# Integrate with Talon.One

> Integrating with Talon.One revolves around two main concepts: sending customer session updates and processing rule effects.

> For the complete documentation index, see [llms.txt](https://docs.talon.one/llms.txt).

## Integration landscape

Any integration uses at least the [Integration API][Integration API] to send
business data to the Campaign Manager's Rule Engine. The Rule Engine is where
all promotion rules are processed.

The Rule Engine determines which rules should be applied based on the data it
receives. For every rule whose conditions are met, the engine returns the rule
[effects](/docs/dev/integration-api/api-effects.md) to the integration layer.
For example _the coupon code is valid_ or _apply a discount_.
