Get latest uploads using the v3 version of YouTube gData - youtube-api

Question

Does anyone know how to get the latest uploads for a specific channel (or user will do too)?
In v2 of the gdata api you had the 'http://gdata.youtube.com/feeds/users/[username]/uploads?alt=json' call. But that's deprecated. In v3 there's the youtube.activities.list function, but that doesn't give the same results.
I thought I could get the playlists first, but than I seem to be missing some uploads that are not in a playlist.
Any suggestions?

Answer 1

To get the lastest uploads of a specific channel, don't pass by : youtube.activities.list.
The YouTube API V3 provide a special playlist of the uploads.
To get the id of the playlist two important link :
https://developers.google.com/youtube/v3/docs/channels/list?hl=fr
https://developers.google.com/youtube/v3/docs/playlistItems/list?hl=fr
And the two steps to get the uploads :
You need to use youtube.channel.list with the parameters :
part=contentDetails
id=ID_OF_THE_CHANNEL
The result is like this :
{
"kind": "youtube#channelListResponse",
"etag": "\"kjEFmP90GvrCl8BObMQtGoRfgaQ/CMNDR4CfkeuPx4qnAlqzH11BB5A\"",
"pageInfo": {
"totalResults": 1,
"resultsPerPage": 1
},
"items": [
{
"kind": "youtube#channel",
"etag": "\"kjEFmP90GvrCl8BObMQtGoRfgaQ/MeyW1Z8CbXCFwqPMlOLEwNZyMc0\"",
"id": "UCzOpxz1sdfp_0eRYqXkoSNA",
"contentDetails": {
"relatedPlaylists": {
"likes": "qsdqsxz1y8np_0eRYqXkoSNA",
"uploads": "qsdqsd1y8np_0eRYqXkoSNA"
},
"googlePlusUserId": "151...45515"
}
}
]
}
The playlist id of the uploads : items -> contentDetails -> uploads
Now you need to call the API a second time with youtube.playlistItems.list with the parameters :
part=snippet
playlistId=ID_OF_THE_PLAYLIST_UPLOADS
The result is like this :
{
"kind": "youtube#playlistItemListResponse",
"etag": "\"kjEFmP90GvrCl8BObMQtGoRfgaQ/bS4qNeqE0hEI-qb_r8hcbN9G1sE\"",
"nextPageToken": "CAUQAA",
"pageInfo": {
"totalResults": 38,
"resultsPerPage": 5
},
"items": [
{
"kind": "youtube#playlistItem",
"etag": "\"kjEFmP90GvrCl8BObMQtGoRfgaQ/ItttPAEwALDI0QdLoylbdN6oHcY\"",
"id": "UUT2INYKRKg8bTaC4Z8-faCKSOt7nfZDHN",
"snippet": {
"publishedAt": "2014-08-12T09:45:41.000Z",
"channelId": "UCM1Bnpxipb8H4GJoITnJ0XQ",

"resourceId": {

}
}
},
...
The uploads are sort by date. Lastest upload is the top of the list.
Hope it's help !
