Yammer Files API limitation.

Hi ,

We are using https://www.yammer.com/api/v1/files.json?page= api url to fetch Files data. Increment page numbers to get data for subsequent pages.

Our Yammer Network has more than 40,000 files. We get data till page 30 (i.e for 750 files).
https://www.yammer.com/api/v1/files.json?page=31 returns no data.

Also the meta property for page 30 is_last_page has the value false. How can we get data for all the files on the network.

Any other approaches to follow or modification to api url.

Kindly guide/help in above matter.

Regards,
Rivin Jose
