Could you please clarify how zoom oauth2 app approval will use the “Development” app credentials? To install our app, users are required to sign in to our website first and then initiate the zoom oauth2 process from there. We will provide a special username and password for signing into our website when we submit the app for approval. When the oauth2 process starts, we will choose the “Development” credentials if the signing user is the special user we provide in app submission and choose the “Production” credentials for all other users. Will this work? ---

Hey @rjd, Yes that will work. This can be communicated further once you have submitted your app and in the testing phase. Thanks, Tommy ---
