We are integrating PayJunction into our POS software. We need someone that can write (in VB.NET) a method to submit the transaction using the formats and include a webhook that is based on the local machine.
Please see PayJunction's API Documentation for more information: [url removed, login to view]
EDIT: In VB.NET, we will need to submit the request in JSON. Examples of the JSON requests can be found in PayJunction's API Documentation at the link above.
Contact me. I can help you. I also have experience in working on a similar application. I can get it done before deadline. Let me know if you need any help?
