I would like guides and directions of where to start, resources I can use to understand the topic better. The deposit and withdraw system would be very similar to crypto exchanges where the user will have their own addresses to deposit different cryptos and can withdraw them.
Have you tried the BSV library. Albeit for safer non custodial wallets. But this does not mean to say you cannot integrate that with cloud apps.
It's done superbly by Handcash already.
There's excellent support docs and tutorials using live main and test net addresses at Satolearn and BSV Academy.

I have a requirement where I need to develop a web application in which two application users negotiate with each and later after agreeing on terms they are to trade illiquid bonds via Bloomberg. For this I need to generate the BXT and SXT Trade Tickets through my application. The question really is that is this even possible without the Terminal?
A white paper on Bloomberg API's website says
Other applications are possible, for example submissions of trade orders
But I am not able to find any reference or example how this can be achieved using Bloomberg API or any other service provided by Bloomberg.
I'd be surprised if you are able to do this, by definition a web application is hosted on server x and interacted with from device y. Bloomberg's entire business model is based around having a Bloomberg terminal on device y.
I'd recommend you look at other bond trading platforms not just Bloomberg, e.g. TradeWeb, MarketAxess or even the large brokers e.g. ICAP, Tullett who may have a more suitable API.
This might come a little bit late but you might want to have a look into Bloomberg's FIX API. I am working on a similar project and I have implemented this functionality in a web application that creates and sends Trade Tickets via FIX. You do not have to have a Bloomberg terminal installed. Your FIX session will connect directly to a Bloomberg FIX endpoint.
Bloomberg has a test environment for this. You have to contact one of their representatives and ask for a Beta FIX Session.
FIX is a publicly available protocol for exchanging financial information. A good starting point would be https://en.wikipedia.org/wiki/Financial_Information_eXchange
I need to use a bitcoin api, and only have found CoinBox. The problem is that coinbox is limited to only a few sites and isnt open to everyone so I cant use it. Are there any good alternatives to coinbox.me? Thanks.
There are actually quite a few apis. First there is coinbase which is my favorite since they pay the transaction fees for transactions over 0.001 BTC and all internal transactions are absolutely free (and instant). You can see their api. (https://coinbase.com/docs/api/overview). What they lack is that it is hard to grab the TX id's and any other specific information. There is also blockchain.info which is the most feature full, but the downside is that you have to pay all of the fees and it can get to be very expensive. You can see the api. (https://blockchain.info/api). There are a lot more but the problem is that they are very buggy. I hope this helps!
It is not necessary to use web wallets to create addresses. You can install your own bitcoin server/daemon and act like your own bank.
This is the place to start if you want to know how to do it (https://en.bitcoin.it/wiki/Main_Page).
Bitcoin can be queried using JSON RPC methods. So if you are running a bitcoin daemon locally you can just query them. The documentation for the same is located at
Running Bitcoin - https://en.bitcoin.it/wiki/Running_Bitcoin
API Reference - https://en.bitcoin.it/wiki/API_reference_(JSON-RPC)
API Call List - https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_calls_list
Hope this helps.
We are about to develop new mobile application that requires the end user to fill his payment information, which will be redirected to a third party’s portal to pay for a certain services through the application ( using Web Services )
user send billing information using web services , Is this legal for apple ?
It's OK to integrate 3rd party credit card payment systems in your app (for example PayPal, Amazon payments, etc. or your own system) as long as you do not sell services, extensions, etc. to your app. As you say you're going to sell physical goods, it is OK for Apple. Amazon app does the same thing. Btw it is even explicitly prohibited to use in-app payments to sell physical goods.
EDIT: more answer to the detailed questions in the comment
IMHO (see disclaimer):
Shipping fees of physical goods and signup fees for your physical service are NOT services or extensions - in the sense that Apple uses it, it applies only to some additional features to your application, for example a new level in a game or a new map in a mapping app
to be legally store, transmit, process credit card information, you will have to be compliant to the Payment Card Industry Data Security Standard. Here Apple has nothing to do, but both Visa and Mastercard (and maybe also other card issuers) require that you implement these practices if you wish to process credit card data of their cards
this last requirement might be tricky so I really suggest you to look for some ready solution instead of implementing your own. See also the first answer to this question: Use In App Purchase For Real Goods
DISCLAIMER: I am not a legal authority or somebody from Apple so I can give you just hints but not a legal advice - will have to ask a lawyer for an "official" answer :)
There are a number of free finance tracking sites out there like mint.com, wesabe.com etc.. .
I've tried all of them and all seem to miss the mark in one way or another. I'm interested in creating my own website, or possibly just a stand alone windows program for tracking my finances in ASP.NET or C#.NET.
I'm assuming the answer is no, but is there any way that a personal developer can download transactions from financial websites like these? I know once you login to most financial sites you can download a CSV or Quicken file. Yet I really like how I can log-in to my Mint.com account and update all my accounts with one click.
Popular applications (like Quicken) and most major US banks support Open Financial Exchange (OFX). If a bank can connect to Quicken, it probably supports OFX (though not guaranteed).
I doubt very many banks have public APIs for this. More likely than not, you will need to send HTTPS requests to the various banking websites, and you will probably have to have custom code for each bank that you wish to support, tailored to the structure of their websites and their form elements.
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.
