SUB Operation

PUT https://{{base_url}}/v3/content_types/{{content_type_uid}}/entries/{{entry_uid}}

The SUB operation works the opposite of ADD. It reads the latest value of a “Number” field and decrements it by a numeric value passed along with the operator.

To use the API Request, you will need to authenticate yourself either with a Management Token (highly recommended) or an Authtoken.
Read more about it in Authentication.

For more information, refer to the SUB Operation API Reference document
