Paypal API CALL

[extream2020]

Hi, i would like to connect the paypal api from my website to paypal so i can receive payments. The website is requesting me these things:

Setup

• Copy and paste the API username, password, and signature into the /.env file.
• Open and edit the /.env file by providing your keys like this:

CopyPAYPAL_MODE=sandbox
PAYPAL_USERNAME=yourPayPal@address
PAYPAL_PASSWORD=YourPassword
PAYPAL_SIGNATURE=YourSignatrue

• You have to use PAYPAL_MODE=live in your live server.

I cannot find where to do this, can someone help?
