WebMoney

Component for miniShop2 that lets you accept order payments via WebMoney.

To start accepting payments:

• Register at WebMoney and get attestation not lower than formal; see here
• Create a wallet for the currency you want to accept and configure it for payments via Web Merchant Interface at merchant.webmoney.ru
• Install and configure the component
• Apply the needed changes on the site

Wallet setup for Web Merchant Interface

Only a few points are called out; the rest are self-explanatory:

• Secret Key is required for security; you can set your own or let the service generate it
• Secret Key X20 is not used
• Result URL: http://YOUR_SITE/assets/components/minishop2/payment/webmoney.php
• Enable Pass parameters in preliminary request
• Success URL and Fail URL can be left empty, but set Success URL method and Fail URL method to POST
• Enable Allow URLs passed in form
• Signature method — MD5
• Choose Test or Production mode

Remember to save.

Component setup

After the wallet is configured, configure the component to work with it. In the site manager go to system settings, namespace minishop2, filter by section WebMoney. Set ms_payment_wm_secret (secret key from the wallet settings) and ms_payment_wmid (wallet id). Set the resource ids for success and error pages (you can use the cart resource id). If you changed order statuses on the site, set the Paid (or equivalent) status id — it will be set on the order after successful payment.

Site setup

When all settings are done, make small changes on the site. To make the new payment method available, enable it and allow it for the delivery methods that should support WebMoney (in miniShop2 settings). To show the payment button after checkout, add a mspWebMoney snippet call to the chunk shown after order creation by msOrder (default tpl.msOrder.success). If you want separate success and error pages, create them; you can also use the cart — mspWebMoney supports different chunks at different payment stages (see the snippet description).

mspWebMoney snippet

The snippet builds the button to start payment and shows success or error messages. It accepts 3 parameters:

• successTpl — chunk shown on successful payment. Placeholder trans_no — WebMoney transaction id
• errorTpl — chunk shown on error
• tpl — chunk for the button. It is actually a form with many hidden fields; if you are not sure what each field does, only change the button itself.
