External Services

This plugin connects to the G Online SMS gateway to send SMS messages and check account balance. This is a third-party service operated by G Online Sites.

What data is sent and when

  • When sending an SMS — the recipient’s phone number, the message text, your Sender ID, and your API key are transmitted to the gateway. This happens every time an SMS is triggered (user registration, WooCommerce order status change, form submission, manual send, etc.).
  • When checking balance — only your API key is sent. This happens each time the plugin dashboard page is loaded.

No data is sent without your action

No data is ever transmitted unless you have entered a valid API key in the plugin settings. The plugin makes no external calls on the front end of your website.

FAQ

How do I enable SMS login 2FA?

Go to G Online SMS OTP / 2FA and enable « Login 2FA ». Users with a phone number stored in their profile (billing phone or phone meta) will be required to enter an SMS code after their password. Users without a stored phone number will log in normally.

How do I set up WooCommerce checkout phone verification?

Go to G Online SMS OTP / 2FA and enable « WooCommerce Checkout ». A « Send Verification Code » button will appear on the checkout page near the billing phone field. Customers must verify their number before placing an order.

What happens if a user fails the OTP code 3 times?

The code is invalidated after 3 failed attempts. The user must request a new code using the « Resend code » link.

Does OTP work for users without a phone number?

For login 2FA — users without a stored phone number will log in normally without being prompted for a code. For checkout and registration, a phone number is required for those features to work.

Where do I get an API key?

Register or log in at sms.gonlinesites.com/app and copy your API key from the dashboard.

How are phone numbers stored for users?

The plugin checks for a billing_phone user meta (set by WooCommerce), then a phone meta. We recommend using WooCommerce’s billing phone field for best results.

Does the plugin work without WooCommerce?

Yes. WooCommerce, Contact Form 7, and Gravity Forms integrations are loaded automatically only when those plugins are active. OTP login and registration verification work without WooCommerce.

How do I configure Contact Form 7 per-form messages?

In the CF7 form editor go to the Additional Settings tab and add:

g_online_sms_message: New enquiry from {your-name}
g_online_sms_user_message: Hi {your-name}, we received your message!
g_online_sms_to_user: your-phone

Both admin and user messages fire simultaneously on submission.

Is my API key stored securely?

Yes — your API key is stored in the WordPress options table (the same location as all other plugin settings) and is only transmitted to the SMS gateway when sending messages or checking your balance.
