Zoom Oauth has started failing with 403

API and Webhooks
1

We have been using the following link successfully to all users to use our Zoom integration but it has started failing with a 403 in the console when clicking apply. It lets you sign in with Zoom credentials.

https://zoom.us/oauth/authorize?client_id=xxxxxxxxxxxx&response_type=code&redirect_uri=http%3A%2F%2Flocalhost%3A3001%2Fcallback&code_challenge=pBvokOmo_vU_rFF4MeFzkkUbVJOGVGPCH14UHuQAhM4&code_challenge_method=S256

The localhost server is running ok for the code.

Any ideas what is going wrong?

Also seeing this issue.

That’s because of “localhost” in redirect URI, see related topic:

https:// devforum.zoomus/t/403-error-in-oauth-redirect-url-occurs-in-development-environment-when-url-includes-localhost/137433

Unfortunately, haven’t found any fix for that yet, but it is clearly smth on Zoom’s side to fix. It worked before.

We have been using localhost successfully in both development and production for more than a year until it started failing this week.

I presume something has changed recently.
