Hello team, thank you for your help,
Yes Nishit we have got many functionalities already done and just need to link them all together to a customer request. As per paypal it is also done on the site you are right, we just need this settings brought up to admin front end as advised earlier so admins could change their paypal credentials when needed. Currently it is back ended and we do not want admin to search for a source code to change their paypal secrets.
As Mark mentioned just repeating again – we know it is new for you and we not pushing you with this please take time and do not rush.
