Google Photos API, pageSize Parameter not returning expected results

Question

Using the Google Photos API Explorer I am trying to limit the number of albums returned using the albums.list method.

If I set pageSize = 10, the api explorer returns 5 albums, if I set it to 3 in returns 1 album.

Any suggestions as to why I am not seeing the same number of albums in the response as is set via the pageSize parameter?

Thanks

The page size describes the desired maximum number of results, but it is no guarantee.

If you need at least 10 results from a single request, your best option would be to request a higher page size as you have found. Alternatively, you can always make additional requests using the nextPageToken.

(We have some plans to improve this in the future and return a number of results that's equal, or even closer, to the page size. Unfortunately, at the moment we can't guarantee the number of results in a request, but we always try to fill a page size if possible.)
