## Legacy API — sunsets June 1, 2027

This page documents the original mailfloss API, which is being retired on **June 1, 2027**. New integrations should use the [v1 API](https://developers.mailfloss.com/quickstart).
:::

The integration settings API is used to modify the settings of connected email service providers associated with your mailfloss account. The integration settings API lets you programmatically change the integrations' settings, including adding blacklist/whitelist items, and in the future changing the action, frequency, and aggressiveness options.

For Authentication, Rate Limits, Response Headers, and Response Codes, please refer to these sections in the [Email Verification API](https://developers.mailfloss.com/email-verification-overview).

## The integration settings API is in beta

The API is currently in beta and under active development. While we'll make every effort to maintain consistency, updates may contain breaking changes.
