Customer import via csv and Cron Job (url)

[gosrl]

Hello,

I'm looking for a module to import customers from a remote csv into Prestashop (1.7.x), using a cron job.

The module should be able to:

• import a csv (containing all customers information) via URL. This operation should be done every 3 hours (it's not needed for the module to have a cron function, I just need the cron URL and I'll create the cron job myself)
• create/update customers inside Prestashop

I searched a solution for this on Prestashop Module, but I didn't find anything suitable.

I've also found a guide to import customers manually (https://www.hiddentechies.com/blog/prestashop/import-customers-prestashop/), and I can see there's an option to import files using FTP, but the option is greyed out (see screenshot attached) and I'm not really sure I'll be able to do that using a Cronjob.

What solution do you suggest?

Thank you
