[Talon.One](https://hubs.li/Q01k6xNt0) is a promotion engine that lets you create targeted marketing promotions built around your customer and session data. Create, manage, and track discounts, coupon codes, referrals, loyalty, and product bundles in one platform.

The Talon.One integration lets you send audiences from Amplitude to Talon.One to create more personalized promotional campaigns.

## Considerations

- User update rate is 1000 users per minute. For example, if cohort size is 100,000 users, it takes 100 minutes to send all the user data to Talon.One.
- To use this integration, you must have an Amplitude User ID that maps to a Talon.One [Customer Profile ID](https://hubs.li/Q01kd4vg0). Talon.One supports any Customer Profile ID, for example:
  - Email
  - Phone Number
  - IDFA - Apple Ads ID
  - GAID - Google Ads ID

## Set up the integration
