Xtream Codes API vs M3U playlist: how IPTV logins work (UK setup guide)

Short answer: an IPTV login usually comes in one of two forms. An Xtream Codes API login is a server URL plus a username and password, and the player app fetches channels, films, series and the TV guide as separate JSON lists. An M3U playlist is one text file (or one URL) listing every stream, with the TV guide added separately as an XMLTV link. For most viewers in the UK, Xtream Codes is the easier choice because categories, catch-up and the guide load on their own.

This guide explains what each format contains, which UK devices and player apps accept which, and how to fix the usual setup problems. It is written by Televo IPTV, a UK IPTV provider, so the last section lists our plans; everything above it applies to any provider.

What is an M3U playlist?

M3U is a plain-text playlist format. Each channel takes two lines: an #EXTINF line with metadata, then the stream URL.

#EXTM3U
#EXTINF:-1 tvg-id="channel.uk" tvg-name="Example Channel" tvg-logo="https://example.com/logo.png" group-title="UK | Entertainment",Example Channel
http://provider.example:8080/live/USERNAME/PASSWORD/12345.ts

• tvg-id matches the channel to its entry in the TV guide (EPG).
• group-title is the category the player shows.
• The URL at the end is the stream itself.

Providers normally give you an M3U URL rather than a file, so the list updates when channels change. A typical URL looks like this:

http://provider.example:8080/get.php?username=USERNAME&password=PASSWORD&type=m3u_plus&output=ts

type=m3u_plus adds the tvg-* and group-title attributes. output=ts asks for MPEG-TS streams; some players work better with output=m3u8 (HLS).

What is the Xtream Codes API?

Xtream Codes API is a login style used by most IPTV panels. Instead of one big playlist, the player calls small endpoints and builds its menus from the answers:

http://provider.example:8080/player_api.php?username=USERNAME&password=PASSWORD
http://provider.example:8080/player_api.php?username=USERNAME&password=PASSWORD&action=get_live_categories
http://provider.example:8080/player_api.php?username=USERNAME&password=PASSWORD&action=get_live_streams
http://provider.example:8080/player_api.php?username=USERNAME&password=PASSWORD&action=get_vod_streams
http://provider.example:8080/player_api.php?username=USERNAME&password=PASSWORD&action=get_series
http://provider.example:8080/xmltv.php?username=USERNAME&password=PASSWORD

The first call returns account details as JSON: status, expiry date and how many connections are allowed. In the app you only type three things: the server URL (http://provider.example:8080), the username and the password.

Xtream Codes or M3U: which should I use?

	Xtream Codes API	M3U playlist URL
What you enter	Server URL, username, password	One long URL
Live TV, films and series	Separate menus, loaded on demand	All in one list (films and series often missing or flat)
TV guide (EPG)	Loaded automatically	Add the XMLTV URL yourself
Catch-up	Supported where the channel and app support it	Usually not
Load time on big lists	Fast, loads per category	Slower, whole file at once
Best for	TiviMate, IPTV Smarters Pro, XCIPTV, IBO Player Pro	Apps that only accept playlists, VLC, Kodi PVR IPTV Simple Client

If your app supports both, use Xtream Codes. Use M3U when the app only accepts a playlist, or for a quick test in VLC.

Which UK devices and player apps accept each format?

Device	Common apps	Xtream Codes	M3U
Amazon Fire TV Stick / Fire TV (Fire OS)	TiviMate, IPTV Smarters Pro, XCIPTV (sideloaded with Downloader)	Yes	Yes
Android TV / Google TV	TiviMate, OTT Navigator, IPTV Smarters Pro	Yes	Yes
Samsung (Tizen) and LG (webOS) TVs	IBO Player Pro, Smart IPTV	Depends on app	Yes
iPhone and iPad	GSE Smart IPTV	Yes	Yes
MAG boxes	Built-in portal	No, uses a portal URL tied to the MAC address	No
Windows / macOS / Linux	VLC, Kodi	Kodi add-ons only	Yes

Note: the Fire TV Stick 4K Select runs Vega OS, not Fire OS, so it cannot sideload these Android apps.

How do I fix common IPTV login errors?

• "Authorization failed" or 401: check the username and password for spaces, and that the server URL includes the port (:8080 or whatever your provider gave).
• Channels load but the TV guide is empty: for M3U, add the XMLTV URL; then make sure the tvg-id values match. In TiviMate, update the EPG manually once.
• "Max connections reached": another device is still streaming on the same login. Most plans allow one connection at a time; stop the other device or wait a minute.
• Buffering: test your broadband speed on the same device. Plan for about 15 Mbps for HD and 25 Mbps for 4K. Use Ethernet or 5 GHz Wi-Fi, and try switching output=ts to output=m3u8.
• Playlist too large to load on a Smart TV: use Xtream Codes, or ask your provider for a filtered list with fewer categories.
