WooCommerce

There are two ways to run PeptidesPayment on WooCommerce. Most stores use the Payment Container, a card field inside your own checkout, installed as a plugin. You can also run the hosted checkout, the full PeptidesPayment checkout on a page you add to your theme.

Option A: Payment Container (plugin)

The plugin handles the cart, currency, tax, and webhooks for you. You do not send us amounts or write any webhook handling.

Taxes

When a buyer pays with the Payment Container, PeptidesPayment calculates the correct tax for the buyer's destination and the plugin charges it and shows it as a labeled Tax line — at checkout, on the order confirmation page, and in order emails. On plugin 1.2.2 and later this works even when WooCommerce's own tax calculation is turned off. On older plugin versions the tax is still charged, but the line only appears when WooCommerce taxes are enabled (WooCommerce → Settings → General → Enable taxes) — so keep WooCommerce taxes enabled or update the plugin. If your store calculates its own tax and PeptidesPayment has configured your account to use it, none of this applies: your own tax stays in place.

1. Install the plugin

You will need your Merchant ID and secret, and the plugin ZIP, from PeptidesPayment. In your WordPress admin, go to Plugins → Add New → Upload Plugin, choose the PeptidesPayment ZIP, and activate it. Open the PeptidesPayment settings and paste your Merchant ID and secret.

2. Test and go live

The card field appears on your WooCommerce checkout. Turn on test mode, place an international order with a test card, and confirm it appears in both WooCommerce and your PeptidesPayment dashboard. The plugin creates the WooCommerce order and keeps it in sync from PeptidesPayment's webhooks. Switch to live once the test passes.

Option B: Hosted checkout

To hand the whole checkout to PeptidesPayment instead, add a hosted checkout page to your store:

1. Add the PeptidesPayment checkout page template to your theme (a page template that renders the PeptidesPayment checkout iframe), provided by PeptidesPayment when your account is set up.
2. Create a WordPress Page that uses that template.
3. Route checkout to that page for the markets you want PeptidesPayment to handle.

Buyers complete the whole checkout on that page and return to your store once the order is placed. Contact your account manager to set this up.
