'Microsoft Teams channel webhook URL format validation - any consistent pattern/documentation?

I'm building an app that allows the user to input a Teams channel webhook connector URL for notifications.

I want to be able to do some basic validation on the URL to maximize the chance that the user's input is valid.

From what I can see on the few M365 tenants I have access to, the webhook appears to be in the format of:

https://tenant-name.webhook.office.com/webhookb2/some-guid/IncomingWebhook/some-guid/some-guid

But I'm not sure if that'd be the case for all tenants, and I believe at some point Microsoft changed this format too, as I have seen this one before:

https://outlook.office.com/webhook/some-guid/IncomingWebhook/some-guid/some-guid

So I'd need to have all versions accounted for.

I can't seem to find any documentation on this. If by any chance someone has worked on this and can provide some info, it'd be greatly appreciated.

We have verified it now in our tenant and the Webhook URL is similar to the one which you have shared first:

https://tenant-name.webhook.office.com/webhookb2/some-guid/IncomingWebhook/some-guid/some-guid

So you can use this format.
