JavaScript API Latency Estimates

Merchants can estimate that API response latency for the Paze Merchant JavaScript Software Development Kit will roughly correspond to the following.

Note: The numbers below constitute estimates to be used for system design guidance and are subject to network latency and third-party services beyond Paze’s control. They do not represent a binding Service Level Agreement (SLA) or commitment by the Paze service.

JavaScript API Latency Estimates

API	Latency (estimated)	Comment
CanCheckout	5000ms	To validate wallet presence for given lookup key Note*: While unexpected, timeouts may possibly affect typical latency response times
Checkout	5000ms	To render appropriate wallet experience for consumers; may be affected by the time duration of a Consumer’s actions within the experience (i.e. enter OTP, select card, etc.) Note*: While unexpected, timeouts may possibly affect typical latency response times
Complete	3000ms	To retrieve required transaction data from card networks
