title: Backblaze B2 Native Application Keys API
description: The Backblaze B2 Native API provides programmatic access to Backblaze B2 Cloud Storage. It covers account authorization, bucket management, file upload and download, lifecycle rules, application key management, large file handling, replication, and event notifications. The API uses HTTPS with JSON request and response bodies. Authentication is performed via the b2_authorize_account endpoint which returns an authorization token used for subsequent calls.
