How to change page results with YouTube Data API v

Question

I'm trying to get video data from the YouTube API (v3) using this example:

https://developers.google.com/apis-explorer/#p/youtube/v3/youtube.search.list?part=snippet&maxResults=25&order=relevance&q=site%253Ayoutube.com&topicId=%252Fm%252F02vx4&_h=1&

The problem is that I don't understand how to change the page results. For example this query gives me 25 items (maxResults=25) but total results are --> "totalResults": 548669. So the big question here is how to move on page 2 and receive the other 25 results?

Answer 1

If you look at the results, you will see a "nextPageToken" item right after "pageInfo". This needs to be passed as the pageToken on your next request.

So if you make a call to this api:

https://www.googleapis.com/youtube/v3/search?part=snippet&maxResults=25&order=relevance&q=site%3Ayoutube.com&topicId=%2Fm%2F02vx4&key={YOUR_API_KEY}

You would make a call to this one for the next page:

https://www.googleapis.com/youtube/v3/search?pageToken=CBkQAA&part=snippet&maxResults=25&order=relevance&q=site%3Ayoutube.com&topicId=%2Fm%2F02vx4&key={YOUR_API_KEY}
