Userflow API
Provides a REST API for managing user onboarding flows, checklists, and product tours server-side, allowing agents to identify users, update attributes, and track task completion without front-end instrumentation.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Single account-scoped API key with no scope restrictions. For agents, consider rotating keys after major pipeline changes. No IP allowlisting documented.
⚡ Reliability
Best When
You need to drive onboarding checklist state and user targeting from server-side business logic rather than purely relying on client-side event detection.
Avoid When
You have no client-side JavaScript integration capability — the server API manages data, but all visible in-app guidance still requires the browser SDK to render.
Use Cases
- • Identify and upsert user records in Userflow with attributes (plan, role, company) from your backend so in-app tours target the right audience segments
- • Mark checklist tasks as complete server-side when a user completes an action detected by your backend (e.g., first API key created) without requiring a client-side event
- • Programmatically start or dismiss a specific product tour for a user based on a lifecycle trigger from your CRM or support tool
- • Sync user attributes from an external data source on a schedule to keep Userflow segments current for tour targeting logic
- • Retrieve checklist completion state for a cohort of users to calculate onboarding funnel metrics in an external analytics tool
Not For
- • Rendering the actual in-app UI components (tooltips, modals) — those require the Userflow JavaScript SDK on the client side
- • A/B testing onboarding flows with statistical significance analysis (Userflow has basic testing but not a dedicated experimentation platform)
- • Customer support ticketing or live chat during onboarding
Interface
Authentication
API key passed as a Bearer token in the Authorization header. Keys are account-scoped and managed in the Userflow dashboard settings.
Pricing
Free tier is limited in flow count and MAU. API access is included on all plans.
Agent Metadata
Known Gotchas
- ⚠ Server-side API can update user attributes and mark tasks complete, but cannot trigger the visual rendering of tours — the JavaScript SDK must be present in the browser for any UI to appear
- ⚠ User IDs must be consistent between the server-side API calls and the client-side SDK identify calls; mismatches create duplicate user records
- ⚠ Checklist task completion via API bypasses Userflow's built-in event listeners, which means completion analytics in the Userflow dashboard may show manual completions differently
- ⚠ The API does not support bulk user operations — syncing large user sets requires looping individual upsert calls which can be slow at scale
- ⚠ Webhook event payload schemas are not versioned and have changed without notice in the past; agents consuming webhooks should handle unknown fields gracefully
