Products have varying delivery frequency needs. For instance, a daily cleanser should be delivered more frequently than a weekly hair mask. Similarly, a larger product size should be delivered less often compared to a smaller one.

Now, you have the option to specify a different delivery frequency when making product swap recommendations through Quick Action URLs. If you don't specify a new frequency in the URL, it will automatically default to the frequency of the product in the current subscription.

How does it work? See the documentation here.
