360Pay – Pagamentos por Carteiras Móveis para MasterStudy

360Pay adds a modular integration for mobile wallet payments directly inside the native MasterStudy LMS checkout.

This is an independent, third-party plugin. It is not affiliated with, endorsed by, or sponsored by MasterStudy LMS / StylemixThemes or by Vodacom / M-Pesa. “MasterStudy” and “M-Pesa” are trademarks of their respective owners and are used here only to describe the services this plugin integrates with.

The plugin is designed to:
* Keep orders in pending status until the API confirms the payment.
* Ensure all payment confirmations are verified server-side.
* Validate transaction reference, amount, currency, student, course, and payment status before granting access.
* Receive callbacks/webhooks through a secure REST API.
* Fallback to automated polling via WP-Cron.
* Support multiple mobile wallets, including M-Pesa, e-Mola, mKesh, or custom wallets configured manually.
* Never ask for PINs, OTPs, or private wallet data on the site.
* Keep detailed transaction logs without exposing credentials or sensitive info.

Technical details:
* Order post type: stm-orders.
* Native order items table: {$wpdb->prefix}stm_lms_order_items.
* Native enrollment function: stm_lms_add_user_course().
* Cart helper: stm_lms_get_cart_items().
* Action hook: stm_lms_purchase_action_done.

/wp-json/ms-wallet-payments/v1/callback/{wallet_slug}

Public Status Check URL:
/wp-json/ms-wallet-payments/v1/status/{transaction_reference}

Reprocess Callback (Admin only):
/wp-json/ms-wallet-payments/v1/reprocess/{transaction_reference}

Developer Hooks

You can customize checkout context, order creation, order completion, enrollment, and status checks using filters:

add_filter( 'mswp_masterstudy_checkout_context', function ( $context, WP_REST_Request $request ) { ... } );
add_filter( 'mswp_masterstudy_create_pending_order', function ( $order_id, $transaction ) { ... } );
add_filter( 'mswp_masterstudy_complete_order', function ( $completed, $transaction ) { ... } );
add_filter( 'mswp_masterstudy_enroll_user', function ( $enrolled, $transaction ) { ... } );
add_filter( 'mswp_masterstudy_mark_order_not_paid', function ( $updated, $transaction, $status ) { ... } );<h3>Fallback Shortcodes</h3>

If you need to manually integrate a checkout button for testing:
[mswp_wallet_checkout course_id=”123″ amount=”1500″ currency=”MZN”]

To display payment status:
[mswp_payment_status]

Security

• Access to courses is only granted after successful payment confirmation from the API.
• Duplicated callback/webhook requests are ignored.
• Webhook requests are validated with HMAC SHA-256 signatures if a webhook secret is defined.
• Sensitive keys and credentials are masked in the admin dashboard and logs.
• Direct SQL queries are sanitized using $wpdb->prepare and identifier escaping.
• Admin forms are secured with nonces and capability checks.

External services

This plugin connects to third-party mobile wallet payment APIs to initiate and verify payments. Card/PIN/OTP data is never handled by the site. The following external services may be contacted:

1. Vodacom M-Pesa Mozambique API (default provider)

• What it is and what it is used for: the official Vodacom M-Pesa Mozambique payment gateway. It is used to initiate a Customer-to-Business (C2B) USSD push payment request and to verify the resulting transaction status, so the plugin can release the purchased course only after the payment is confirmed server-side.
• What data is sent and when: the customer phone number (MSISDN), the transaction amount, the currency and a unique transaction reference are sent (a) when the student clicks “Pay” on the checkout page to start the payment, and (b) afterwards through automated polling / WP-Cron checks to update the payment status.
• Endpoints used: https://api.vm.co.mz:18352 (production) and https://api.sandbox.vm.co.mz:18352 (sandbox/testing).
• Terms of Service: https://www.vm.co.mz/artigo/termos-e-condicoes
• Privacy Policy: https://www.vm.co.mz/privacidade
• Developer portal: https://developer.mpesa.vm.co.mz/

1. Other mobile wallet APIs configured by the site administrator (optional)

• What it is and what it is used for: the plugin can also connect to other mobile wallet providers (for example e-Mola, mKesh or a custom wallet) only if the site administrator manually enables and configures them by entering the provider’s base URLs and credentials. They are used for the same purpose: initiating a payment request and verifying its status.
• What data is sent and when: the same data (phone number, amount, currency and transaction reference) is sent to the endpoint configured by the administrator, at the same moments described above.
• Terms of Service / Privacy Policy: these depend on the provider chosen and configured by the administrator, who is responsible for reviewing and complying with that provider’s terms and privacy policy before enabling it.
