Dinesh..
I think the issue with people not finding the API key is this (I also almost wrote you about it, because I couldn’t find it too.).
In the email with subject [D Ness Car Key] Your username and password that you send us after the purchase, you give us a login link, which is this one: https://dineshkarki.com.np/wp-login.php
After loggin in however, we suddenly are inside your business website, in a subscriber role or something, and we can’t do anything, and start looking for our API key, but find nothing.
Instead of giving this https://dineshkarki.com.np/wp-login.php in that email, you should put this one in it: https://dineshkarki.com.np/checkout/manage-api-key because That one leads directly to our customer account, where we can find thr API key.
Hope that helps.
Kind regards,
Dirkje
