I need to use paypal credentials (username, password, signature) for my magento2 store.
For credentials, I logged in to my paypal business account (provided by my client) and then navigate to Tools > All Tools > API Credentials and then click "Grant API permissions" under Pre-built payment solution. After click, it ask me for Add New Third Party Permissions link
It returns me Please enter valid API username. exception when I enter the user ID from Profile and Settings > My account settings > Manage users
Also the user ID I'm using prompts this message "For compliance reasons, we need to verify the identity of this user. Confirm identity" link.
Is it the issue because my user is not confirmed? Or should I need to add some other "Third Party Permission username" ?
