Merchant

This is a credit card processing library. I needed this for airflowing an application from flowing.

I've only needed to use AprovaFacil so let me know if you want to support another gateway (there is a skeleton for this one)

###Loading

Use this snippet to load it into your Pharo* image:

Gofer it 
	smalltalkhubUser: 'Pharo'
	project: 'MetaRepoForPharo30'; 
	package: 'ConfigurationOfMerchant';
	load.

(Smalltalk at: #ConfigurationOfMerchant) load

###Example

gateway := MERAprovaFacilGateway new
				merchantUsername: merchantUsername;
				beProduction;
				yourself. 

Having the credit card and order objects allows you to do something like this:

gateway purchase: anOrder andStore: aCreditCard.

Which will make Merchant to actually not store credit cards on your servers but the token given by your gateway so you can later make a capture to take the money using:

gateway capture: anOrder token: aToken.

After that doIt, if authorised, you are 'anOrder value' richer*

Performing a doIt in a Smalltalk workspace never felt so good :)

*okay, minus costs

The rest is a couple of additional commands and protocol and handling errors elegantly

Have a happy business :D

###Contributions

...are welcomed, send that push request and hopefully we can review it together

###*Pharo Smalltalk Getting a fresh Pharo Smalltalk image and its virtual machine is as easy as running in your terminal:

wget -O- get.pharo.org/30+vm | bash
