Requirements

B2BinPay account
PHP >= 7.0
PHP extensions enabled: cURL, JSON

Composer Installation

The easiest way to install the B2BinPay API client is to require it with Composer through command-line:

    $ composer require noname9/api-php

or by editing composer.json:

    {
        "require": {
            "noname9/api-php": "^1.0"
        }
    }

Getting started

See example code with comments in public/index.php

Create Provider instance

Use the API key and secret to access your B2BinPay account:

$provider = new B2Binpay\Provider(
    'API_KEY',
    'API_SECRET'
);

Test Mode

In order to use testing sandbox, pass true as a third parameter for B2Binpay\Provider:

$provider = new B2Binpay\Provider(
    'API_KEY',
    'API_SECRET',
    true
);

Warning: Sandbox and main gateway have their own pairs of key and secret!

Create a bill

The payment currency is considered to match the currency of your wallet.

Create a new bill:

$bill = $provider->createBill(
    WALLET_ID,
    '0.00000001',
    'BTC',
    LIFETIME
);

where LIFETIME - number of seconds for payment page to live and WALLET_ID - your B2BinPay wallet id.

Now the bill id is available in the $bill->id property. You should store this id with your order.

After storing the bill id you can find an url to the payment page in the $bill->url property.

Finally, you can check bill status by requesting it using the stored id:

$billCheck = $provider->getBill($bill->id);

The bill status will be stored in $billCheck->status property.

Convert currency

You can get actual rates and convert supported currencies respecting your wallet's parameters.

Get rates for USD:

$rates = $provider->getRates('USD');

Convert currency using actual rates:

$amount = $provider->convertCurrency('100', 'USD', 'BTC', $rates);

Now you can provide $amount variable as a second parameter for createBill() method to set an accurate amount of cryptocurrency.

Add markup

You can add some markup to the existing amount.

Set 10% markup for current amount:

$amount = $provider->addMarkup($amount, 'BTC', 10);

Get your wallet's params

You can retrieve your wallet's params to find out actual currency and current amount:

$wallet = $provider->getWallet(WALLET_ID);

Now your wallet's currency alpha code is stored in the $wallet->currency->alpha parameter.

You can use it for createBill(), addMarkup() and convertCurrency() methods.

Callback

Once bill status changed, our server can send a callback to your configured Callback URL. Also, you can specify Tracking ID, which will return with the callback to identify the exact order. To do that provide additional parameters to createBill() method:

$bill = $provider->createBill(
    WALLET_ID,
    '0.00000001',
    'BTC',
    LIFETIME,
    TRACKING_ID,
    'https://my.callback.url/'
);

Warning: If specified, your Callback URL should return the message "OK" with status 200. Until that payment will not be considered complete!

header('HTTP/1.1 200 OK');
exit('OK');

Callback verification

You can verify Callback request headers by comparing it with the getAuthorization() method output:

if (empty($headers['Authorization']) || ($headers['Authorization'] !== $provider->getAuthorization())) {
    header('HTTP/1.1 401 Unauthorized');
    exit();
}

Callback body

Callback request will contain the following data:

{
    "data": {
        "id": ID,
        "url": URL_TO_BILL_PAGE,
        "address": BLOCKCHAIN_ADDRESS,
        "created": TIME,
        "expired": TIME|NULL,
        "status": BILL_STATUS,
        "tracking_id": TRACKING_ID,
        "amount": AMOUNT_MULTIPLIED_BY_TEN_IN_POW,
        "actual_amount": ALREADY_PAID_AMOUNT_MULTIPLIED_BY_TEN_IN_POW,
        "pow": POW,
        "message": MESSAGE
    }
}
