I put a lot of thought into this one and finally managed to connect Stripe to Telegram, Google Drive and sending a custom confirmation email. I used Integromat.com for this and happy that it works.
When the client receives his welcome email he has an option to create a meeting with me via Calendly that automatically creates a Zoom.us meeting.
In the future I would like to create a custom Stripe payment page that has all of this included.
Let us hope all goes well when it goes live.
