This integration method is NOT recommended if you have not previously integrated similar payment solutions that require activation. Recommended integration method

When choosing integration via API, we recommend that you additionally make the following improvements:

1. Add hints in text form for each payment system (PS) to explain to a user all payment steps.
2. Add a visual explanation of the payment process - gifs showing the process and screenshots of the payment steps.
3. Screenshots and all the necessary minimum text information can be obtained directly from Paykassma TS.
