README

Coinpayments-IPN is a simple PHP package that lets you easily handle IPN requests from Coinpayments, without any hassle.

Disclaimer

At the moment, this package only supports the HTTP Auth IPN method in Coinpayments.

Usage

First of all, install the package via Composer:

composer require ronmelkhior/coinpayments-ipn

Then add in the IPN to your code like so:

<?php

use RonMelkhior\CoinpaymentsIPN\IPN;

$ipn = new IPN();

Once you initialize the IPN class, you need to setup the merchant ID & IPN secret with the setMerchantID and setIPNSecret methods.

<?php

use RonMelkhior\CoinpaymentsIPN\IPN;

$ipn = new IPN();
$ipn->setMerchantID('your-id-here')
    ->setIPNSecret('your-secret-here');

Then, you can validate the IPN with the validate method, which you need to provide your $_POST and $_SERVER arrays to.

<?php

use RonMelkhior\CoinpaymentsIPN\IPN;

$ipn = new IPN();
$ipn->setMerchantID('your-id-here')
    ->setIPNSecret('your-secret-here');

try {
    if ($ipn->validate($_POST, $_SERVER)) {
        // Payment was successful, verify vars such as the transaction ID/email and process it.
    } else {
        // IPN worked, but the payment is pending.
    }
} catch (RonMelkhior\CoinpaymentsIPN\Exceptions\InvalidRequestException $e) {
    // The IPN data was not valid to begin with (missing data, invalid IPN method).
} catch (RonMelkhior\CoinpaymentsIPN\Exceptions\InsufficientDataException $e) {
    // Sufficient data provided, but either the merchant ID or the IPN secret didn't match.
} catch (RonMelkhior\CoinpaymentsIPN\Exceptions\FailedPaymentException $e) {
    // IPN worked, but the payment has failed (PayPal refund/cancelled/timed out).
}
