If you want your customer to pay the fixed amount that you have set, the amount value must be greater than zero and "type" does not need to be defined.
However, if you want your customer to decide how much to pay, you can either set the amount to 0 or you must designate the type as either "preset" or "options" and set values to it.

type

string

enum

This parameter allows you to specify the preferred payment method for customers. If you want your customer to choose what to pay then you need to set the type to either "preset" or "options".

Allowed:

preset

If you’ve set the "type=preset" you can specify a minimum and maximum payment amount for your customers in this field and then they'll pay only within this range.
