Pull out random portfolio item from a category

Hi,

I would like to create a URL to pull out a random portfolio item from a particular portfolio category.

I tried to follow the advices of two similar topic (https://www.ads-software.com/support/topic/random-product-from-specific-product-category/ and https://www.ads-software.com/support/topic/url-to-random-posts-in-specific-category/) but it didn’t work for me.

I would like a URL that pull out a random item from “Recette” category (ID number 50).

I tried this:
https://www.example.com/?redirect_to=random&post_type=portfolio&cat=50
And also that:
https://www.example.com/?redirect_to=random&post_type=portfolio&custom_taxonomy_slug=portfolio_cat&custom_taxonomy_field=slug&custom_taxonomy_term=recette

But both didn’t work.

Could you please help me?

Thank you!!!

Manon
