# Adds hosted relink flow for Financial Connections

## What’s new

Adds the ability to configure a [hosted relink flow](https://docs.stripe.com/financial-connections/relink/hosted.md#api-integration) when creating a [Financial Connections Session](https://docs.stripe.com/api/financial_connections/sessions/create.md?api-version=2026-03-25.preview). Previously, you could only configure a hosted relink flow through the Stripe Dashboard.

## Impact

This API offers more flexibility in processing high volumes of accounts, and allows you to customize emails or notifications by providing a link to the hosted page.

To request access to this preview feature, [email us](mailto:financial-connections-beta+hosted-relink-api@stripe.com).
