How to filter api responses based on date or status or any other fields? We need filter response from below endpoints.

/users/{userId}/webinars  
/webinars/{webinarId}/registrants  
/past\_webinars/{webinarId}/participants

I’m going to assume you’re using a JavaScript back end here for hitting these three endpoints. For all three, you can make use of simple [array filtering](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter).

For filtering the webinars, get the array object returned from `response.data.webinars` and filter it; you can use a library called `date-fns` to do some complex date-time tasks:

`import { parseISO, isAfter, isBefore, startOfDay, endOfDay } from 'date-fns';`  
`const items = response.data.webinars;`  
`const date1 = startOfDay(new Date('2025-04-15'));`  
`const date2 = endOfDay(new Date('2025-04-16'));`  
`const filtered = items.filter(item => {`  
` const time = parseISO(item.start_time);`  
` return isAfter(time, date1) && isBefore(time, date2);`  
`});`

Note that you’ll want to make sure that your start/end dates and the webinar `start_time` are in the same time zone, for accuracy, which is a simple ask for `date-fns`. Your best bet is to make sure everything’s cast to UTC.

For filtering the participants, do some similar filtering to `response.data.registrants`:

`const items = response.data.registrants`  
`const desiredStatus = "approved"; // or "pending" or "denied"`  
`const filtered = items.filter(item => item.status === desiredStatus);`

Hope this helps.

EDIT: Made my example code a little bit more perfomant haha

Hi Alex,

Thanks a lot for your reply. But is there a way to get a filtered response from the api itself, particularly the webinar one. Like get only webinars where registration is till open and start time greater than today for example.

Hi @Ramprabhu  
The List webinar registrant endpoint, offers a query param for status. But the List webinar participants does not have a query param for filtering. So I’d agree with @alexm and you would have to manage the filtering yourself

I do not believe you can make a request for webinars for a specific date or date range; as for the registration status, I don’t believe even the more granular webinar GET request returns that level of detail, either.

Have to love the concise code, adding this to my library.
