Create a B2B solution for Wix / Velo

I have a WIX page and need a B2B solution. The Manager at the customer's company should be able to do the following: 1. Purchase multiple licenses for an online course. The purchasing process should be handled by WIX. The course itself is not hosted on WIX but on a separate learning management system (LMS). 2. After purchasing, the manager goes to a custom page (called Users) on their account on my WIX site where they can add and remove users to the course. The number of users he can add should be restricted to the number of licenses he has purchased. 3. After adding a user, the underlying code should send a webhook to the LMS and enroll the user. Only after getting a webhook confirmation back from the LMS, should the enrolled user be added to the WIX database, the list of users be updated and a confirmation message be shown to the Manager. 4. When the manager deletes a user, the user should also be un-enrolled from the course using webhooks. The same process here with confirmations. - If the subscription expires, the users should be un-enrolled from the course automatically after the Manager has received a payment reminder and still not paid. - The Manager should be able to purchase extra licenses to be able to add extra users. This should be done by adding a separate subscription. - The Users should be registered with Email, First name, Last name. - In order to know which users to delete in case of missing payment, the order number for the subscription should be stored to the user's database entry in WIX. - The add-users form should be extendable. That means that the first row of the form should contain Email, First name and Last name. After entering this data, the Manager should be asked if he wants to add more users. If yes, then a second row is added to the form and he continue to add all of the users to the form BEFORE he click on the Submit button. - To delete users, there should be checkboxes in front of each row plus one "select all" checkbox on the top, as well as a "Delete checked users"-button. After clicking this button there should be a confirmation (Are you sure?) popup. Documentation: LMS API doc: [login to view URL]
