Related Lists naming convention

Related Lists naming convention

Is there any naming convention on related lists?

I need to get all the products assigned to a potential, but I don't know what should be de URL for the getRelatedRecords api method, since I don't know how the related list is called.

I'm asking this, because the "Stage History" related list name is "potStageHistory"... So, what is the name of "Products" related list?

Thanks
