Whay are these same Youtube API REST urls returning different results? - youtube-api

Question

My code uses this URL https://www.googleapis.com/youtube/v3/channels?part=id&snippet&id=UC9ctsJZ2aD1nCexfqj342NQ&key=[API_KEY]
which returns
{
"kind": "youtube#channelListResponse",
"etag": "69nKH4yrkGqjpjRH2T_M86dyIUI",
"pageInfo": {
"totalResults": 1,
"resultsPerPage": 5
},
"items": [
{
"kind": "youtube#channel",
"etag": "A0IqlEsff608TjGHRdSAoqyeaiw",
"id": "UC9ctsJZ2aD1nCexfqj342NQ"
}
]
}
The sample code at https://developers.google.com/youtube/v3/docs/channels/list
has this call
curl \
'https://youtube.googleapis.com/youtube/v3/channels?part=id%2C%20snippet&id=UC9ctsJZ2aD1nCexfqj342NQ&key=[YOUR_API_KEY]' \
--header 'Authorization: Bearer [YOUR_ACCESS_TOKEN]' \
--header 'Accept: application/json' \
--compressed
And it returns the data I'm expecting:
{
"kind": "youtube#channelListResponse",
"etag": "oMV3kRZIiTu9TJSfDOaPpFGwsV0",
"pageInfo": {
"totalResults": 1,

I can't see why snippet is being left out of the response for my API call.

Answer 1

Your URL is slightly incorrect.
Your code says &part=id&snippet& but the YouTube example says &part=id, snippet& (with ", " escaped to %2C%20).
