Applying Taxes with Payments REST API

[jshelto]

When creating a payment with the Payments REST API, if you do not pass a shipping address, it is possible for the customer to update their shipping address in the paypal pop-up window before completing their payment. If they do this, how can I execute a callback to my server to update the amount in taxes that they should be charged based on their updated shipping address? Ideally, they complete their purchase in the pop-up window without having to be redirected to a review page on my site.

Hi, in REST you first create the payment and then you need to call the execute method to execute it. In between you can call the

GET /v1/payments/payment/payment_id

to get the payment details and if the address is changed then you have 2 options:

1) before to call POST /v1/payments/payment/payment_id/execute call PATCH /v1/payments/payment/payment_id to amend the tax value.

2) when you call POST /v1/payments/payment/payment_id/execute, pass the "transaction" object with an amended tax value
