Selling online subscriptions product with customer login

Hi,
I have a question about selling online subscriptions with Zoho Subscriptions. Let's say I'd like to sell Matomo analytics with a monthly rate. I can set up a Zoho Subscription plan and host the payment page on my website. But how can I connect the subscription plan to the third party service to manage access. For instance, if the customer cancel his plan, I need to prevent him from accessing Matomo account. For now, there is no link between these two apps.
Do you have any ideas, documentations or something else that could lead me in the right direction?
Thanks!
