Requirements

1. PHP 7.0 or higher.
2. PECL.
3. Composer.
4. A PassKit account; sign up for free at https://app.passkit.com.
5. Your SDK API credentials (Home >> Account >> Developer Tools >> Generate New SDK Credentials).

Installation

Instal & Enable the gRPC PHP extension

sudo pecl install grpc-1.42.0

After installing the gRPC extension, make sure the extension is enabled in your php.ini file, (e.g. /etc/php5/cli/php.ini, /etc/php5/apache2/php.ini, or /usr/local/etc/php/7.2/php.ini), depending on where your PHP installation is.

extension=grpc.so

For detailed steps visit the gRPC PHP quickstart.

Add bindings to composer

To install the bindings via Composer, add the following to composer.json:

{
  "repositories": [
    {
      "type": "git",
      "url": "https://github.com/passkit/passkit-php-grpc-sdk.git"
    }
  ],
  "require": {
    "passkit/passkit-php-grpc-sdk": "1.1.70"
  }
}

Then run composer install

Manual Installation

Clone the repo and include autoload.php:

require_once('/path/to/passkit-php-grpc-sdk/vendor/autoload.php');

Getting Started

Follow the installation procedure, and see general usage format & examples below.

Authorization

Simply request your SDK credentials from the PassKit Portal. You will receive an email with your credentials on your registered email address. Follow the instructions in the email to decrypt key.pem, and then copy the .pem files into your project (in this project & for the examples to work they should be in the certs directory).

You will need the credentials when you setup the SSL connection to the server.

Your credentials consist of 3 files:

• ca-chain.pem: the PassKit CA chain.
• certificate.pem: the certificate for your account.
• key.pem: the key that belongs to your certificate.

Setting up the connection:

putenv("GRPC_SSL_CIPHER_SUITES=HIGH+ECDSA");

$ca_filename = "ca-chain.pem";
$key_filename = "key.pem";
$cert_filename = "certificate.pem";
$path = "../certs/";

$credentials = Grpc\ChannelCredentials::createSsl(
    file_get_contents($path . $ca_filename),
    file_get_contents($path . $key_filename),
    file_get_contents($path . $cert_filename)
);

$client = new Members\MembersClient('grpc.pub1.passkit.io:443', [
    'credentials' => $credentials
]);

General Instructions

The general format is shown below. Each API has its own client that you will need to initialise. Clients can re-use the credentials object.

General format:

<?php
require_once "../vendor/autoload.php";

putenv("GRPC_SSL_CIPHER_SUITES=HIGH+ECDSA");

try {
    $ca_filename = "ca-chain.pem";
    $key_filename = "key.pem";
    $cert_filename = "certificate.pem";
    $path = "../certs/";

    $credentials = Grpc\ChannelCredentials::createSsl(
        file_get_contents($path . $ca_filename),
        file_get_contents($path . $key_filename),
        file_get_contents($path . $cert_filename)
    );

    $client = new Members\MembersClient('grpc.pub1.passkit.io:443', [
        'credentials' => $credentials
    ]);

    // Set the Member body
    $member = new Members\Member();
    $member->setProgramId("5fbCcr7f4NuBg9lvjJayvV");
    $member->setTierId("bronze");

    $person = new Io\Person();
    $person->setDisplayName("Patrick Kosterman");
    $dateOfBirth = new Io\Date();
    $dateOfBirth->setDay(22);
    $dateOfBirth->setMonth(6);
    $dateOfBirth->setYear(2020);
    $person->setDateOfBirth($dateOfBirth);
    $person->setEmailAddress("[email protected]");
    $member->setPerson($person);

    list($id, $status) = $client->enrolMember($member)->wait();
    if ($status->code !== 0) {
        throw new Exception(sprintf('Status Code: %s, Details: %s, Meta: %s', $status->code, $status->details, var_dump($status->metadata)));
    }

    echo "https://pub1.pskt.io/" . $id->getId();
} catch (Exception $e) {
    echo $e;
}
?>

Examples

The examples folder contains working samples for using the SDK.

To successfully run the program:

• ensure your gPRC certificates are in the certs folder in this repo (you will need ca-chain.pem, certificate.pem & key.pem).
• modify the variables with the values for your programs & campaigns.
• run cd examples && php enrol-member.php.

PassKit Portal

The https://app.passkit.com allows you to easily design loyalty cards, membership cards and coupons for both Apple Wallet and Google Pay.

Additionally, the PassKit portal facilitates management, distribution and simple analysis of your Mobile Wallet projects.

Best Practices:

• Use the web portal for initial account and project setup.
• Then use the SDKs / APIs to issue, update and delete your individual passes.

Members:

• Update Members by Segment: can be done by updating individual members and looping on client side
• Delete Members by Segment: can be done by deleting individual members and looping on client side
