Features Documentation

Unique Features

BlockchainAPI was designed from the ground up to be the most easy-to-use Bitcoin payment system possible. No need to register an account, deal with external pages, or set up complicated API clients.

No Registration Required

No need to worry about getting a merchant application accepted or going through any tedious signup processes. Go ahead and get up and running now!

No Branding

No logos or external pages or branded buttons. Our API returns a simple JSON document for you to handle on your server however you would like.

Low Fees

In order to continue to keep our API online, we take a 1% commission. Other than this small commission and the 3.0E-5 BTC transaction fee, there are no other costs.

Safe and Secure

Our API and backend systems are secured with HTTPS and high-grade firewalls. Bitcoins are transferred to you ASAP, so there's nothing to worry about!

Bitcoin cash (BCH) support

We support bitcoin cash too, so you can offer your users two bitcoin versions to pay with!

Using the API

Making use of our API is extremely easy! Simply make a GET request to our API endpoint using the create method and receive a deposit address for your customer!

Configure your deposit system to call the following URL, replacing the value of the address parameter with your destination address and the value of the callback parameter with your server's callback URL:

copy 
https://blockchainapi.org/api/receive?method=create&address=1LisLsZd3bx8U1NYzpNHqpo8Q6UCXKMJ4z&callback=http://example.com/callback?invoice_id=1234

The customer's deposit address will be contained in the input_address property of the response.

copy 
{
    "fee_percent": 1,
    "destination": "1LisLsZd3bx8U1NYzpNHqpo8Q6UCXKMJ4z",
    "input_address": "1E2VSRsaW3Kb1gDkdRUGDo6knAKfi9iYsb",
    "callback_url": "http://example.com/callback?invoice_id=1234"
}

After a payment is made to the deposit address, we will forward the Bitcoin directly to the destination address you supplied and our server will send a callback GET request to your server that looks like this:

copy 
http://example.com/callback?invoice_id=1234&secret=7j0ap91o99cxj8k9&value=100000000&input_address=1E2VSRsaW3Kb1gDkdRUGDo6knAKfi9iYsb&confirmations=3&transaction_hash=0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098&input_transaction_hash=4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b&destination_address=1LisLsZd3bx8U1NYzpNHqpo8Q6UCXKMJ4z
