Klaviyo is an email marketing service that allows companies to send targeted and transactional emails to their audiences.
The Klaviyo API allows developers to access and integrate the functionality of Klaviyo with other applications. Some example API methods include retrieving and managing events, managing account information, and retrieving analytics data about email marketing campaigns.
Six APIs were added to the ProgrammableWeb directory in categories including Recognition, Background, and Healthcare. Also added are several SDKs for email marketing firm Klaviyo, ecommerce service Whiplash, and one unofficial PHP SDK for the Marvel Comics API. Here's a rundown of the new additions.
