J2Pay

version 2.9.11

J2Pay is an open source multi-gateway payment processing library for Java. Which provides simple and generic api for many gateways. It reduces developers efforts of writing individual code for each gateway. It provides flexibility to write code once for all gateways. It also excludes the efforts of reading docs for individual gateways.

Whats new in 2.7.8

J2pay now supports Authorize and Capture transactions. Below is the list of all the transaction types supported now.

1. Authorize
2. Capture
3. Purchase (Authorize + Capture in one step)
4. Refund
5. Recurring
6. Void

Why use J2Pay

1. You want multi gateway support in your application.
2. You do not have time for learning individual payment gateways docs that are also (poorly documented).
3. You want to support multiple payment gateways in your application without worrying about the implemention of each gateways.
4. You want to use single api for each gateway.
5. You dont want to write seperate logic for each gateway.

Generic Request/Response.

If you would like to work with multiple gateways the main problem developers usually face are api prameters names.

for example.

some gateways take first name as fname or first_name or take card number as CardNumber or Card_Number or card.

J2Pay excludes this type of efforts and provide classes for customer details and customer cards which will remain same for all gateways.

Same problem when parsing gateway response.

J2Pay also excluded this type of efforts and provide generic response for all gateways.

for example.

when a transaction is successfully processed some gateways return transaction id as transaction_id or transId or trans_tag blah blah. but if you are using J2pay you will always receive "transactionId".

Documentaion

You can find documention inside docs directory, documentation is build on php so you must host it.

The following gateways are available.

Note if your desired gateway is not in list you are free to create an issue and we will integrate that gateway for you. or you can also write us at [email protected]
