Platform or API to allow purchasing and payment to owner - api

I am looking for the easiest platform or API to integrate into my site that would allow users to sell goods and get paid for them. I would, of course, take a small percentage of the payment. Hoping for something that is usable from python, though php would work too.

You need split payments. I think only Paypal currently offers that.

How to integrate PayPal into Aqbanking (HBCI)?

Since some time aqbanking supports paypal for hbci but I do not find any examples or documentation about that.
Does anyone can give me a legit example how to integrate paypal to download the current balance and also the last transactions like for any other bank supporting hbci?
If your version of AqBanking supports Paypal, it will appear in the list of protocols for a new user alongside HBCI, EBICS, OFX and offline. Many distributions, however, do not include support for Paypal.

How do I properly handle variable (creditted) amounts via PayPal APIs?

I'm looking for a way to allow our clients to do recurring payments to discount these payments based on the credit in their account which can be earned or deposited in many ways. For example, if they need to pay $20 and have $5 in credit, I would like to only bill the remaining $15 automatically without any need for additional website visits.
Looking at the documentation for PayPal's REST APIs, I don't see any clear way to do this. Is the only way to do this to send them a refund automatically? Or is there a way to get approved to bill clients up to X amount per month but allow us to bill under that amount. I thought billing agreements would allow for this, but after reading the documentation, I'm unable to figure out a way to do it. If it's possible, could someone walk me through what API calls would be needed to do this?
Thanks for any help you can offer.
There are a couple of different ways you could do this sort of thing, but I would avoid the REST API for now. It's still too new and doesn't provide as much functionality and features as the classic API.
Within the classic API, you can use either use Preapproved Payments, which consists of Preapproval and Pay APIs, or you could just use Express Checkout and/or Payments Pro with Reference Transactions.
Either way you'd basically be building your own recurring payments system where you'd setup a billing agreement and then your app would trigger the variable amount payments accordingly.

Personal Money Movement API

I'm trying to create a simple personal project: I want to give myself bounties for completing tasks that often fester on my todo list. If I complete a task, for example, $5 should automatically move out of my savings account into a discretionary spending debit card.
Are there any APIs or banks that have those APIs that could let me do that? All of the paypal APIs seem to charge a fee, which would be kind of silly if the money is simply moving between accounts. Any suggestions?
Most banks/organisations will charge I suspect as a vast amount of money made by these organisations is from transfer charges. I cannot think of free api that would let you do it.
However you could consider using another commercial organisation, say like Amazon, and perhaps use it's APIs to supply purchase with gift cards automatically? I'm not saying Amazon is free, I'm just using it as an example.
It's not quite what you want but may be acceptable.
it may not be pretty, but you can use curl to do transactions over https, provided your online bank uses standard html forms in some way, but it typicaly takes 3 processes
1. Login to get a token (user name and password will be required)
2. Use token to get a cookie (in some cases 1 and 2 are reversed)
3. use curl to post the form data for your transaction
There are some good pointers on using curl in similar ways here:

Marketplace payment processor

I'm building a marketplace application:
The customer pays the seller on the marketplace
The marketplace takes a cut of the payment
I would have a payment processing system with the following features
The cut and the 100%-cut are sent directly to the marketplace and seller accounts (ie, I don't want to have 100% on the marketplace account and then to forward the 100%-cut to the seller)
I would love to have a UI as much integrated with the marketplace website as possible. This implies that the customer in the worst case has to put only name, surname and credit card number on the payment processor interface (the ideal would be a payment interface totally integrated with our website)
I don't want to force the customer to register to any third party service
It should work nicely with Ruby on Rails
It should work for non US-based companies and should support multicurrency payments
What are the options out there?
Thanks.
I'd recommend you look at our product Balanced. It's built to solve exactly this problem so I think it's a good match.
At a high level payments in are done via credit card like a normal payment processor, funds are deposited into an escrow account which is a sum of all funds collected - all funds disbursed. When you're ready to push funds out you can currently pay out via next-day ACH (US only) but we're building out international support which sounds like it would be useful for you.
I believe it matches your other requirements:
there is no requirement to send users offsite, they do require accounts but you can create and edit them via the API.
Balanced has an excellent ruby gem
You can split up the payment, taking a cut from the proceeds as profit
Balanced provides you with a merchant dashboard for you and your customers to get a head start but you can build the exact same thing via API access.
One area where it's not going to meet your requirements is multi-currency charges. Currently you'll need to charge in USD and convert.
Check out https://github.com/drhenner/ror_ecommerce It doesn't have all the features you want but will give you a big head start.
Basically active merchant will connect to most gateways. You need to add the custom code. Look at the video for more help http://ror-e.com/info/videos/1

How can I do monthly subscription credit card billing?

I've written a subscription based web app that I want to charge (by credit card) a monthly fee. There are 3 different plans and once they sign up, they should be billed that amount, automatically, every month until they cancel. Is there an easy way to set this up (some sort of online service maybe?).
You can use Paypal's merchant service to provide reoccurring charges for a subscription.
Pretty easy to implement, they provide plenty of examples and even a sandbox to get you up and running.
There are now some service providers that take care of your billing and subscription needs. You use their API and they handle billing and subscriptions for you. Their services work with payment systems like PayPal and Authorize.Net.
Take a look at the following sites:
Chargify
Spreedly
Cheddargetter
I would suggest not using Paypal or Authorize's recurring payments directly. Their APIs are brutal, and the functionality is very rudimentary. It may work fine for when you're just starting out, but if you ever want to change anything down the line, you'll be in trouble.
I work for CheddarGetter, so I'm biased, but you should check us out.
Our competitors are not as robust or flexible, but they are definitely better than using Paypal or Authorize.net directly.
