# Release a business rule

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


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

Releases the draft version of a business rule. The draft is promoted to the next version number and becomes the released version that Chargebee evaluates, so `latest_version` is incremented and `released_at` is set. Until you release it, the previously released version stays in effect.

Use this operation to promote a revision you staged with [Update a business rule draft](/docs/api/business_rules/update-a-business-rule-draft).

### Prerequisites & Constraints

The rule must have a draft, created by [Update a business rule draft](/docs/api/business_rules/update-a-business-rule-draft).

### Impacts

**

Business rule

**

The draft becomes the released version of the rule, `latest_version` is incremented, and `released_at` and `released_by` are set. The rule no longer has a draft, and Chargebee starts evaluating the newly released version in place of the previous one. Releasing does not change `active`, so a rule that has not been activated is still not evaluated.

Every release is a new version, and each [business ruleset](/docs/api/business_rulesets) that contains the rule picks up the newly released version, because a ruleset always evaluates the latest released version of its member rules.

### Implementation Notes

Review the version you are about to publish with [Retrieve a business rule draft](/docs/api/business_rules/retrieve-a-business-rule-draft) before calling this operation, because releasing cannot be undone and the change takes effect immediately for every ruleset that contains the rule.
