I am trying to retrieve a complete list of the channels subscribed to the authorized user.
According to Subscriptions: list:
To retrieve a complete list of subscribers, use the mySubscribers parameter. That parameter, which does not return subscribers in a particular order, does not limit the number of subscribers that can be retrieved.
However, even with this parameter, I am limited to retrieving 1000 results.
I am using Node.js. My parameters are the following:
{'params': {
'part': 'snippet,contentDetails,subscriberSnippet',
'mySubscribers': true,
'maxResults': 50
}};
The request goes to this URL:
https://www.googleapis.com/youtube/v3/subscriptions?part=snippet%2CcontentDetails%2CsubscriberSnippet&mySubscribers=true&maxResults=50
According to the pageInfo:
"pageInfo": {
"totalResults": 12954,
"resultsPerPage": 50
},
I continue to request using nextPageToken:
function subscriptionsListByChannelId(auth, requestData) {
var service = google.youtube('v3');
var parameters = removeEmptyParameters(requestData['params']);
parameters['auth'] = auth;
service.subscriptions.list(parameters, function(err, response) {
if (err) {
console.log('The API returned an error: ' + err);
return;
}
console.log(response);
if (response.data.nextPageToken) {
var newParams = {'params': {
'part': 'snippet,contentDetails,subscriberSnippet',
'mySubscribers': true,
'maxResults': 50,
'pageToken': response.data.nextPageToken
}};
authorize(content, newParams, subscriptionsListByChannelId);
}
});
}
response.data.nextPageToken becomes undefined after exactly 1000 subscribers, meaning it has reached the last page.
I cannot figure out why it stops at this point. According to the documentation, I should be able to retrieve all subscribers, not just 1000. I have tried every combination of parameters I can think of, but nothing changes.
EDIT: For anyone stumbling across this question in the future, I noticed Channels: list gets more than 1000 subscribers, despite the mySubscribers parameter being deprecated. By switching the API, you can retrieve more subscribers, although they are about 72% duplicates. Because of the issues of both APIs, I don't see this as the solution.
