I want to validate if given email address is exists in paypal? I need to verify if the paypal email they provided me exists or not? - paypal

Question

I want to give payments to my customers, for that purpose I am getting their email, I want to verify is that email address exists in paypal or not!
I searched and found payment identity API which I tried but that only provides me my data! Here is the LINK of that API.
I have also found Adaptive payment get verified status API but it is depreciated. Here is its Link.
Also found this link https://www.paypal.com/us/verified/pal=emailaddress to verify, but it doesn't work also! I got it from paypal Community Question.
Anyone here who can help me out this issue! Or if any one can help me in Connect With Paypal I am stuck on 6th step! This would also be used!

Answer 1

This is generally an unnecessary thing to implement.
But if you really must have this feature, you can indeed use Connect with PayPal, formerly known as Log in with PayPal).
Your question mentions being stuck but does not provide any technical detail about your problem or what you have tried so far.

Answer 2

If you have the paypal user's email address, you could check if there is a Paypal avatar associated with it, if not, it's not a valid paypal email account.
With the AvatarAPI service, using the "Paypal" provider, you send a HTTP post to https://avatarapi.com/v2/api.aspx request of
{
"username" : "##username##",
"password" : "###password##",
"email" : "#PAYPAL-EMAIL-ADDRESS##",
"provider" : "Paypal"
}
and if you get a response such as
{
"Name": "Whatever Company Ltd",
"Image": "https://pics.paypal.com/00/s/YTUwMmE3NDMtNDQ5Yi00ZDEyLThmZDktYmZmOTI0ZjM0Njcw/file_26.PNG",
"Valid": true,
"City": "",
"Country": "",
"IsDefault": true
}
then it's valid, or this if it's invalid:
{
"success": false,
"error": "Nothing found"
}
