it?

We need the ability to change the base URL with a config. This is because we need to route our spreedly calls through another service first then do some mappings and let that other service then forward to spreedly.

If I submit a PR which would allow overriding the Base spreedly URL (but still defaulting to the correct url) would that be something you would approve or is this something you'd rather me maintain in a separate fork?

In Client model.

For instance, if $this->response['payment_method'] is not set, then paymentToken() throws an exception, but response('payment_method.token') correctly returns null.

Is this expected behaviour? Should paymentToken not be wrapping a call to response(), rather than accessing the attribute directly?

In the Client::request() method you are checking for certain error codes and throwing exceptions when they occur, but if it's not one you check for, you just set $this->status = 'error' so that user's of the library must check for this variable every single time we make a request.

Code: https://github.com/tuurbo/spreedly/blob/master/src/Client.php#L82

Are you opposed to always throwing an exception on line 82? If you are, would you be opposed to adding a configuration variable we could set to throw exceptions (that's disabled by default)? I can write the code if you like.

We've seen Spreedly APIs returning HTTP 504 and other error response codes that aren't currently throwing an exception so our code just keeps chugging along.

What is the max allowed timeout in the setup?

According to Spreedly we need to set it to 64 seconds to be safe. https://docs.spreedly.com/reference/api/old/timeouts/

$client = new \Tuurbo\Spreedly\Client(new \GuzzleHttp\Client, []);

checkout_form is a CDATA field and $client->response('checkout_form') returns empty string.

This is because default Guzzle config doesn't set LIBXML_NOCDATA flag for SimpleXMLElement. See: http://php.net/manual/en/libxml.constants.php#constant.libxml-nocdata
