Parameters in the panel
| Field | Value |
|---|---|
| Endpoint | https://s3.REGION.backblazeb2.com (e.g. s3.us-west-004.backblazeb2.com) |

Access keys
From Application Keys create a read-only key limited to the bucket. keyID is the access key, applicationKey is the secret (shown only once). Keys with S3 access are needed.
The gateway only reads: permission to read objects (s3:GetObject) on the bucket or folder is enough. → S3 buckets
Things to watch
- The endpoint is found in the bucket details: it depends on where the bucket was created.
- B2 requires v4 signatures (v2 is not supported); the region is part of the signature, so it must match the endpoint's.
Known issues
None emerged from the documentation; however we could not test it live.
