Anyone knowledgeable in setting up the new wallet API on a website for creating addresses for deposits / forwarding?

I wouldn't recommend using Blockchain.info API personally , instead use Blocktrail (also known as btc.com now) since they have better limits and more stable API.
If you insist on using Blockchain then you could find everything about this on their documentations https://blockchain.info/api/ (Specifically this as you want to generate new addresses and receive payments : https://blockchain.info/api/api_receive )

Getting blockchain api key is now hard these days so i used block.io before and also coded bitcoin receiving platform for few of my clients. You can find their api documentation here https://block.io/api/simple/php
but their limitation for free package is not useful if you need to generate huge number of addresses a day.

Instead you can try blocktrail api, however i haven't worked on their api but they seem to provide so much even for free package.

I've used the blockchain.info API multiple times in the past, it's documented well and is pretty self-explanatory. The API has frequent downtimes, however.

Just install their API lib (I use python, so it falls under pip install), initialise it in your code (in my case, import blockchain or whatever), and then simply use it in your code!
