When do I verify the email before creating a subscription with stripe?

Question

1. I know stripe doesn't have anything to do with verifying emails.
2. I have a form on my website where I collect a new user's email, password and cc info.
3. As of now I do not verfiy the user's email. I simply create the user in my system and create the strip user and subscription after I get the card token with stripe.js.
4. I want to verify the email address, but I am not sure at what point in the process to do it. I don't think it makes sense to charge the customer and start the subscription and then verify the email address.

Should I wait and start the stripe subscription when the customer verifies the email address? It seems like this is one of the most common scenario's online. Is their a best practice for this scenario?

Again, I am not asking technically how to verify the email address (I use firebase auth), I just want to know when I should and how it should fit into my onboarding flow.

You can after Firebase Auth account creation, check if the emailVerified is true. If not, send an email verification and pass a continueUrl to continue the subscription process, instructing the user to check their email to continue the subscription process. This is a common process for many subscriptions that require email verification.

You can learn more about passing continueUrl via email verifications: https://firebase.google.com/docs/auth/web/passing-state-in-email-actions

You can build your own custom landing page where you continue the subscription using the following instructions: https://firebase.google.com/docs/auth/custom-email-handler

Make sure you check email_verified in the idToken after ID token verification to confirm verification, server side.
