Use the PHP SDK

Applies to:Developers

Payabli offers a Software Development Kit (SDK) for the PHP programming language. The PHP SDK can be installed in your projects to support app development and provide type safety when programming with the API. Most development environments can use the SDK to generate code suggestions and inline documentation. See the payabli/payabli package for more information.

Dependencies

Before you begin, make sure you have the following installed on your machine:

PHP (8.1 or higher)
Composer
git

Use the SDK

This section shows you how to install and use the Payabli SDK in a new PHP project. The example code in this section shows how to use the SDK to make a transaction. It uses the moneyIn->getpaid method. The moneyIn->getpaid method calls the MoneyIn/getpaid endpoint.

Method names in the SDK correspond to endpoint names in the API reference. For example: the notification->addNotification method calls the POST Notification endpoint.

Create a new PHP project

Open your terminal and run the following commands to create a new PHP project:

$ mkdir my-payabli-app
> cd my-payabli-app

Install the SDK

Run the following command to install the Payabli SDK:

$ composer require payabli/payabli

Create a new file

Create a new file called index.php in the root of your my-payabli-app directory:

$ touch index.php

Open the index.php file in your code editor.

Make a transaction

The interactive walkthrough displays code examples alongside step-by-step explanations.

Follow the walkthrough to use the SDK in your PHP code.

/// Include autoloader and import client

Import the Payabli SDK to make it available in your code. This brings in the client class and type definitions you’ll need for payment processing.

1 <?php
2 // index.php
3 require_once __DIR__ . '/vendor/autoload.php';

5 use Payabli\PayabliClient;

/// Initialize the client

Create an authenticated client instance with your API key. The client handles all HTTP communication with the Payabli API and authorizes your requests. Store your API key securely and never commit it to version control.

1 <?php
2 // index.php
3 require_once __DIR__ . '/vendor/autoload.php';

/// Import request classes

Import the specific request and type classes needed for payment processing. These classes define the structure of your payment requests and responses.

41 
42 var_dump($result);

Run the app

Run the app with the following command:

$ php index.php

Check the result

Check the console output for the result of the transaction. A successful transaction returns output like this:

    array(4) {
        ["responseText"]=>
        string(7) "Success"
        ["isSuccess"]=>
        bool(true)
        ["pageIdentifier"]=>
        NULL
        ["responseData"]=>
        array(8) {
            ["authCode"]=>
            string(6) "TAS003"
            ["referenceId"]=>
            string(36) "255-67bc92c141e24f474f60c1968fcba0cd"
            ["resultCode"]=>
            int(1)
            ["resultText"]=>
            string(8) "Approved"
            ["avsResponseText"]=>
            string(35) "No Match, No address or ZIP match"
            ["cvvResponseText"]=>
            string(14) "CVV2/CVC2 match"
            ["customerId"]=>
            int(4440)
            ["methodReferenceId"]=>
            NULL
        }
    }

In production, we recommend that you pass a stored method ID to the paymentMethod object instead of card details. See more information in Tokenization Overview.

SDK example app

The SDK example app is a basic web app built with the Payabli PHP SDK. It demonstrates how to manage customers and use the temporary token flow with the SDK. The code is publicly available in the example repository.

Set up the app

Follow these steps to set up the SDK example app on your local machine:

Clone the repository

Open your terminal and run the following command to clone the SDK example app repository:

$ git clone https://github.com/payabli/examples

Navigate to the app directory

In your terminal, navigate to the directory containing the SDK example app:

$ cd examples/sdk/php-sdk

Install the dependencies

Install the dependencies with the following command:

$ composer install

Copy the environment template

Copy the.env.template file to a new file called .env:

$ cp .env.template .env

Fill in your environment variables

Open the .env file in your code editor. Set PAYABLI_KEY to a private API token, PAYABLI_ENTRY to your Payabli entrypoint, and PAYABLI_PUBLIC_TOKEN to a public API token:

$   # your Payabli Private API token
>   PAYABLI_KEY="o.Oim...Mekgjw="
>   # your Payabli entrypoint
>   PAYABLI_ENTRY="41xxxxxa7e"
>   # your Payabli Public API token
>   PAYABLI_PUBLIC_TOKEN="o.Oim...Mekgjw="

Start the development server

Run this command to start the development server, and open the app in your browser:

$ composer run serve

Use the app

The SDK example app has three pages:

Create Customer - Create a new customer in the Payabli entrypoint.
List Customers - View a list of all customers in the Payabli entrypoint.
Make Transaction - Make a transaction using the temporary token flow.

Create customer

The Create Customer page has a form that allows you to create a new customer. Fill in the form with the customer’s information and click the “Create” button. If the customer is created successfully, a green success message appears below the button.

List customers

The List Customers page has a table of all customers in the entrypoint. You can view the customer’s information, including their name, email address, and ZIP Code. Click the “X” button on the right side of a customer’s row to delete the customer. If the customer is deleted successfully, the row is removed from the table.

Make transaction

The Make Transaction page contains an EmbeddedMethod UI component using the temporary token flow. Fill in the form with payment information and click the “Process” button when the payment information is valid. The app performs these steps:

The embedded component saves the payment method as a temporary token and sends it to the server.
The server converts the temporary token to a permanent token with the POST TokenStorage/add endpoint.
The server uses the permanent token to make a transaction with the POST MoneyIn/getpaid endpoint.

If everything is successful, a green success message appears below the embedded component. See Extend embedded components with the temporary token flow for more information.

In the List Customers page, you can delete a customer by clicking the red “X” button on the right side of the customer’s row. If the customer is deleted successfully, the row is removed from the table.
