Includes ARB only other like AIM, CIM, SIM and DPM are planned. I have moved the API code base to individual API files as the params and returns were was making it cumbersome.
Please feel free to use this as code base to enhance the extension, or even better release your own extension for AuthorizeNet gateway.
This release is not tested, has lot of attributes in the form and validation that are not defined. However, I have documented some for which you will have to define the validation rules, and define the attribute in authFormARB. Due to time constraint, all I could do is check that API response are received, and committed success with prior release of base code.
Yii 1.1.5 may work on other versions
For ARB create see modules.catalogs.VendorController Other operation like cancel, delete and update to be done
