How to update existing Paypal account in Braintree?

Question

I want to update existing paypalAccount of a Vault user every time she makes a purchase using paypal checkout.

According to the documentation, I can only update creditCards using paymentMethodNonce.

Another piece of documentation shows how to update Paypal account using token. My understanding is that token is only available only after paymentMethod is added to Vault.

But all I know at this point (before I update the Vault) is paymentMethodNonce from the client-side. And I don't want to create a new paymentMethod/paypalAccount but to update the existing one.

Is there any way that I can update existing paypalAccount using paymentMethodNonce?

_{Full disclosure: I work at Braintree. If you have any further questions, feel free to contact support.}

Currently there is not a way to update a paypalAccount using a paymentMethodNonce.

You can update a paypalAccount by updating the paymentMethod tied to the paypalAccount. First, save a mapping from user to a payment_method_token on your server. The payment_method_token will be returned from paymentMethod.create. Then, anytime you want to update a user's details, you can retrieve the paymentMethod using the token, and call paymentMethod.update.
