ZoomMarket place, oAuth not returning Tokens

Hi,

We released our app at Zoom in 2020 and since then its been working fine. Recently rebranding happened for our company and we had to update the app hosted at zoom market place as well to update the app.

Unfortunately, after updating the branding at Zoom, our app has stopped working and since then we are struggling to get the customers happy with the zoom integration.

We are able to get the auth code, but while trying to generate the tokens its returning error. Please find the request below and let us know if we are missing something?

URL: https://zoom.us/oauth/token
AccessTokenPayload: grant_type=authorization_code&code=XXXXXXXXXXXX&redirect_uri=https://core.abc.com/?route=d/a/zoom
Response: {“reason”:“Invalid request : Redirect URI mismatch.”,“error”:“invalid_grant”}

We have already cross checked multiple times and all details are correct.
Please suggest.

@manish.agarwal as a first step, can you make sure that the Redirect_url in your app is the same one that you are using to make the OAuth token request?
