Introducing API v4: Simpler, more consistent, and built for what’s next

Fingerprint has launched API v4 to enhance its device intelligence capabilities, offering a more streamlined and consistent experience for developers. The update simplifies integrations by unifying data formats across core components like the Server API, Webhooks, Sealed Client Results, and JavaScript Agent, resulting in faster and more predictable implementations. Key improvements include fewer core endpoints, lighter payloads, modern authentication, and clearer error messages. The JavaScript Agent v4 also introduces features like Suspect Score access and built-in Visitor ID caching. The update aims to reduce long-term maintenance and facilitate future feature adoption, with a migration timeline in place and full support available for a year post-deprecation. The API v4 is currently live, with recommendations for early migration to maximize the benefits of new features and maintain accuracy.
