If you are using Stripe to manage payments for your membership site, you can leverage Stripe’s API to build advanced payment workflows. This could include handling failed payments, issuing refunds, or upgrading subscriptions.

Example: Automating Failed Payment Retries with Stripe

Steps:

1. Set Up a Webhook for Failed Payments:
   • In your Stripe dashboard, create a Webhook that listens for payment events such as invoice.payment_failed.
   • Set the webhook to send a notification to a custom handler URL (for example, https://your-site.com/stripe-webhook).
2. Handle the Webhook in WordPress:
   • In your WordPress installation, create a custom plugin or use the same one from earlier to handle Stripe webhook events: add_action('rest_api_init', function() { register_rest_route('custom_mp/v1', '/stripe-webhook', array( 'methods' => 'POST', 'callback' => 'handle_stripe_webhook', 'permission_callback' => '__return_true', )); }); function handle_stripe_webhook(WP_REST_Request $request) { $body = json_decode($request->get_body(), true); if ($body['type'] == 'invoice.payment_failed') { $customer_id = $body['data']['object']['customer']; // Logic to retry payment or notify the member } return new WP_REST_Response('Webhook received', 200); }
3. Automate Payment Retry:
   • After receiving a failed payment event, you can use Stripe’s API to retry the payment: curl https://api.stripe.com/v1/invoices/inv_12345/pay \ -u sk_test_your_secret_key:
4. Notify the User:
   • If the retry succeeds, notify the member by email or via a message on their account page.

Customization:

• Automate Refunds: Use the Stripe API to automatically issue refunds for failed payments after multiple retries.
• Notify Admins: Set up notifications in Slack or email to alert site admins when payments fail or when retries succeed.
