2.2 Transaction Type

At the time of writing, only SALES transaction type is implemented in ADempiere 3.5.3a, here is an extraction from the source code(..base/src/org/compiere/model/PP_PayFlowPro.java)

   public boolean processCC () throws IllegalArgumentException
   {
   log.fine(p_mpp.getHostAddress() + " " + p_mpp.getHostPort() + ", Timeout=" + getTimeout() + "; Proxy=" + p_mpp.getProxyAddress() + " " + p_mpp.getProxyPort() + " " + p_mpp.getProxyLogon() + " " + p_mpp.getProxyPassword());
   //
   StringBuffer param = new StringBuffer();
   // Transaction Type
   if (p_mp.getTrxType().equals(MPayment.TRXTYPE_Sales))
   param.append("TRXTYPE=").append(p_mp.getTrxType());
   else
   throw new IllegalArgumentException("PP_PayFlowPro TrxType not supported - " + p_mp.getTrxType());
   // Mandatory Fields
   param.append("&TENDER=C") // CreditCard
   .append("&ACCT=").append(MPaymentValidate.checkNumeric(p_mp.getCreditCardNumber())); // CreditCard No
   param.append("&EXPDATE="); // ExpNo
   String month = String.valueOf(p_mp.getCreditCardExpMM());
   if (month.length() == 1)
   param.append("0");
   param.append(month);
   int expYY = p_mp.getCreditCardExpYY();
   if (expYY > 2000)
   expYY -= 2000;
   String year = String.valueOf(expYY);
   if (year.length() == 1)
   param.append("0");
   param.append(year);
   param.append("&AMT=").append(p_mp.getPayAmt()); // Amount

3. Common Test Cases

If you have opened your account to process American Express (AMEX), one dummy account for testing is 378282246310005 using 0000 as Verification Code. Also note that the PayPal sandbox treats all amount as US Dollar and will not process any single transaction exceeding $1,000.
