Glad it works @chenrui, this is correct - you will need to add a Redirect URL to your whitelist. Let us know if we can help! ---

Hi Michael Thanks for your response. This is first time I’m working on ZOOM API. Appreciate all your helps. I’m working on a web application witch allow SUSS staff to search ZOOM recordings by Keywords within SUSS account. 1. to do this searching, what the scope needed for my client settings? 2. what are the API should I use, I cannot find a “searching” API in the document. Thanks in advance for your help. Looking for your response. Best Regards, Chen Rui ---

Hey @chenrui, You will need to use the [List Users API](https://marketplace.zoom.us/docs/api-reference/zoom-api/users/users), but it does not support searching, so you will have to implement the search logic on your end. Thanks, Tommy ---

Hey @chenrui, See my post here: > [@Defining from with requests to API using JWT not behaving as expected](https://devforum.zoom.us/t/defining-from-with-requests-to-api-using-jwt-not-behaving-as-expected/8770/9): > > Hey @lane, It appears that endpoint only returns data in one month increments. In order to return all the data from the past 6 months you will need to make the requests in the following ways: [https://api.zoom.us/v2/users/{userId}/recordings?to=2020-03-19&from=2020-02-19](https://api.zoom.us/v2/users/%7BuserId%7D/recordings?to=2020-03-19&from=2020-02-19)[https://api.zoom.us/v2/users/{userId}/recordings?to=2020-02-19&from=2020-01-19](https://api.zoom.us/v2/users/%7BuserId%7D/recordings?to=2020-02-19&from=2020-01-19)[https://api.zoom.us/v2/users/{userId}/recordings?to=2020-01-19&from=2019-12-19](https://api.zoom.us/v2/users/%7BuserId%7D/recordings?to=2020-01-19&from=2019-12-19) And so on… Let me know if that works! Thanks, Tommy Thanks, Tommy ---
