What is Instant Update API and how can it help my business?

 PayPal Instant Update API is a feature of Express Checkout that lets customers view postage options, insurance choices and tax totals at the beginning of the checkout process.

Studies show that buyers are more likely to complete checkout when more transaction details appear sooner and when there are fewer steps in the overall process. By providing important transaction details up front, Instant Update API makes checkout faster and simpler – two factors proven to boost customer sales.

Instant Update API supports Real-Time Postage Options. This gives buyers more accurate postage options based on actual cart items and send-to addresses. The feature also supports Flat-Rate Postage Options and third-party postage and tax calculation.

To get started using Instant Update API, contact your developer/cart partner or visit PayPal Developer Central to learn more.
