README

A PayPal REST API implementation.

Implemented functionality: Orders v2.

Resources

• Get started with PayPal REST APIs
• Test credit cards;

Storage

Structure

Both table names and field names can be customized.

Table order_payment

Fields to add to an existing table

• Mandatory: order_reference: implementation specific, eg. VARCHAR(45) NOT NULL,
• Mandatory: order_total: implementation specific, eg. DECIMAL(10,2) NOT NULL
• Optional: order_currency: CHAR(3) NOT NULL,
  • PayPal currency codes
• Mandatory: order_payment_status VARCHAR(45) DEFAULT NULL,
• Mandatory: payment_event_date_time DATETIME DEFAULT NULL,

New table example

CREATE TABLE order_payment (
    order_reference VARCHAR(45) NOT NULL,
    order_total DECIMAL(10,2) NOT NULL,
    order_currency CHAR(3) NOT NULL,
    order_payment_status VARCHAR(45) DEFAULT NULL,
    payment_event_date_time DATETIME DEFAULT NULL,
    PRIMARY KEY(order_reference)
) ENGINE = InnoDB DEFAULT CHARSET = utf8mb4 COLLATE = utf8mb4_unicode_ci;

Table payment_access_token

CREATE TABLE payment_access_token (
    token VARCHAR(100) NOT NULL,
    expire_date_time DATETIME NOT NULL,
    added_date_time TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,

    PRIMARY KEY(token)
) ENGINE = InnoDB DEFAULT CHARSET = utf8mb4 COLLATE = utf8mb4_unicode_ci;

Configuration

Use environment variables (check example configuration) (app url, default currency, table and fields names);

If not using order level currency, make sure to set the PAYMENT_DEFAULT_CURRENCY options, and leave blank PAYMENT_FIELD_NAME_ORDER_CURRENCY.

If using a very specialized setup and using the configuration is not enough, you can implement \WebServCo\Contract\Storage\Order\OrderPaymentStorageInterface specifically for your project.

Usage

An example is located in the directory public/payment.

Copy the files in your local project and adapt the paths.

Note: If a custom implementation is required, check and adapt the code located in src/example_implementation.

Testing the example implementation

• Create config/.env.ini;
• Fill paypal info
• Start project: ddev start
• Create tables;
• Create a test order:

INSERT INTO `order_payment` (order_reference, order_total, order_currency) VALUES ('Test1', 123.45, 'EUR');

• Open payment page: https://paypal.ddev.site/payment/pay.php?orderReference=Test1&languageCode=en

Note: languageCode is optional and only used internally in implementing project. If you set it when initialize the payment, it will arrive as parameter to the PAYMENT_RESULT_LOCATION and the PAYMENT_CANCEL_LOCATION.

TODO

[ ] Find a way to suppress Psalm "UnusedVariable" errors.

Not working (generates "UnusedPsalmSuppress" error):

/**
 * @psalm-suppress UnusedVariable
 */

/** @psalm-suppress UnusedVariable */
