Error code 2013 indicates that the SDK received invalid parameters for the join Session method. Check the parameters you passed to the join method.

I am also getting the 2013 error and not sure what am i doing wrong. The documentation says some backend db error without any further details here > **[Video SDK - Android - Integrate](https://developers.zoom.us/docs/video-sdk/android/integrate/#error-codes)** > > The Zoom Developer Platform is an open platform that allows third-party developers to build applications and integrations upon Zoom’s video-first unified communications platform. The sdk logs seems to be in encrypted format. Blocked here… Need some working example for Zoom sessions (Not zoom meetings) where there is no need to provide zak tokens for joining a session. ---

@balajisunku duplicate question answered here. > [@Getting error 2013 while creating a session from Android sdk](https://devforum.zoom.us/t/getting-error-2013-while-creating-a-session-from-android-sdk/97458/2): > > @balajisunku from what you are mentioning, it seems that you are using the Meeting SDK App Type instead of the Video SDK App Type. These are 2 different products If you are using a Video SDK, you will need to create a Video SDK App Type. You can sign up for a Video SDK account here [Buy it now - Zoom](https://zoom.us/buy/videosdk) The marketplace app should look something like this
