Woocommerce integration questions

Hi, we cannot use your payment system unfortunately, we are obliged to go through WooCommerce. However, it is not clear how does the woocommerce payment process links with the user registration forms.

We are considering buying the premium version, but can you please confirm if this is possible with your plug in and with the woocommerce integration payments.

The use case, we want to create a registration system for a marathon race, which will have three races option => one WOOcommerce product with three variations, therefore three different prices.

1. Can one account register multiple users in one subscription form and pay for each subscription in bulk? something like this: https://gravitywiz.com/register-multiple-users-from-a-single-form/
2. Display the list of registered users in a form of a list in the front end. Ideally, different tables need to be displayed for each of the product variations.
3. We need to find a way to assign a different number string to each of the product variations, e.g. 5K race assign number from 1000 to 1999 10K race assign number from 2000 to 2999, 21K race assign number from 3000 to 3999

Is this possible?

Also, I watched the available videos and I only understood how does woocommerce integrate, but i couldn’t see how does the registration process go when we have a woocommerce integration. Is there a video about that?
