Currently the only features supported are:

• Creating Purchases
• Tokenizing Cards
• Purchasing with a tokenized card

Further support for additional functionality will be added as time permits, however if you require this funcitonality and are not able to add it yourself please contact [email protected] and request the changes.

Usage

Purchases

import fatzebra

gw = fatzebra.gateway.Gateway("your username", "your token", True) # The final param indicates whether or not to use the sandbox
try:
    result = gw.purchase(100, "Jim Smith", "5123456789012346", "05/2014", "123", "122.99.99.111")
    if result.successful:
        print "Purchase approved - ID: " + result.id
    else:
        print "Purchase declined. Message:  " + result.message
except fatzebra.errors.GatewayError, e:
    print "Gateway error: " + str(e.errors) # <-- e.errors is an array.
except fatzebra.errors.AuthenticationError:
    print "Authentication error - please check your username and token"

Tokenization

import fatzebra

gw = fatzebra.gateway.Gateway("your username", "your token", True) # The final param indicates whether or not to use the sandbox
try:
    card = gw.tokenize("Jim Smith", "5123456789012346", "05/2014", "123")
    print "Card Tokenized - token: " + card.token
except fatzebra.errors.GatewayError, e:
    print "Gateway error: " + str(e.errors) # <-- e.errors is an array.
except fatzebra.errors.AuthenticationError:
    print "Authentication error - please check your username and token"

Purchase with Token

import fatzebra

gw = fatzebra.gateway.Gateway("your username", "your token", True) # The final param indicates whether or not to use the sandbox
try:
 token = "abc12345"
 result = gw.purchase(100, token, "122.99.99.111")
 if result.successful:
     print "Purchase approved - ID: " + result.id
 else:
     print "Purchase declined. Message:  " + result.message
except fatzebra.errors.GatewayError, e:
 print "Gateway error: " + str(e.errors) # <-- e.errors is an array.
except fatzebra.errors.AuthenticationError:
 print "Authentication error - please check your username and token"

Refund

import fatzebra

gw = fatzebra.gateway.Gateway("your username", "your token", True) # The final param indicates whether or not to use the sandbox
try:
    original_transaction = "013-P-ABJU879H"
    result = gw.refund(original_transaction, 100, "my refund reference")
    if result.successful:
        print "Refund approved - ID: " + result.id
    else:
        print "Refund declined. Message:  " + result.message
except fatzebra.errors.GatewayError, e:
    print "Gateway error: " + str(e.errors) # <-- e.errors is an array.
except fatzebra.errors.AuthenticationError:
    print "Authentication error - please check your username and token"

Notes

The gateway class utilizes 3 error classes:

• fatzebra.errors.GatewayError - this represents an unsuccessful response from the gateway (invalid card number, expiry etc). Check the errors attribute for messages (array)
• fatzebra.errors.GatewayUnknownError - this represents an unknown error. Check the code and response attributes for details
• fatzebra.errors.AuthenticationError - this indicates your username and token are incorrect. Confirm that you have the right details and you are using the right gateway. Sandbox credentials will begin with TEST
