Launch Https request to import data

[fifisave]

Hello, I would like to know the best way to run an HTTPS command like this one :

https://just-family.fr/wp-load.php?impor...processing

for importing around 2000 product records into a Wordpress database.

May I use the Open website task ? I try this, but it seems that there is a timeout and the task does finish correctly because it may take 15 to 20 minutes for 2000 products.
Or Run a program task ?
Or Run a Script task ? But in this case which one to choose please?
Regards
