How do I know if buyer paid with Venmo or PayPal?

[FQP]

I have buttons for both PayPal and Venmo on my website. When a user makes a purchase, the money always goes to my PayPal.

I want to know which one the buyer used to pay for a variety of reasons, is there a way to know? 

Sometimes it says Mobile Payment but that still doesnt help know if it was PP or Venmo

Thanks

Hello @FQP,

Welcome and Thank you for reaching out to us through PayPal Community Forum!

I understand your concern about the payment method. Please note, whenever you receive money through any payment method, you will be notified via email or text with the transaction details. If you have received payment via PayPal then we will notify you and vice versa for Venmo. Also
account activity will show the payments as linked to Venmo.

Regards,
Ayesha

"If you have received payment via PayPal then we will notify you and vice versa for Venmo"

That's not what happens for me.

I am using Jotform and there is an option for PayPal and Venmo on my form. No matter which one the buyer chooses, the payment comes through PayPal and I get no notifications from Venmo, despite everything working properly.

I just want to know the Venmo username of the buyer.
