What is Instant Update API and how can it help my business?
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 Shipping Options. This gives buyers more accurate shipping options based on actual cart items and ship-to addresses. The feature also supports Flat-Rate Shipping Options and third-party shipping and tax calculation.
