How to Delete a Contact <-> Product relationship?

How to Delete a Contact <-> Product relationship?

How can I, with the API, remove a relationship between a Contact and a Product?  This is needed for example, when a customer has returned a product and we want to update Zoho to reflect that.

Basically what I am looking for is the exact opposite of https://help.zoho.com/portal/en/community/topic/adding-a-product-to-a-contact-via-api

Thank you!

                                                                                                              Hello Zoho CRM, How do I update "Lead Status" to more than 100 records at once? To give you a background, these leads were uploaded or Imported at once but the lead status record was incorrectly chosen. So since there was a way to quickly add records in the system no matter how many they are, we are also wondering if there is a quicker way to update these records to the correct "Lead Status". I hope our concern makes sense and that there will be a fix for it. All the best, Jonathan
