Hi all, I am currently checking out on Plex API and trying to maximize gains from using the API. This time: Adding an extra (trailer) to a movie that already has a trailer (chosen by Plex). According to documentation at [https://developer.plex.tv/pms/](https://developer.plex.tv/pms/) there’s a POST call to https://{IP-description}.{identifier}.plex.direct:{port}/library/metadata/{ids}/extras …. to add extras to a a Plex item (movie, for example). I set up a library containing a single movie that gets a movie trailer automatically. The GET call to the movie id/extras is working. Next, I want to add an new extra of subtype trailer to that movie. But the POST call always gets a 404 error. I know that there’s a 404 response if something’s not right, but no further info on why is shared. Tried a couple of ways to do it, but it always responds with 404. I construct the POST call using node.js script which I am happy to supply. Then I checked the [PMS logs](https://support.plex.tv/articles/200250417-plex-media-server-log-files/) what happens and I see the following: > Nov 30, 2025 18:43:12.419 [140677436054328] Debug — Request: [192.168.94.150:53998 (Subnet)] POST /library/metadata/224322/extras?url=http%3A%2F%[2Fcommondatastorage.googleapis.com](http://2Fcommondatastorage.googleapis.com)%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4&title=Injection+%28Local%29&extraType=1 (10 live) #ac7f69 GZIP Signed-in Token (rossinior) > Nov 30, 2025 18:43:12.422 [140677436054328] Debug — [Req#ac7f69/HCl#263b3] HTTP requesting GET [https://node.plexapp.com:32443/system/services/url/lookup?url=http%3A%2F%2Fcommondatastorage.googleapis.com%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4](https://node.plexapp.com:32443/system/services/url/lookup?url=http%3A%2F%2Fcommondatastorage.googleapis.com%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4) > Nov 30, 2025 18:43:12.422 [140678249032504] Warnung — [HttpClient/HCl#263b3] HTTP error requesting GET [https://node.plexapp.com:32443/system/services/url/lookup?url=http%3A%2F%2Fcommondatastorage.googleapis.com%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4](https://node.plexapp.com:32443/system/services/url/lookup?url=http%3A%2F%2Fcommondatastorage.googleapis.com%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4) (6, Couldn’t resolve host name) (Could not resolve host: [node.plexapp.com](http://node.plexapp.com)) > Nov 30, 2025 18:43:12.422 [140677529656120] Fehler — [Req#ac7f69] HTTP -6 downloading url [https://node.plexapp.com:32443/system/services/url/lookup?url=http%3A%2F%2Fcommondatastorage.googleapis.com%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4](https://node.plexapp.com:32443/system/services/url/lookup?url=http%3A%2F%2Fcommondatastorage.googleapis.com%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4) > Nov 30, 2025 18:43:12.422 [140678289795896] Debug — Completed: [192.168.94.150:53998] 404 POST /library/metadata/224322/extras?url=http%3A%2F%[2Fcommondatastorage.googleapis.com](http://2Fcommondatastorage.googleapis.com)%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4&title=Injection+%28Local%29&extraType=1 (10 live) #ac7f69 GZIP 2ms 379 bytes (pipelined: 1) > Nov 30, 2025 18:43:12.435 [140677436054328] Debug — Request: [88.134.29.122:53999 (WAN)] POST /library/metadata/224322/extras?url=http%3A%2F%[2Fcommondatastorage.googleapis.com](http://2Fcommondatastorage.googleapis.com)%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4&title=Injection+%28Public%29&extraType=1 (11 live) #ac7ffc GZIP Signed-in Token (rossinior) > Nov 30, 2025 18:43:12.437 [140677436054328] Debug — [Req#ac7ffc/HCl#263b4] HTTP requesting GET [https://node.plexapp.com:32443/system/services/url/lookup?url=http%3A%2F%2Fcommondatastorage.googleapis.com%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4](https://node.plexapp.com:32443/system/services/url/lookup?url=http%3A%2F%2Fcommondatastorage.googleapis.com%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4) > Nov 30, 2025 18:43:12.437 [140678249032504] Warnung — [HttpClient/HCl#263b4] HTTP error requesting GET [https://node.plexapp.com:32443/system/services/url/lookup?url=http%3A%2F%2Fcommondatastorage.googleapis.com%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4](https://node.plexapp.com:32443/system/services/url/lookup?url=http%3A%2F%2Fcommondatastorage.googleapis.com%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4) (6, Couldn’t resolve host name) (Could not resolve host: [node.plexapp.com](http://node.plexapp.com)) > Nov 30, 2025 18:43:12.437 [140677529656120] Fehler — [Req#ac7ffc] HTTP -6 downloading url [https://node.plexapp.com:32443/system/services/url/lookup?url=http%3A%2F%2Fcommondatastorage.googleapis.com%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4](https://node.plexapp.com:32443/system/services/url/lookup?url=http%3A%2F%2Fcommondatastorage.googleapis.com%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4) > Nov 30, 2025 18:43:12.437 [140678287686456] Debug — Completed: [88.134.29.122:53999] 404 POST /library/metadata/224322/extras?url=http%3A%2F%[2Fcommondatastorage.googleapis.com](http://2Fcommondatastorage.googleapis.com)%2Fgtv-videos-bucket%2Fsample%2FBigBuckBunny.mp4&title=Injection+%28Public%29&extraType=1 (11 live) #ac7ffc GZIP 2ms 379 bytes (pipelined: 1) Of course, I tried checking DNS for [node.plexapp.com](http://node.plexapp.com) and no DNS server knows this domain: [https://dnschecker.org/ns-lookup.php?query=node.plexapp.com&dns=dnsauth](https://dnschecker.org/ns-lookup.php?query=node.plexapp.com&dns=dnsauth) Therefore, what are the limits of using this POST call? Is there another way of adding a new trailer via API? I cannot find any “rules” for this API call. Is there any help that I can get on this? The URL in this example is just a dummy… some MP4 to test it.

Are no real URLs allowed? Is the presence of [node.plexapp.com](http://node.plexapp.com) a bug? I would love to see such a successful POST call from somebody, please. @drzoidberg33 ? Anybody?
