BitPay provides a standards-based REST interface which enables application developers to interact in a powerful, yet secure way bitcoin payout address example with apartment their BitPay account. Using the BitPay API, clients can create and manage invoices, issue refunds, manage bills, retrieve real-time rates information, view merchant ledger entries, and much more. Every Identity is represented in public form as a Bitcoin payout address example with apartment IDwhich much like the Bitcoin protocol, is simply a hash of the identity's public key.

For your convenience, all of BitPay's Client Libraries support this functionality. API Tokens are analagous bitcoin payout address example with apartment a real-world event ticket, which grants access to a specific event when presented at the door. Also like tickets, they may grant broad or narrow privileges e. New tokens are bitcoin payout address example with apartment with each response from the API.

For example, creating a new Invoice with one token will provide a new, second token that grants access to view and interact with that Invoice exclusively. If not using BitPay's Client Librariesyou will need to keep track of these tokens on your own. Facades named collections of capabilities that can be granted, such as the ability to create invoices or grant refunds.

In the ticket analogy, this corresponds to the ticket 'level', where a 'VIP' ticket would confer broader access than a 'Standard' level ticket.

When registering an Identity, it is against a specific facade. Best practices suggest that the requested facade should be limited to the minimum level that grants the required capabilities. To use any non-public facade a token will need to be sent with the API request. Tokens can require authentication, which would requiring cryptographically signing each request.

This will respond with a new token that will include a pairingCode. This pairing code can then be shared with a merchant organization administrator to approve access. A token without a Client ID authentication restriction can be made, and a token can then be copied directly to make API calls, such as creating invoices.

It is also important to note that pairing codes will expire after 24 hourshowever once a token is approved or claimed the expiration is cleared. Once again the mechanics of this exchange may be simplified through the use of one of the BitPay libraries.

For more information about specific resource URIs, please visit the resource documentation. So if you are sending a request to:. The result should be included as the value of the x-signature request header.

If your key becomes compromised, you will want to disable your old Client ID and register a new one. API sessions are an optional feature of our API which can be utilized to provide even greater security and reliability.

In particular it protects against replay attacks and ensures api requests are processed in the same order they are received. The server responds with a sessionId. The sessionId is used in each subsequent request along with a requestNumber. On the first request, the requestNumber should be 1. Each additional request should increment the requestNumber by 1. If the server receives a request out of order it will return an error. If the client does not hear back from the server because of an interruption in network connectivity or some other problem, the client may retry by sending the same request with the same requestNumber.

The server will then respond with a cached copy of the data if it had already serviced that request but was interrupted when delivering it to the client. API sessions timeout after 15 minutes of inactivity. After 15 minutes, clients will get an error, and must create a new bitcoin payout address example with apartment. Clients can be programmed to handle creation of new sessions and timeouts automatically.

Please see the Node. Codes marked as deprecated may have been used in the past, but are no longer used for newly written ledger entries. Bills are payment requests addressed to specific buyers. Bill line items have fixed prices, typically denominated in fiat currency. A client is identified by its access key id. A client is associated with a token via a pairing process. Invoices are time-sensitive payment requests addressed to specific buyers.

An invoice has a fixed price, typically denominated in fiat currency. It also has a BTC equivalent price, calculated by BitPay, with an expiration time of about 15 minutes. Retrieves invoices for the calling bitcoin payout address example with apartment filtered by query.

Payouts are batches of bitcoin payments to employees, customers, partners, etc. Rates are exchange rates, representing the number of fiat currency units equivalent bitcoin payout address example with apartment one BTC. Creates an API session to protect against replay attacks and ensure requests are received in the same order they are sent.

Settlements are transfers of payment profits from BitPay to bank accounts and bitcoin wallets owned by merchants, partners, etc. This endpoint exposes reports detailing these settlements.

Retrieves settlement reports for the calling merchant filtered by query. Gets a detailed reconciliation report of the activity within the settlement period. Subscriptions are repeat billing agreements with specific buyers. BitPay sends bill emails to buyers identified in active subscriptions according to the specified schedule. Tokens are API access identifiers which are associated with a set of capabilities.

A capability bitcoin payout address example with apartment be very broad, for example, retrieve the list of all exchange rates. Or a capability may be very specific, for example, update bill Overview BitPay provides a standards-based REST interface which enables application developers to interact in a powerful, yet secure way with their BitPay account.

Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. From a user perspective, Bitcoin is pretty much like cash for the Internet.

Bitcoin can also be seen as the most prominent triple entry bookkeeping system in existence. Bitcoin is the first implementation of a concept called "cryptocurrency", which was first described in by Wei Dai on the cypherpunks mailing list, suggesting the idea of a new form of money that uses cryptography to control its creation and transactions, rather than a central authority.

The first Bitcoin specification and proof of concept was published in in a cryptography mailing list by Satoshi Nakamoto. Satoshi left the project in late without revealing much about himself.

The community has since grown exponentially with many developers working on Bitcoin. Satoshi's anonymity often raised unjustified concerns, many of which are linked to misunderstanding of the open-source nature of Bitcoin. The Bitcoin protocol and software are published openly and any developer around the world can review the code or make their own modified version of the Bitcoin software. Just like current developers, Satoshi's influence was limited to the changes he made being adopted by others and therefore he did not control Bitcoin.

As such, the identity of Bitcoin's inventor is probably as relevant today as the identity of the person who invented paper. Nobody owns the Bitcoin network much like no one owns the technology behind email.

Bitcoin is controlled by all Bitcoin users around the world. While developers are improving the software, they can't force a change in the Bitcoin protocol because all users are free to choose what software and version they use. In order to stay compatible with each other, all users need to use software complying with the same rules. Bitcoin can only work correctly with a complete consensus among all users.

Therefore, all users and developers have a strong incentive to protect this consensus. From a user perspective, Bitcoin is nothing more than a mobile app or computer program that provides a personal Bitcoin wallet and allows a user to send and receive bitcoins with them. This is how Bitcoin works for most users. Behind the scenes, the Bitcoin network is sharing a public ledger called the "block chain".

This ledger contains every transaction ever processed, allowing a user's computer to verify the validity of each transaction.

The authenticity of each transaction is protected by digital signatures corresponding to the sending addresses, allowing all users to have full control over sending bitcoins from their own Bitcoin addresses. In addition, anyone can process transactions using the computing power of specialized hardware and earn a reward in bitcoins for this service. This is often called "mining". To learn more about Bitcoin, you can consult the dedicated page and the original paper.

There are a growing number of businesses and individuals using Bitcoin. This includes brick-and-mortar businesses like restaurants, apartments, and law firms, as well as popular online services such as Namecheap, Overstock. While Bitcoin remains a relatively new phenomenon, it is growing fast. At the end of April , the total value of all existing bitcoins exceeded 20 billion US dollars, with millions of dollars worth of bitcoins exchanged daily. While it may be possible to find individuals who wish to sell bitcoins in exchange for a credit card or PayPal payment, most exchanges do not allow funding via these payment methods.

This is due to cases where someone buys bitcoins with PayPal, and then reverses their half of the transaction. This is commonly referred to as a chargeback. Bitcoin payments are easier to make than debit or credit card purchases, and can be received without a merchant account.

Payments are made from a wallet application, either on your computer or smartphone, by entering the recipient's address, the payment amount, and pressing send.

To make it easier to enter a recipient's address, many wallets can obtain the address by scanning a QR code or touching two phones together with NFC technology. Much of the trust in Bitcoin comes from the fact that it requires no trust at all. Bitcoin is fully open-source and decentralized.

This means that anyone has access to the entire source code at any time. Any developer in the world can therefore verify exactly how Bitcoin works. All transactions and bitcoins issued into existence can be transparently consulted in real-time by anyone.

All payments can be made without reliance on a third party and the whole system is protected by heavily peer-reviewed cryptographic algorithms like those used for online banking. No organization or individual can control Bitcoin, and the network remains secure even if not all of its users can be trusted. You should never expect to get rich with Bitcoin or any emerging technology.

It is always important to be wary of anything that sounds too good to be true or disobeys basic economic rules. Bitcoin is a growing space of innovation and there are business opportunities that also include risks. There is no guarantee that Bitcoin will continue to grow even though it has developed at a very fast rate so far. Investing time and resources on anything related to Bitcoin requires entrepreneurship. There are various ways to make money with Bitcoin such as mining, speculation or running new businesses.

