We have a web app. We use the zoom REST api v1 to create meetings. We use JSON as the data format. For the last year we have been able to pass in “” for the topic and it worked fine. Now all of a sudden if we pass “” for topic we get an error: Invalid input parameter: topic Did something change? ---

Hi andrew Zoom api v1 has made some chages,so the “topic” should be not empty see as [https://zoom.github.io/api-v1/#create-a-meeting](https://zoom.github.io/api-v1/#create-a-meeting) . But version 1 of the Zoom API is being sunset and will no longer be supported after November 1st, 2018.It is recommended that you start developing with [Version 2](https://zoom.github.io/api/) of the Zoom API.And in version 2 you can pass “” for topic ---
