Can't figure out how to get last page of data

API and Webhooks

Hi all,

Apologies in advance if this question has already been asked.

I’m using Python to paginate through all recordings for a user (/users/{userId}/recordings). I’ve looped through all the pages using the next_page_token value. So far it works, but I encounter a problem with grabbing records from the last page of results.

For example, we have a user with 64 recordings. That’s 3 pages of JSON data (30, 30, 4), since each page returns a maximum of 30 records. The first two pages of records are gathered, but not the last one with 4 records. I suspect this is because on the last page of data, the value of next_page_token is empty (e.g. "next_page_token": ""), and this causes my while loop to stop before it can grab the last page of records.

Here’s my code:

while recordings_data['next_page_token']:
    payload = { 
          'userId': 'user@site.com', 
          'from': '2020-01-01', 
          'next_page_token': recordings_data['next_page_token'] 
          }
    response = requests.get(url="https://api.zoom.us/v2/users/user@site.com/recordings", headers=AUTHORIZATION_HEADER, params=payload)
    recordings_data = response.json()
    recordings.extend(recordings_data['meetings'])
    return recordings

Many thanks for the help!

Hi rrodrigues,

I have similar code in PHP and solved it by using the array count on recordings_data for the while condition instead of the next_page_token existence. Here’s the php version which should translate pretty easily:

// initial request
$request = new ListAccountRecordingsRequest();
$request->setPageSize(300)
    ->setFrom('2020-02-02');
    
$response = $zoom->execute($request);
$recordings = $response->getRecordings();
$token = $response->getNextPageToken();

while ( count($recordings) > 0 ) {

    [ some processing ]]]

    if ( $token ) {
        // we have another page
        $request->setNextPageToken($token);
        $response = $zoom->execute($request);
        $recordings = $response->getRecordings();
        $token = $response->getNextPageToken();
    } else {
        // nothing left to grab
        $recordings = array();
    }
}

Hope this helps!

Thanks for this. I’ll try to port your code over and see if it works.

Ok, I eventually figured it out after debugging my code.

The problem wasn’t because the next_page_token key was empty on the last page of results like I had originally assumed. It was because I wasn’t updating the next_page_token variable with the new key. Foolish mistake!

Working code below:

for i in range(1, page_count):  # start at page index 1 since we already have the first page
    payload = { 'userId': email, 'from': RECORDING_START_DATE, 'next_page_token': next_page }
    response = requests.get(url=API_ENDPOINT_RECORDING_LIST(email), headers=AUTHORIZATION_HEADER, params=payload)
    recordings_data = response.json()
    next_page = recordings_data['next_page_token'] # update with new token
    recordings.extend(recordings_data['meetings'])

return recordings
