# Messaging API SDKs

LINE 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 different programming languages.

# Official SDKs

# LINE OpenAPI

LINE OpenAPI is a set of API interfaces provided by the LINE Platform, such as the Messaging API and LIFF server API, defined according to the OpenAPI specification. By using code generators such as OpenAPI Generator (opens new window) and Swagger Codegen (opens new window), you can easily use the features provided by the LINE Platform even in programming languages for which no SDK is provided.
