I am having the following problem

When I want to add a record to a webinar, it records it BUT NOT ON THE WEBINAR I CHOOSE

I register for the webinar occurrence\_id 4836817008000, but the API response is that it registers me for the webinar occurrence\_id 1686855600000, which is another date

I send you the JSON that I send to the API

{\n “email”: “[braulio000@gmail.com](mailto:braulio000@gmail.com)”,\n “first\_name”: “braulio”,\n “last\_name”: “braulio”,\n “address”: “”,\n “city”: “”,\n “country”: “”,\n “zip”: “”,\n “state”: “”,\n “phone”: “0303456”,\n “industry”: “”,\ n “org”: “”,\n “job\_title”: “”,\n “purchasing\_time\_frame”: “”,\n “role\_in\_purchase\_process”: “”,\n “no\_of\_employees”: “”,\n “comments”: “”,\n “custom\_questions”: [\n {\n “title”: “Company Name”,\n “value”: “test”\n }\n],\n “source\_id”: " 3516709478244",\n “uuid”: “83085171987”,\n “occurrence\_id”: “4836817008000”,\n “token”: “MY\_TOKEN\_HIDDEN”\n}

I send you the response that the API returns

{‘registrant\_id’: ‘weE31zbFQ8O7b8SM0ZGMEQ’, ‘id’: 83085171987, ‘topic’: ‘PEPs’, ‘start\_time’: ‘2023-07-20T14:00:00Z’, ‘join\_url’: ‘[https://nosis](https://nosis).

I send you the URL that I consult

[https://api.zoom.us/v2/webinars/83085171987/registrants?occurrence\_id=483681700800](https://api.zoom.us/v2/webinars/83085171987/registrants?occurrence_id=483681700800)

EXPECTED RESPONSE

{‘registrant\_id’: ‘weE31zbFQ8O7b8SM0ZGMEQ’, ‘id’: 83085171987, ‘topic’: ‘PEPs’, ‘start\_time’: ‘2023-07-20T14:00:00Z’, ‘join\_url’: ‘[https://nosis](https://nosis).

The [Add a webinar registrant documentation](https://developers.zoom.us/docs/api/rest/reference/zoom-api/methods/#operation/webinarRegistrantCreate) states that the URL query string parameter should be `occurrence_ids` (plural), not `occurrence_id` (singular) as used in your example URL.
