API key
- Create an application key in the Backblaze console.
- Use the S3-compatible endpoint rather than the native B2 API; the S3 one works with standard tooling.
- The region is part of your endpoint host, for example s3.us-west-004.backblazeb2.com.

Worth knowing
- Two different APIs exist: the native B2 API and the S3-compatible one. Only the S3 one takes SigV4.
- The region label appears in the host and must match the key's region.
