[1Flow](https://1flow.app/) enables product-led customer everboarding through embedded onboarding checklists, contextual guides, and empty states. Customers can get set up at their own speed, track progress, and collaborate across their team.

## Considerations

- This integration is only available for customers who have paid plans with both 1Flow and Amplitude.
- You must enable this integration for each Amplitude project you want to use it in.
- To use this integration, you must have an Amplitude User ID that maps to a 1Flow user profile. 1Flow supports the User ID field, so use the same User IDs across 1Flow and Amplitude.

## Set up the integration
