A Piso WiFi site should advertise GCash or Maya only when the installed vending platform or payment add-on explicitly supports the integration you are using. This page is an evaluation checklist; it does not assume that every Piso WiFi controller has a built-in GCash/Maya connector.

1. Verify that the platform actually supports the payment method

Start with the vending/controller vendor’s current documentation, supported add-on list, or API/payment-provider documentation. Confirm whether the integration uses a supported QR flow, API, merchant account, webhook/callback, wallet balance, or a separate third-party module. A generic captive portal that can display a QR image does not by itself prove automatic GCash or Maya session credit.

2. Define the exact payment-to-session mapping

Write down the expected mapping before testing: for example, which payment amount corresponds to which time/data package, whether fees are deducted, whether partial/over-payments are accepted, and whether a payment can credit more than one session. The controller should not rely on a customer-entered “I paid” button as proof of settlement.

3. Test success, delay, failure, and duplicate callbacks

Test Expected result
Successful payment One confirmed transaction creates exactly one intended session credit.
Delayed callback The portal stays pending and does not issue duplicate time while the payment provider is still confirming.
Failed/cancelled payment No paid session is credited.
Callback is delivered twice The integration treats the provider transaction ID idempotently and credits the customer only once.
Customer reconnects after payment The credited session remains tied to the controller’s documented account/session identity rather than being lost or duplicated.

4. Keep payment confirmation separate from Wi-Fi/network health

A customer can pay successfully while the controller has no upstream internet, and the network can be healthy while a payment callback fails. Keep those as separate status checks. If the portal receives confirmed payment but cannot start a session, investigate the controller’s payment/session logic. If the session starts but internet access fails, move to the dedicated DHCP/DNS/WAN troubleshooting guides instead of mixing network repair into the payment workflow.

5. Reconcile controller records with provider records

At the end of a test period, compare the payment provider’s transaction identifiers, amounts, statuses, timestamps, and refunds with the controller’s credited sessions. Differences should be explainable. Keep a process for correcting a paid-but-not-credited customer without manually exposing wallet credentials.

Security and privacy rules

  • Never ask customers for their GCash/Maya PIN, password, OTP, or recovery code.
  • Use the payment provider’s supported authentication/checkout flow rather than collecting wallet secrets in the captive portal.
  • Restrict API keys/webhook secrets to the server/controller component that actually needs them.
  • Do not place merchant secrets, transaction tokens, customer phone numbers, or account identifiers in public screenshots.
  • Log enough transaction metadata for reconciliation, but keep retention and access appropriate to the business and jurisdiction.

Go-live decision

Do not advertise automatic GCash/Maya acceptance until you can complete a small test matrix for success, failure, timeout, duplicate notification, reconnect, and refund/manual correction. If the installed platform has no documented integration, keep payment manual or use a supported provider/module rather than presenting a custom workaround as an official feature.

Useful next steps

Worked scenario: gcash maya payments

GCash and Maya Payments for Piso WiFi: Integration Checklist: do not infer a specific GCash/Maya integration from a generic Piso WiFi installation; check the current vending software/payment add-on.

Illustrative case: A payment confirmation arrives late after the customer retries. Reconcile transaction IDs and platform records before issuing duplicate credit; never request a wallet PIN or OTP.
