# Activate a business rule

> For the complete machine-readable documentation index, see [llms.txt](https://apidocs.chargebee.com/llms.txt).


[Idempotency Supported](/docs/api/idempotency)

Activates a business rule by setting its `active` attribute to `true`, so that Chargebee evaluates it.

Every rule is created inactive, so this is the operation that puts a new rule into effect.

### Impacts

**

Business rule

**

The rule `active` attribute is set to `true`. Chargebee evaluates the version in `latest_version`, both when the rule is applied directly and when it is reached through a [business ruleset](/docs/api/business_rulesets) that contains it.

Nothing is released. If the rule has a draft, that draft stays unreleased and the version in `latest_version` remains the one evaluated.
