We have a good working OS Commerce shop. We have just opened an Internet Merchant Account with HSBC. We installed and set up the Contribution for integrating OS Commerce with HSBC, however it does not work and returns an error when you try to checkout (The transaction failed because of invalid input data.).
The job is to get this working!
We can provide merchant ID, HASH Key and FTP access. The rest is up to you.
Please let me know if you have experience with this contribution or with this bank (HSBC)
