Hey @yaronhe,

Happy to help look into this for you. Can you please share the request URL and body you’re passing to this endpoint so that I can take a closer look? This will help me to debug.

Hi Will,
Here are the steps for reproducing the problem:

  1. I tried to retrieve the registrants list with the following API call:
    GET https://api.zoom.us/v2/meetings/94062863390/registrants
    and I received the following answer:
{

    "registrants": [

            "join_url": "https://openudev.zoom.us/w/94062863390?tk=........"

        }

    ]

}
  1. I created the following API call body by the registrant list from step 1:

{

"action": "cancel",

"registrants": [

    {

        "id": "SpjiucgMRb2nmknJgOPmSQ",

        "email": "20T7Ma1yoEnKL4hAM1StghmZApKMtY8U09yX-AnhQXE0@openudev.ac.il"

    },

    {

        "id": "HRlpzC-FT9y4JcrQqg8P8g",

        "email": "ggJMlReYlZPkO0fSFemGXI9f9San_WwWbG4gXe2rxpg0@openudev.ac.il"

    },

    {

        "id": "0RBQfipiQmyQeJr3d1muZQ",

        "email": "o5snIgRqc3T6A3kCi7ziA-q1tQxQqsojgaxhMUoH6SE0@openudev.ac.il"

    }

]

}

  1. I sent the following API call with the body from step 2:
    PUT https://api.zoom.us/v2/meetings/99727601374/registrants/status
    and i recieved the following answer: HTTP 204: No Content (positive answer)

  2. I tried to validate the positive answer in step 3 by re-sending the API call from step 1 and I received the same amount of registrants, all of them are approved, none of them canceled.

Hey @yaronhe,

Thank you for providing additional information. I’ve since reached out to an internal team in regard to this issue and will get back to you with more information as soon as I have it. (ZOOM-230264)

Thanks,
Max

Hey @yaronhe,

Thank you for your patience. Our internal team got back to me and indicated that the parameters used when cancelling a meeting registrant were added as parameters to the request when they should instead be added as a request body. Please make sure that you are using a request body instead of parameters to make the request and that the client you are using to make the request is operating as expected.

I hope that helps! Let me know if you have any questions.

Thanks,
Max
