# Messaging API SDKs

Our Messaging API SDKs include libraries, tools, and samples to make it easier for you to start developing bot apps with the Messaging API. Both the official SDKs and community SDKs are open-sourced and available in a variety of different programming languages.

# Official SDKs

LINE official SDKs for the Messaging API.

# Community SDKs and libraries

Our community SDKs and libraries are developed by third party developers and are available under general open source licenses. While LINE conducts limited reviews on the community SDKs, LINE does not provide official support or guarantees for these SDKs. See the applicable licenses and disclaimers for each SDK.

If you would like to share your SDK or library on this page, see the Community contribution guidelines and our Community Program Agreement (opens new window).
