PPOM API endpoints

Good day, Dears,

My name is Teodora, and I am a backend developer. Me and my team are currently working on implementing some feature by using the PPOM plugin for WooCommerce system. The flow we want to implement is the following: First, we want to retrieve all the existing PPOM fields (globally, not for a particular product), and then to decide which field we want to set to a particular product. So, is there an endpoint to retrieve all the existing PPOM fields?

We would appreciate your answer.

Thanks in advance!
