For PayPal gateway setup,
Query: Currently PayPal payment process going on client ID and secret code. If we can create PayPal gateway setup https://ibb.co/pdsK4Ry with new field(API username, API password, API signature) so it will change all PayPal payment code. So it is better we use current field(client id and secret code) that admin could change easily.
Can you please suggest what we do?
