Information the client will supply:
store_id: store#
api_token: xxxxxxx
checkout_id: xxxxxxxxStore#
We do need to know if billing address needs to be supplied (AVS or other security options are enabled). That changes what we prompt for.
What they use for settings
Checkout type
We have developed against the selected option. 
Multi-Currency
Note the following. If multi-currency is enabled recurring billing, gift cards, 3-DSecure 1.0 and Google Pay and not supported.
Payment
Set the following perameters.
The payment security options
It's up to the client to enable these options or not. Note the issue about 3D Secure and Multi-currency above.
Transaction Type
Only development for purchase is coded for now.
We do not tokenize the card either so that stays off.
Branding and Design
The only setting think is important is setting "Enable Fullscreen" to Off.
Order Confirmation Settings
Email Communication Settings
