Paypal Standard Payment Method - Shopping Cart - paypal

Sorry I am new. I was trying Paypal Shopping Cart function and i realize that in paypal sandbox cart it allows users to edit the quantity. How do i go about keeping track of these quantity, lets say in my website they keyed 2 for quantity but in the paypal shopping cart they changed it to 1.
Does it mean that it is not recommended to have own shopping cart and orders should be viewed at paypal website?
Many thanks!

Implement cart upload. Then you can upload a list of multiple items the customer selected on your site and customers won't be able to change the quantity after reaching PayPal.

how to process one or more items in PayPal shopping cart

I would like some recommendations about open source or other solutions for processing one or more items collected using PayPal's shopping cart button. Thanks.
At this point, I am researching, looking for possible solutions.
Logically, PayPal's "add to cart" and "view cart" buttons suggests I will be sending an array and they will be returning verifications for that array. If that is true, I can use Javascript to generate a page with the appropriate images and links to access the purchased items. I will focus on PayPal's articles about the shopping cart data.
Almost any ecommerce shopping cart ever made is compatible with PayPal Checkout, so you can essentially use anything that suits your other needs.
Start with searching the web or PayPal's Partner Directory

Using a hosted button with quantities for options

I would like to use Paypal in conjunction with a web form for selling conference tickets. Tickets will be available in various types and prices - standard, student, couple.
I would like users to be able to select a variety of tickets in one transaction - for example, two standard tickets and one student ticket.
Ideally I would have Paypal manage the inventory so that people can't make payments when tickets have run out. The limit on tickets is on the total; numbers within categories don't matter.
I can set up a ticket item on Paypal and limit it to the appropriate number, and I can set option prices. What I can't work out is how I send a request to Paypal with more than one "option + quantity" pair selected.
Any help gratefully received!
You would not be able to send more than one option + quantity pair over to PayPal with the standard add to cart or buy now buttons and have PayPal keep track of the inventory. Your best options would be either to set up the inventory on the PayPal side, and use add to cart buttons for each option + quantity.
Another option would be to use the cart upload method, where you pass over all the item details during checkout. This is similar to what 3rd party carts do. They keep track of what the buyer is adding to their cart, and then when they are ready to checkout they simply send all of the details over to PayPal in one POST. With this method, you would have to keep track of the inventory on your end though.

Adaptive payments and preapproved/recurring payments

I am in the process of implementing a solution where the user would buy a product using one of two options, either using Credit card or using PayPal. Now basically I would want that the if the user does not have any credits left in his account I charge their PayPal account with a certain amount of money. I am going to use Adaptive Payments for this and I will be using .NET.
Now I have some questions. Does anyone know whether this can be done?
And something else. If I am going to use Adaptive payments.. are adaptive payments more expensive from PayPal side?
Thanks
So just to make sure I follow, their account will have 'credits' to purchase things. They will select items, and check out paying with credits. If the item costs 10 credits and they only have 8, you will charge them the appropriate amount for 2 credits?
This doesnt need to be adaptive payments. All you need to do is edit your checkout flow to account for multiple payment methods (credits and cc or credits and paypal).
So the flow would be like:
Cust adds item to cart -> Cust checks out -> Cart determines if any money is due -> Cart presents new adjusted total (minus credits) to the merchant -> Cust selects payment method and pays.

PayPal "Subscription" add to cart, with tax and shipping

Is there any way to create a shopping cart through PayPal that allows shoppers to add subscriptions for multiple items into a shopping cart then check out all at once?
This is easily done with regularly priced items, but does not work with recurring subscription items. Tax and shipping also need to be added to the subscription (based on geographic location) because it is a physical product.
PayPal customer support and technical forums have been no help in solving this.
Subsequently if this is not possible with PayPal, does anyone have suggestions for another payment processor that could handle this task eg authorize.net?
The subscription buttons won't handle this. They can only handle a single subscription, for a single item, in each session.
I would suggest using Express Checkout. Using Express Checkout, you can charge the buyer for multiple items upfront, and set up a recurring payments profile at the same time.

Multiple shopping cart on single domain

I'm wondering is it possible to have multiple Paypal shopping cart in one domain/site?
Edited:
One website, has many businesses which also have many products.
Each business has it's own paypal account and hence cart.
Is it possible to hold 1+ such shopping carts on one website, and how can the session to be managed to store the items in the cart?
In short, yes. You can have multiple shopping carts, one for each business, or a shopping cart that handles multiple vendors. How you may implement it such a cart depends on your specific needs.
Here are some helpful links:
PayPal Adaptive Payments API
Adaptive payments handles payments between a sender of a payment and
one or more receivers of the payment. Senders and receivers can have
any PayPal account type. Senders and receivers are not required to
have PayPal accounts initially.

generating multiple store fronts.Each seller has their own
administrative area to manage their own products, orders, and
shipments. Buyers will be able to buy from one seller or multiple
sellers at a time.
