Paypal Sandbox developers handbook - paypal

We are developing a new feature to our website "Payment Service", I was going through the https://developer.paypal.com/ website though I have some sample codes I would like to know if there is a developers handbook for reference.
Also would like to know if there is an support for paypal once you sign up to "Sandbox" and implement the service.
Any recommendations are welcome. Thanks in Advance

How can i enable both services i.e., Direct Payment and Express Checkout on Paypal live US business account?

Recently I had implemented Recurring Payments API using the following payment methods:
Direct Payment
Express Checkout
All was working fine on Sandbox account. But on Live account when i enable one payment solution like Express Checkout then service for Direct Payment is disabled and vice-versa. How can i enable both above mentioned payment methods/solutions for Recurring Payments?
You are requested to go to the link below to upgrade your US PayPal account to the Pro account.

After that you are able to integrate Direct Payment for Recurring Payments.

Recurring Payment for Hosted Solution Payflow Edition

In the Website Payments Pro Hosted Solution Integration Guide (Payflow Edition) for UK document there are some errors described. One of the errors are:
31 'Error in adding the recurring profile'
But it this document does not state how can I add a recurring profile using the hosted solution. This is what I am looking for.
Thank you.
EDIT:
What I found interesting is that the other guide (non-PayFlow Edition) it says recurring payments are not supported by PayPal Pro Hosted Solution, but in this one there is no information about recurring payment.
Yes, Recurring Payments are not supported in Hosted Sole Solution.
You can use Recurring payments only if you have a PayPal Payments PRO account(which is available in US,UK and CA) else use Recurring Billing in Payflow(available in US,UK,AUS).
In the PayPal Payflow page it says that is available in US, CAN, AUS, New Zealand, but not in UK.

Paypal api - Adaptive Payments APP ID

I have 3 different websites that I want to use paypal Adaptive Payments for.
Auction
Marketplace
Funding
Do I need to set-up an new APP with paypal for each one? Or if I got one website approved can I use that APP ID on all my websites?
Also can anyone advise on how to get passed by paypal to get the APP ID, any good tips ?
Best way is to open a new APP at apps.paypal.com and the APP review team will guide you with your requirements as the APP approval depends on your business model and many other factors.
Adaptive payments was discontinued as of 01/12/2017 and PayPal Marketplace is the equivalent to adaptive payments.
You can learn more about the Marketplaces product on the PayPal Developer Portal: https://developer.paypal.com/docs/marketplaces/pp4mp/?mark=marketplaces
You can also register your interest for PayPal Marketplace via the link below -

Express checkout difference between Website payments standards and PayPal payments Pro

I have already implemented the PayPal recurring payment section using Express checkout in Website standard Payments. Now I am asked to implement the same recurring payment using Express check out in PayPal Pro. On checking the integration guide, I found that Express checkout steps are same in pro and Website Standards and the only difference i found is Direct Payment is only present in Pro.
Is my conclusion correct? Can I reuse the code i used for recurring in website payments using express checkout ?
Any help will be greatly appreciated
Thanks in advance

You are correct. Recurring Payments with Express Checkout will be the same regardless if you have Website Payments Standard or Website Payments Pro. It would only be different when setting up Recurring Payments for Website Payments Pro.

shopify does not supprt paypal website payment standard

I have a basic account with shopify and shopify is allowing me to choose from following paypal solutions
PayPal Website Payments Pro (UK)
PayPal Website Payments Pro (CA)
PayPal Payments Pro (US)
PayPal Payflow Link
PayPal Express Checkout
Is there a particular reason why shopify does not support "paypal website payment standard" ?
I am building an e-commerce solution for a client and am suggesting client to use "paypal website payment standard". Is this a not a favored solution for any reason?
The integration options for PayPal standard aren't as robust as the other PayPal integrations so Shopify does not support it. Any of the options that standard provided should be covered by the other paypal products; you should be able to get the same functionality.
Is there something in particular from PayPal standard that the client needs that the other services don't provide?
It is not about the functionality. It's about the monthly costs that is tied to other paypal plans. Paypal standard does not require any monthly fees. That's the difference and that is why we hope to actually use it on the website.
