Integration of ING payments, inFakt, Faktownia with WHMCS

I need to make integrations for WHMCS with:

1. issuing Invoices - inFakt, Fakturownia, ImojeING ( your choice ).

2. making call back for przelewy24 plugin.

3. call back API integration for ING transfers

- Creation of automatic original invoice after posting funds in whmcs from pro forma.

- created invoice must have in service items fixed description (that is, our phrase service name) + downloaded domain name from whmcs pro form or after API from whmcs.

- Adding customers in WHMCS will add the customer in the selected invoice program

I ask for suggestions from those experienced in the topic, perhaps there are ready-made in your portfolios and php developers able to add a piece of code.
