## Overview

LINE Developers [https://developers.line.biz/](https://developers.line.biz/zh-hant/) It is a technical console provided by LINE, specifically for configuring development-related features for LINE Official Accounts. Here, you can configure various development resources, such as auto-push notification settings or authentication information when new users join, etc. This is different from LINE Official Account Manager, which is specifically used to manage real-time interactions and message exchanges with users.

## Frequently Asked Questions

### From the “Settings” section of LINE Official Account Manager (LINE OA), go to “Messaging API,” then click “LINE Developers,” but you can’t see the required data page?

If, after following the steps above and logging into your LINE account, you see a screen that is different from what you expected, it may be because you do not have the admin (Admin) permissions for the Provider and Messaging API Channel of that LINE account. First, please confirm with colleagues in your company whether someone has already created the Messaging API Channel. If you cannot find who created it or need more permissions, we recommend that you contact LINE Official Customer Support directly for assistance in recovering or adjusting the account permissions.

### Can’t find the existing channel; can I create a new one?

No. Each LINE Official Account corresponds to only one Messaging API Channel, so you cannot recreate it. If you cannot find the corresponding Messaging API Channel or Provider permissions, please contact LINE Official Customer Support promptly for help recovering the relevant account permissions.
