This plugin will allow you to generate a payment Reference the customer can then use to pay for his WooCommerce order in Kwanzas, through an ATM or Home Banking service.

This plugin works with the ProxyPay gateway, and a contract with an Angolan bank and TimeBoxed (the company behind ProxyPay) is required. Technical support is provided by Webdados.

Can I start receiving payments right away? Show me the money!

Nop! You have to sign a contract with ProxyPay and an Angolan bank in order to activate this service. Go to https://proxypay.co.ao/ for more information. They can help you out with all the subscription process with them and the bank.

[WPML] My website is multilingual. Will I be able to use this plugin?

Yes. This plugin is WPML compatible. You will need the WPML and WPML String Translation Plugins (alongside WooCommerce Multilingual, which is mandatory for any WooCommerce + WPML install).

[WPML] How can I translate the payment method title and description the client sees in the checkout page to secondary languages?

Go to WPML > String Translation > Search and translate the multicaixa_proxypay_gateway_title and multicaixa_proxypay_gateway_description, strings in the woocommerce domain. Don’t forget to check the “Translation is complete” checkbox and click “Save”. You should also translate the “Extra instructions” strings by searching the multicaixa_proxypay_extra_instructions string on the woo_multicaixa.

[SMS] How to include the Multicaixa payment instructions in the SMS sent by “WooCommerce – APG SMS Notifications”, “Twilio SMS Notifications” or “YITH WooCommerce SMS Notification”?

You’ll need the plugin PRO add-on.

[SMS] How to trigger the ProxyPay SMS system?

You’ll need the plugin PRO add-on.

[Advanced] The order is set “On Hold”, can I make it “Pending” by default?

I don’t know why on earth you would want to do this, but… yes, you can. Just return false to the multicaixa_proxypay_set_on_hold filter.
Be advised that no “new order” email, with payment instructions, will be sent to the client unless you use some plugin or custom code to force it.

[Advanced] Can I prevent the plugin from adding the payment instructions and/or the payment received message to emails?

You can use the multicaixa_proxypay_email_instructions_pending_send filter: return false and the payment instructions won’t be included in the “new order” email – we do not recommend you to do it, though.
You can use the multicaixa_proxypay_email_instructions_payment_received_send filter: return false and the payment received message won’t be included in the “processing” email.

[Advanced] How can I use the plugin with the ProxyPay sandbox, for tests?

You should return true to the multicaixa_proxypay_test_mode filter, or use the plugin PRO add-on to activate the test mode with a simple checkbox.

Can I contribute with a translation?

Sure. Go to GlotPress and help us out.

I need technical support. Who should I contact, ProxyPay or PT Woo Plugins (by Webdados)?