All of these methods are competitive and there is no guarantee of profit. It is up to each individual to make a proper evaluation of the costs and the risks involved in any such project. Bitcoin is as virtual as the credit cards and online banking networks people use everyday. Bitcoin can be used to pay online and in physical stores just like any other form of money. Bitcoins can also be exchanged in physical form such as the Denarium coins , but paying with a mobile phone usually remains more convenient.

Bitcoin balances are stored in a large distributed network, and they cannot be fraudulently altered by anybody. In other words, Bitcoin users have exclusive control over their funds and bitcoins cannot vanish just because they are virtual.

Bitcoin is designed to allow its users to send and receive payments with an acceptable level of privacy as well as any other form of money. However, Bitcoin is not anonymous and cannot offer the same level of privacy as cash. The use of Bitcoin leaves extensive public records. Various mechanisms exist to protect users' privacy, and more are in development.

However, there is still work to be done before these features are used correctly by most Bitcoin users. Some concerns have been raised that private transactions could be used for illegal purposes with Bitcoin. However, it is worth noting that Bitcoin will undoubtedly be subjected to similar regulations that are already in place inside existing financial systems.

Bitcoin cannot be more anonymous than cash and it is not likely to prevent criminal investigations from being conducted. Additionally, Bitcoin is also designed to prevent a large range of financial crimes.

When a user loses his wallet, it has the effect of removing money out of circulation. Lost bitcoins still remain in the block chain just like any other bitcoins. However, lost bitcoins remain dormant forever because there is no way for anybody to find the private key s that would allow them to be spent again.

Because of the law of supply and demand, when fewer bitcoins are available, the ones that are left will be in higher demand and increase in value to compensate. The Bitcoin network can already process a much higher number of transactions per second than it does today. It is, however, not entirely ready to scale to the level of major credit card networks. Work is underway to lift current limitations, and future requirements are well known. Since inception, every aspect of the Bitcoin network has been in a continuous process of maturation, optimization, and specialization, and it should be expected to remain that way for some years to come.

As traffic grows, more Bitcoin users may use lightweight clients, and full network nodes may become a more specialized service. For more details, see the Scalability page on the Wiki. To the best of our knowledge, Bitcoin has not been made illegal by legislation in most jurisdictions. However, some jurisdictions such as Argentina and Russia severely restrict or ban foreign currencies.

Other jurisdictions such as Thailand may limit the licensing of certain entities such as Bitcoin exchanges. Regulators from various jurisdictions are taking steps to provide individuals and businesses with rules on how to integrate this new technology with the formal, regulated financial system. Bitcoin is money, and money has always been used both for legal and illegal purposes.

Cash, credit cards and current banking systems widely surpass Bitcoin in terms of their use to finance crime. Bitcoin can bring significant innovation in payment systems and the benefits of such innovation are often considered to be far beyond their potential drawbacks. Bitcoin is designed to be a huge step forward in making money more secure and could also act as a significant protection against many forms of financial crime. For instance, bitcoins are completely impossible to counterfeit.

Users are in full control of their payments and cannot receive unapproved charges such as with credit card fraud. Bitcoin transactions are irreversible and immune to fraudulent chargebacks.

Bitcoin allows money to be secured against theft and loss using very strong and useful mechanisms such as backups, encryption, and multiple signatures. Some concerns have been raised that Bitcoin could be more attractive to criminals because it can be used to make private and irreversible payments. However, these features already exist with cash and wire transfer, which are widely used and well-established. The use of Bitcoin will undoubtedly be subjected to similar regulations that are already in place inside existing financial systems, and Bitcoin is not likely to prevent criminal investigations from being conducted.

In general, it is common for important breakthroughs to be perceived as being controversial before their benefits are well understood. The Internet is a good example among many others to illustrate this. The Bitcoin protocol itself cannot be modified without the cooperation of nearly all its users, who choose what software they use. Attempting to assign special rights to a local authority in the rules of the global Bitcoin network is not a practical possibility. Any rich organization could choose to invest in mining hardware to control half of the computing power of the network and become able to block or reverse recent transactions.

However, there is no guarantee that they could retain this power since this requires to invest as much than all other miners in the world. It is however possible to regulate the use of Bitcoin in a similar way to any other instrument. Just like the dollar, Bitcoin can be used for a wide variety of purposes, some of which can be considered legitimate or not as per each jurisdiction's laws.

In this regard, Bitcoin is no different than any other tool or resource and can be subjected to different regulations in each country.
