# Update an AI label rule

Source: https://docs.emelia.io/docs/inbox-api/update-ai-label-rule

Guide: [Inbox API](https://docs.emelia.io/docs/inbox-api.md)

`PATCH https://api.emelia.io/inbox/api/v1/ai-label-rules/{ruleId}`

Renames or recolors the label, changes the condition, configures auto-draft, auto-reply and `hideFromInbox`. All fields are optional but at least one is required. In Emelia, AI features are paid with Emelia credits: each incoming email classified while the workspace has at least one rule, and each auto-draft, is debited from the Emelia account. Setting `autoDraftEnabled` or `autoReplyEnabled` to true never returns `402 PLAN_REQUIRED` in Emelia.

## Authentication

Send your API key in the `Authorization` header: `Authorization: <your API key>`.
