I need an IPN / API system for my server. It need to do all basic transaction request and confirmation like paypal does. We have a website that have points system. and we sell stuff to customer with their points. and customer can aslo buy missing point from us. Other ecommerce site want to let our customer use their points from our website to buy stuff on the other ecommerce website. so I need to set my server like a paypal so it can receice request to transfer point from a customer account into the marchant account, with all the same standard variable that paypal ask. Every transaction are recorded on our database, and need to do the similar as paypal with creating an unique transaction id, that will be register into the database. as right now user can log on our site and see all transaction they made with their points so it need to be added in the transaction table. like: IPN Messages Generated by ourserver Payments Standard with all the standart variable see below in the ipnguide from paypal page 15. We also need our server to be able to send ipn back to an ipn listener so like paypal we need to have the option so merchant send notify_url. Iwill send our point system plugin to the awarded bid. Our system work on Wordpress. for any question please message me,

Dear Sir, If I am not wrong, you just need a basic virtual payment/transaction server where currency is POINTs and the request/response structure is similar to PayPal. Is that correct? If so, even if your website runs on WordPress, I think I can develop a minimal set for you with pure PHP/MySQL that acts this way as well as logging all the happening transaction to your existing site's transaction table. a. Partner site redirects/puts the user on your server's landing page; b. Your server's landing page collects all the information from the user; c. Optionally, your server throws response to the partner site as PayPal IPN does; d. Upon completion, your server redirects the user back to the partner site's specific page depending on success/failure; e. _POST & _REQUEST variables are to be named following PayPal convention; I hope you will find me eligible for the job.

Hi, I have written several APIs and I'm well versed in Paypal's API (both RESTful and SOAP). I understand exactly what you're trying to accomplish as far as creating an API system on your site where users can make purchases from third party vendors who are also members of your site using the site's point system as a sort of currency for the exchange. I have a few question however... Paypal has two different versions of their API, a SOAP version and RESTful version. I'm assuming your looking for a RESTful API which is the classic Paypal API. Which style of API do you need implemented? Do you need all the exact same API calls as Paypal? You might not have use for some of them like mass pay or subscriptions. I'm guessing you only need the basic Paypal operations. Does your API also need to keep track of the shipping information and other purchase order details? Or simply the basic transaction details. Is the plugin you mentioned a custom built plugin or one you downloaded? There are likely more questions that should be asked but I'll try not burden you with too many of them right now. I just want to get an exact understanding of your project needs in order to give you the most accurate bid possible. If you have any questions for me or if you would like to discuss the project further please let me know. Thanks for taking the time to read my proposal. Regards, Derek

I have extensive experiance in developing transaction processing systems for the financial services industry. Previous projects I have worked on include: Rule based transaction processing system, Interfacing with Paypal, Cheque truncation systems etc. It would be my pleasure to add value to your project. Regards. Note: I have included an overview of an I application I developed on a previous assignment. Qurion Transaction Manager (QTM) is a “rule based” transaction processing engine. In QTM, transactions are received through various channels and are processed according to user defined rules. A simple application of such rule based processing is having QTM initiate a voice call back to the customer requesting confirmation of a cheque. A more interesting application of QTM is as a transaction processing hub, providing a unified view of all the critical aspects of transaction processing across the network. In such a scenario, QTM can also function as an intelligent transactions router, validating, processing, and then dispatching transactions to internal or external systems based on user defined criteria (eg: time, transaction type or traffic load etc). In fact QTM can be deployed as a transaction firewall, filtering what transactions get sent to certain locations. Are you in need of real time notifications on “suspicious” transactions? Or you have ever wanted to stream live “copies” of transactions to a remote DR site during “normal” processing?
