How to create proxy by rest api endpoints in Apigee Edge Cloud Eval Org ?

[g-g-v1]

HI There,

1. Do we have any Rest Api that I can use to create and import the proxy(zip bundle) in Apigee Edge Cloud ?

2. And once imported/created the proxy how can I deploy that proxy to Test Env via rest api only ?

I found below POST rest api which is getting used when I upload the zip proxy bundle via Edge UI.

https://apigee.com/organizations/abcxyz-eval/apis?name=apiproxy&action=import&validate=true

1. How can I use above post api in my Code so that I will call this and create proxy programmatically ?
2. What Access token to pass?, will this access token will expire?
3. What query params or Form_data to pass ?
