Merchant
========
This is a credit card processing library. I needed this for [airflowing](http://airflowing.com/) an application from [flowing](http://flowingconcept.com/).
I've only needed to use [AprovaFacil](http://www.cobrebem.com.br/aprovafacil.html) so let me know if you want to support another gateway (there is a skeleton for [this one](https://www.braintreepayments.com/))
###Loading
Use this snippet to load it into your [Pharo](http://www.pharo-project.org/home)* 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
