Hi Zoom Team; We want to use APIs to process user add-on like webinar; large meeting. But we cannot find APIs to process these add-on for user. Do you have any recommend about this case ? Thanks and Best Regards. ---

Hi @anhnt, The API methods you’re looking for can be found [here](https://marketplace.zoom.us/docs/api-reference/zoom-api/billing/accountplanaddoncreate). However, this API can only be used by master accounts that pay all billiing charges of their associated Pro or higher sub accounts. Zoom allows only to use master APIs and manage sub accounts’ subscriptions. You’ll need to email the partner programs team at **[partner-success@zoom.us](mailto:partner-success@zoom.us)** for more information, and to gain access to these APIs. Thanks, Alex ---

Hi @alexmayo ; I understand that APIs “[https://api.zoom.us/v2/users/{userId}/webinars](https://api.zoom.us/v2/users/%7BuserId%7D/webinars)” is for the task that Subscribe a sub account to a Zoom addon plan. The situation is: We are master account and we have sub-account with add-on webinar subscribed already. instead of we must assign manually on web manager, we want to **use APIs to assign webinar add-on to specified users** on sub-account. Thanks ---

Hey @anhnt, Thank you for reaching out to the Zoom Developer Forum. If you are looking to change the settings of a user on a sub account, you can try using our [Master Account Update User Settings API](https://marketplace.zoom.us/docs/api-reference/master-account-apis/user-apis#user-apis:~:text=%2Fv2%2Faccounts%2F%7BaccountId%7D%2Fusers%2F%7BuserId%7D%2Fsettings%20Update%20user%E2%80%99s%20settings%20on%20Zoom%20via%20user%20ID.). The request body for that API should be the same as the account level [Update User Settings API](https://marketplace.zoom.us/docs/api-reference/zoom-api/users/usersettingsupdate) which means that you can set `feature.webinar` to `true` in order to apply a webinar license to a user on a sub account: ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/e/9/e9df5aa27adeced71277ec63eace9e0f540b5cab.png) Let me know if that helps. Thanks, Max ---
