Integration with KSeF (PHP class).

We have a working web service (PHP+MySQL), which has the ability to issue invoices, adjustments and bills. We are looking for a person to complete the integration with the KSEF system. We expect the contractor to provide a complete solution including transfer of rights. Ideally, the bidder should already have experience in integration with KSEF. Functionalities that should be taken into account:

- session establishment

- preparation of XML according to MF specifications

- sending an invoice

- receipt of UPO

- closing the session

This is, of course, the scheme, the details to be determined.

I invite you to make an offer to people who think about the execution of the order seriously and not for millions....

Edit. Transfer of rights in the form of a protocol with the source code.
