Version info

Details

​

Synology Download Station

Questarr should work with both the legacy and modern Synology task APIs by querying SYNO.API.Info and using the best available task endpoint reported by the NAS. The legacy API is documented in Synology’s official Download Station API guide, while the newer SYNO.DownloadStation2.Task v2 API has been observed on DSM 7 era systems such as DSM 7.2.1 with Download Station 4.0.1.

​

Transmission

Questarr uses the long-lived Transmission RPC interface rather than targeting one exact Transmission release. Transmission 4.1.0 introduced JSON-RPC 2.0 support and snake_case RPC strings, so newer protocol changes should be checked before making stricter version claims.

​

qBittorrent

Questarr targets the qBittorrent WebUI API. Historical documentation exists for qBittorrent 3.2.0 through 4.0.4, while the maintained OpenAPI documentation covers the newer 4.1+ API family.

​

SABnzbd

Questarr supports SABnzbd through its HTTP API. The current API supports both addurl and multipart addfile flows, and modern releases such as 5.0.4 are in scope for this integration.

​

NZBGet

Questarr supports NZBGet through its RPC API, including the append method used to add NZB files, archives, or URLs to the queue. The official NZBGet API documentation states that it covers version 13.0 and later.
