Information about the SDK for payflow pro with SWIPE TRANSACTIONS I found how to add swipe parameters as follows

Where I posted information to originally:

I have looked for it in the documentation and search for it in the forums and on the web in general.

If it does, can someone point me to the documentation / thread where this information can be found.

2nd post

==========================

I started to look into it a little deeper, and started to look into the parameters I used in the PFPRO client 2.x.

I do not have a mag stripe reader with me, but I believe I ran a sample through the API https post and it appears it gave me a proper response (Declined).

I believe if it did not work, it would of gave me another error message, maybe something like "BAD PARAMETER" or "BAD NAME-VALUE PAIR".

I know it is not documented, but it does appear to work.

The code below was pulled from a website my associate found, It was originally developed in C sharp, C Pound, C#) But I redeveloped in into vb.net.

I believe the original c sharp code may have came from this website:

Here is information I found in a payflow implementation on the Wells Fargo site (of course i did not dig for it, google found it for me) .

Submitting Card-Present (SWIPE) Transactions

Payflow Pro supports card-present transactions (face-to-face purchases).

NOTE:SWIPE (card-present) transactions are not supported by the PayPal processor.

Follow these guidelines to take advantage of the lower card-present transaction rate: Contact your merchant account provider to ensure that they support card-present transactions. Contact PayPal Customer Service to request having your account set up properly for accepting and passing swipe data.

If you plan to process card-present as well as card-not-present transactions, set up two separate Payflow Pro accounts. Request that one account be set up for card-present transactions, and use it solely for that purpose. Use the other for card-not-present transactions. Using the wrong account may result in downgrades. A Sale is the preferred method to use for card-present transactions. Consult with your acquiring bank for recommendations on other methods.

Supported Processing Platforms

PayPalis certified to submit card-present transactions for the following processing platforms:

American Express Phoenix

First Data Merchant Services (FDMS) Nashville

First Data Merchant Services (FDMS) North

First Data Merchant Services (FDMS) South

Global Payments Central

Global Payments East

Nova

Paymentech New Hampshire

Paymentech Tampa

Card-present Transaction Syntax
Use the SWIPE parameter to pass the Track 1 or Track 2 data (the card’s magnetic stripe information). Include either Track 1 or Track 2 data—not both (up to 80 alphanumeric characters). If Track 1 is physically damaged, the POS application can send Track 2 data instead. The track data includes the disallowed = (equal sign) character. To enable you to use the data, the SWIPE parameter must include a length tag specifying the number of characters in the track data. For this reason, in addition to passing the track data, the POS application must count the characters in the track data and pass that number. Length tags are described in "Using Special Characters in Values" (see below -copied from page 25 in the adobe document). The length tag in the following example is [40]. Do not include the ACCT or EXPDATE parameters in card-present transactions, as this data is included in the SWIPE value.

Example Card-present Transaction Parameter String

This is an example card-present transaction parameter string:

"TRXTYPE=S&TENDER=C&PARTNER=PayPal&USER=SuperMerchant&PWD=SuperMerchant&SWIPE[40]=;4912000033330026=15121011000012345678?&AMT=21.00"

Using Special Characters in Values

Because the ampersand (& and equal sign (=) characters have special meanings in the PARMLIST, name-value pairs like the following examples are not valid:

NAME=Ruff & Johnson

COMMENT1=Level=5

To use special characters in the value of a name-value pair, use a length tag. The length tag specifies the exact number of characters and spaces that appear in the value. The following name-value pairs are valid:

NAME[14]=Ruff & Johnson

COMMENT1[7]=Level=5

NOTE:Quotation marks ("") are not allowed even if you use a length tag.

name value swipe
swipe and name and value and pairs
