API WooCommerce calculated custom field sync

[agencelarsen]

Hi, if anyone using Sendinblue/Brevo with WooCommerce has succeeded syncing custom fields in real time between both, I'm really interested.
I am using "Points and Rewards" and I would like Brevo/Sendinblue WC plugin to import the "user points balance" and "points balance value" fields that I have to calculate using a custom PHP function but I don't know how to hook such a function and map it with Brevo/SendInblue using the API.

Best regards
