Due to the PHP [END OF LIFE](http://php.net/supported-versions.php) cycle. Composer -------- [](#composer) You can install the bindings via [Composer](http://getcomposer.org/). Add this to your `composer.json`: ``` { "require": { "payjp/payjp-php": "~1.0" } } ``` Then install via: ``` composer install ``` To use the bindings, use Composer's [autoload](https://getcomposer.org/doc/00-intro.md#autoloading): ``` require_once 'vendor/autoload.php'; ``` Manual Installation ------------------- [](#manual-installation) If you do not wish to use Composer, you can download the [latest release](https://github.com/payjp/payjp-php/releases). Then, to use the bindings, include the `init.php` file. ``` require_once '/path/to/payjp-php/init.php'; ``` Getting Started --------------- [](#getting-started) In advance, you need to get a token by [Checkout](https://pay.jp/docs/checkout) or [payjp.js](https://pay.jp/docs/payjs). ``` \Payjp\Payjp::setApiKey('sk_test_c62fade9d045b54cd76d7036'); $charge = \Payjp\Charge::create(array( 'card' => 'token_id_by_Checkout_or_payjp-js', 'amount' => 2000, 'currency' => 'jpy' )); echo $charge->amount; // 2000 ``` Documentation ------------- [](#documentation) - [Request Example](https://github.com/payjp/payjp-php/blob/master/RequestExample.md) - Please see our official [documentation](https://pay.jp/docs/started). Retry on HTTP Status Code 429 ----------------------------- [](#retry-on-http-status-code-429) - See [Rate Limit Guideline](https://pay.jp/docs/guideline-rate-limit#2-%E3%83%AA%E3%83%88%E3%83%A9%E3%82%A4) - When you exceeded rate-limit, you can retry request by setting `$maxRetry`like `\Payjp\Payjp::setMaxRetry(3);` . - The retry interval base value is `$retryInitialDelay`Adjust the value like `\Payjp\Payjp::setRetryInitialDelay(4);`The smaller is shorter. - The retry interval calcurating is based on "Exponential backoff with equal jitter" algorithm. See Logging ------- [](#logging) - This library provides simple log output using `error_log` . You can set any logger that is compatible [PSR-3](https://www.php-fig.org/psr/psr-3/) logger interface. Like below - `\Payjp\Payjp::setLogger($logger);` - As the default behavior, this library output only error level information to stderr. ### Logging Case [](#logging-case) #### info [](#info) - Every retry on HTTP Status Code 429 #### error [](#error) - When you access inaccessible or non-existing property Development ----------- [](#development) ### Running Tests [](#running-tests) In order to run tests first install [PHPUnit](http://packagist.org/packages/phpunit/phpunit) via [Composer](http://getcomposer.org/): ``` composer update --dev ``` To run the test suite: ``` ./vendor/bin/phpunit ``` You can also use Composer to run the tests: ``` composer test ``` This will run both the code style checks (PSR2) and the PHPUnit tests. ### Code Formatting [](#code-formatting) To format the code according to our standards: ``` composer fix ``` This command requires PHP 7.4 or higher and will automatically fix coding style issues using PHP-CS-Fixer. ### Health Score 54 — FairBetter than 97% of packages Maintenance48 Moderate activity, may be stable Popularity55 Moderate usage in the ecosystem Community31 Small or concentrated contributor base Maturity68 Established project with proven stability Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
