Every IPTV provider sends you login credentials in one of two formats: an M3U URL or Xtream Codes API credentials. They both deliver the same channels, but they work differently under the hood. Here is the plain-English breakdown so you can pick the right one.
What is an M3U URL?
An M3U URL is a plain-text playlist file hosted on the provider server. When you paste the URL into your IPTV app, the app downloads the file, which contains the list of every channel and its stream URL. Example:
http://server.example.com/get.php?username=USER&password=PASS&type=m3u_plus
The M3U URL itself contains your username and password as query parameters.
What is the Xtream Codes API?
Xtream Codes is a more modern protocol that exposes a full API. Instead of one big playlist file, the IPTV app talks to a server endpoint, requests the channel list, EPG, VOD library, and series, and gets each as separate, structured data. Example credentials:
Server URL: http://server.example.com:80 Username: yourusername Password: yourpassword
M3U URL — pros and cons
Pros:
- Universal — works in every IPTV app and player, including VLC, Kodi, Smart IPTV, and basic players.
- Simple — one URL, paste, done.
- Easy to share between devices.
Cons:
- EPG is not included by default — you usually need a separate XMLTV URL.
- VOD and series may not load in some players.
- Slightly slower channel list refresh on big lineups (40,000+ channels).
Xtream Codes API — pros and cons
Pros:
- Faster channel switching and lineup loading.
- EPG, VOD, and series are pulled automatically with one login.
- More efficient on bandwidth — only loads what you click.
- Better metadata (movie posters, series episodes, descriptions).
Cons:
- Not every IPTV app supports it — VLC and basic Smart IPTV apps do not.
- Requires three fields instead of one.
Which one should you use?
Use Xtream Codes API if: your app is IPTV Smarters Pro, Tivimate, OTT Navigator, GSE Smart IPTV, or any modern IPTV player. You will get a faster, smoother experience with EPG and VOD baked in.
Use M3U URL if: your app only supports playlists (Smart IPTV on Samsung/LG, VLC, Kodi without Xtream add-on), or you want a single shareable URL.
Can you use both?
Yes. PrimeVision sends you both in the welcome email — the same account works on every device whether you use M3U or Xtream Codes. Use Xtream where supported, M3U everywhere else.
Start a free 24-hour PrimeVision IPTV trial and you will receive both M3U and Xtream credentials by email — pick whichever works best for your device. For app recommendations, check our best IPTV apps in 2026 guide.
