I have read almost everything there is on the Internet (almost no examples) and studied the (very limited and confusing) documentation. I have a client were I am integrating payone, and I am not getting any further.
So I used the API client documentation and integrated the iframe client api example with creditcardcheck on page 35 (chapter 3.1.5.5). This works fine I receive the answer and a pseudocardpan.
As explained in the quick start guide, I then start the "preauthorization", using the server api with the pseudocardpan. I send all the necessary parameters again, and I end up on the server payone with status = approved .
I assume this is then successfull. However, what or how should I proceed? What is the transactionUrl for? Maybe someone has experience with payone.
