Invalid redirect: https://xxxx-xx-xxx-x-xxx.ngrok-free.app/auth (4,700)

[attentiontag (Arvind)]

Description

I have a new App Attention Tag Test (App Marketplace) that I have configured copying from GitHub - zoom/zoomapps-sample-js: A Hello World Zoom App built with Vanilla JS

The ngrok site / server is on https://2937-42-106-9-255.ngrok-free.app/ - which opens locally, when but when attempting to install - zoom gives the errors.

The URLs in Zoom & App seem ok. Is it possible to check what maybe wrong? I see some earlier threads with the same 4700 error, but haven’t been able to find the solution from them.

Hope you will be fine.

Please make sure that you have added redirect url to allowed list.

[attentiontag (Arvind)]

Have them already added - screenshots attached.

Please add base url without /auth. And also verify that from app you have same redirect uri with /auth.

The /auth URL works independently. Where do you suggest adding the base url (without ‘auth’) - in the Home page URL or somewhere else? I have that added to Homepage URL. Thanks

In allowed list you need to set base url https://example.ngrok-free.app, also baseUrl/auth one.

Then please verify that you have also added that redirect uri to your app source code.

Thanks
