SABnzbd Port Settings
One of the most common questions is: Which SABnzbd port should I use?
- Web Interface Port:
- Default: 8080
- SSL Web Interface: 9090
- Both can be changed in Config > General > Host/Port.
- Default: 8080
- Usenet Server Ports:
- 563 (SSL) – the standard secure Usenet port.
- 119 (non-SSL) – traditional but unencrypted.
- 80/443 – sometimes used to bypass ISP restrictions.
- 563 (SSL) – the standard secure Usenet port.
Most users should stick with port 563 (SSL) when configuring their provider for secure, encrypted downloads.

Adding NZBs
There are several ways to import NZBs:

Using Indexers
SABnzbd integrates with multiple NZB indexers via API keys. Adding more than one indexer ensures reliability if one goes offline.
For background on indexers and Usenet search, read our Usenet Search Guide.
RSS Feeds
You can configure RSS feeds inside SABnzbd to automatically fetch NZBs from your indexers. This lets you build automated pipelines.
Under ‘’security’’ section, set your access to Full API, and set a SABnzbd Username and Password for added security. This will prevent other people from being able to easily access your SABnzbd interface.
These settings should allow you to integrate with your chosen third party apps while ensuring maximum security.
Integration with 3rd-Party Apps
SABnzbd pairs seamlessly with automation tools such as:
- Sonarr

To enable integrations:
