Hello good day,
I would like to know how to do the following:
I want to send an email to a certain group of users.
The mail will have a link that points to the purchase button of a certain product, so that you can reliate the payment. I just wish that product was available for that group of users and did not appear on the web as a public:
1) What is the specific link that I have to insert in the email?
2) That this link is only usable by people belonging to that group of users.
Thank you

Hello good morning,
that option is already using it and it works correctly.
But in this case I would like it to look like a payment reminder with the payment link. Same as when you get the email with the status of a product, but with a link type pay now.
Thanks!

Hi Nicolas,
If that's exactly what I mean. We are a university We give the option to buy in advance the courses to the students that pass of level.

Then we put on sale the rest of the remaining products.

Therefore, it is impossible to do. Or is there any way to massively generate orders for a given number of students in certain products?

Thanks

Thanks NIcolas,


Is it possible to change the access level (ACL) by means of mass actions filtering by course in the existing orders?
