Aras REST API - How do you navigate / create a BOM Structure using the REST API?

Hello Aras Community Members

Does the ARAS REST API allow you to navigate the BOM structure, starting with a Part? For example, if I have a BOM structure as shown below, I would like to start with any Part in the structure and navigate down the BOM tree. Can anyone share the REST API endpoint for making this work, or point to a specific section in the API guide?

Part A

- Part A1

- Part A2

--- Part A21

--- Part A22

------Part A221

Second question: Does the REST API allow users to create a BOM structure, e.g. a BOM tree as above?
