Userflow REST API

The Userflow REST API allows back-end applications to synchronize user data, track events, and manage groups or companies within the Userflow platform. It provides endpoints for creating, updating, and deleting users; listing and querying users with cursor-based pagination; posting custom events that trigger flow conditions; and managing group memberships. Authentication uses Bearer token API keys scoped per environment, configured under Settings in the Userflow dashboard. The API base URL is https://api.userflow.com and all payloads use JSON.
