Implementation Guidelines for Our Stripe PHP Webhook

  1. The Stripe PHP library is required to provide access to the Stripe API. Installation of the Stripe PHP library is easy via Composer. For example, run $ composer require stripe/stripe-php to install on a Linux web server.
  2. Consider how you will store and access your Stripe Secret API Key. In our example, we make use of the PHP dotenv library to load the Stripe Secret API Key as an environment variable from a .env file that resides outside of our web server's public folder. Installation of PHP dotenv is easy via Composer. For example, run $ composer require vlucas/phpdotenv to install on a Linux web server.
    Note: Alternately, hard-coding the secret key directly in the PHP Webhook would be ok for the Test Mode Secret Key of the Stripe Secret API Key but significantly risky for the Live Mode Secret Key.
  3. For binding the Stripe PHP and phpdotenv libraries within our PHP Webhook, we use Composer's autoload: require_once 'vendor/autoload.php';
    Note: Alternately, the Stripe PHP library may be loaded without Composer but you must manually install the library and ensure that your web server has the required Stripe PHP library dependencies ( curl, json, and mbstring). phpinfo() may be used to check the status of extensions.
  4. Add a Metadata key, value pair via the Stripe Dashboard for each product you would like delivered via email. The key is "product_email_filename" and the value is the filename of the product you would like delivered via email upon checkout completion. In the case of this product it is "StripePHPWebhookCode.pdf". This Metadata will be used by the Stripe PHP Webhook's sendMail() function for attaching the product's file.
  5. Configure the Stripe PHP Webhook for your implementation.
    1. Set the Sender Information within the following code block of the sendMail() function:
      // Sender Information
      $from = ' [email protected] ';
      $fromName = ' Sender Name or Company Name ';
    2. Set the Webhook Log File Location and File Name Format within the logWebhookStatus() function. For security, we place the log file outside of the web server's public folder. See the following code block:
      // Webhook log file location and naming convention
      $log_file_dir = $_SERVER["DOCUMENT_ROOT"] . " /../stripe-logs ";
      $log_file_name = $log_file_dir . " /log_ " . date("d-M-Y") . ".log";
    3. Ensure the loading of the required dependencies: Stripe PHP Library and PHP dotenv. For security, we installed the libraries outside of the web server's public folder. See the following code block:
      // Load the dependencies installed via Composer (Stripe PHP Library and PHP dotenv)
      require " ../stripe-lib/vendor/autoload.php ";
    4. Store your Stripe API Secret Key in a .env file outside the web server's public folder. In this example, we store the key in custom.env located in a folder named secret within the parent folder of your public folder. The custom.env file should initially contain the following entry:
      SECRET_KEY=" sk_test_...... "
      Note: This key may be later set to the "sk_live_......" Live Secret Key after completion of testing.
    5. Ensure the path is correct for loading the Stripe API Secret Key within the following code block:
      // Load the Stripe API Secret Key into the environment variable SECRET_KEY via PHP dotenv from custom.env that is outside the web server's public folder
      $dotenv = Dotenv\Dotenv::createImmutable(__DIR__ . " /../secret ", " custom.env ");
    6. Initialize the Stripe PHP Client with the API Secret Key stored as an environment variable. See the following code block:
      // Initialize the Stripe PHP Client with the API Secret Key stored as an environment variable
      $stripe = new \Stripe\StripeClient($_SERVER['SECRET_KEY']);
    7. Set the Stripe Webhook Signing Secret Key within the following code block:
      // Signing Secret Key for the Webhook
      $endpoint_secret = " whsec_...... ";
    8. Specify the path for products emailable as attachments. For security, we are using a folder outside of our web server's public folder. See the following code block:
      // Specify path to emailable products folder
      $path_emailable_products = $_SERVER["DOCUMENT_ROOT"] . " /../products-emailable/ ";
    9. Set the email signature for product deliveries within the following code block:
      // Construct the email signature
      $email_html_signature = ' <p>Best regards,<br />John Doe<br />Owner,<br /><br />555-555-5555</p> ' ;
    10. Create your Stripe Webhook Endpoint for testing.
      1. Sign in to the Stripe Dashboard.
      2. Click Developers button.
      3. Switch the Test mode setting to the On Position (lit in orange).
      4. Click the Webhooks tab under the Developers pageframe.
      5. Click the Add endpoint button.
      6. Helpful sample code is displayed in the right-hand pane.
        Note, the Listen to Stripe events page also displays information and settings regarding testing on a local server which will not be covered in this guide.
      7. Enter the Endpoint URL which should point to the test version of your PHP Webhook hosted on your server.
      8. Click the Select events button.
      9. Choose Payment Intent events.
      10. Mark the payment_intent.succeeded event.
      11. Click the Add events button.
      12. You should now have successfully created a Test Webhook Endpoint for the payment_intent.succeeded event.
    11. Please see Testing within the Stripe Docs for helpful information about Stripe Test mode and how to use test cards for the simulation of Stripe payments.
    12. Please Note: Within the Stripe Dashboard->Developers->Webhooks, you may click on a Hosted endpoint (webhook) and it will display a history of the associated events along with their status, date, time and data. The data is very useful for debugging. Most importantly, a Resend button is available which is extremely useful for testing and corrections.
