Version of the custom_component

[v0.8.4]

Describe the bug

Sets up in HA correctly, seems to connect to Zoom ok. However, Zoom says I cannot activate the app without Event Notification Endpoint Validation, and I cannot get it to validate. I am using the Nabu Casa URL, it ends in ui.nabu.casa/api/zoom. I believe I am not getting any notifications because the app is not 'active'.

For more context, I checked logs and I'm also getting an error from within HA.

I switched companies and no longer use Zoom. As such I have limited capacity to fix bugs. I will add a note to the README but would welcome contributions to keep this integration working.

It seems the issue stems from Zoom requiring webhook events to be verified now. https://marketplace.zoom.us/docs/api-reference/webhook-reference/#verify-webhook-events They are removing the Verification token and using a Secret Token now. I was able to connect the integration by passing in the Secret Token instead but it seems the validation process wanted on the Features screen in the Zoom dev area needs what is talked about in that URL. My logs show this (line breaks added for readability):

Received unauthorized request: 
{"payload":{
  "plainToken":"<redacted manually>"},
  "event_ts":1670946927462,

For what it's worth @bfenty - I got the same error but was still able to complete the setup and have connected it to HA successfully.

Thanks for the reply. It actually did start working for a bit then it has quit again.

@bfenty Did you try validating the URL after the integration was setup and working in Home Assistant? That seemed to work for me, too.

I think this issue is related to the challenge-response checks from zoom. There is an initial validation and then revalidation.

https://developers.zoom.us/docs/api/rest/webhook-reference/#validate-your-webhook-endpoint

Having the same issues as described above. It works for a bit, when the revalidation happens, there is nothing to handle it so zoom just stops sending updates.
