PHP
Overview
The Circular Enterprise APIs provide a powerful and efficient way to certify data on the blockchain, ensuring immutability, transparency, and security. These APIs facilitate account management, network configuration, data signing, and transaction monitoring, making it easier for enterprises to integrate blockchain-based certification into their workflows.
This library is designed for developers who need to verify, sign, and submit data certificates using the Circular blockchain while maintaining seamless integration with PHP applications.
Installation
You can install the Circular Enterprise APIs via npm:
composer require circularprotocol/circular-enterprise-apis
Usage example
<?php
require_once __DIR__ . "/vendor/autoload.php"; // IF NEEDED
require_once __DIR__ . "/src/CircularEnterpriseAPIS-php"; // IF NEEDED
use Circularprotocol\Circularenterpriseapis\CEP_Account;
try {
// Instantiate the CEP Account class
$account = new CEP_Account();
echo "CEP_Account instantiated successfully.\n";
$address = "your-account-address";
$pk = "your-private-key"; // Note: pk should be a string, not a hex literal
$blockchain = "blockchain-address"; // Same here, string.
$txID = ""; // Initialize txID
$txBlock = ""; // Initialize txBlock
$account->setNetwork("testnet"); // chose between multiple networks such as testnet, devnet and mainnet
$account->setBlockchain($blockchain);
echo "Test variables set.\n";
if ($account->open($address)) {
echo "Account opened successfully.\n";
if ($account->updateAccount()) {
echo "Nonce: " . $account->Nonce . "\n";
$txIDTemp = $account->submitCertificate(
"your-data-to-certificate",
"1de4fc4d951349a382c9ca58e6c82feeed8a233657683455080338675ad7e61f"
);
if ($txIDTemp["Result"] == 200) {
$txID = $txIDTemp["Response"]["TxID"];
echo "TxID: " . $txID . "\n";
$resp = $account->getTransactionOutcome($txID, 10);
if ($resp["BlockID"]) {
$blockID = $resp["BlockID"];
$status = $account->getTransaction($blockID, $txID);
if ($status == 200) {
echo "Transaction Status: " .
$status["Response"]["Status"] .
"\n";
$account->close();
} else {
echo "Error on retrieving transaction";
}
} else {
echo "Error on retrieving transaction status";
}
} else {
echo "Certificate submission error";
}
} else {
echo "Update Account Error: " . $account->lastError . "\n";
}
} else {
echo "Failed to open account: " . $account->lastError . "\n";
}
} catch (Exception $e) {
echo "An error occurred: " . $e->getMessage() . "\n";
}
?>
