Key points

What the buyer sees

The buyer picks card payment and goes to the payment page with the Clover fields.

What the admin gets

In the settings you enter the Merchant ID and keys, choose Sandbox or Live and check the connection.

How much it costs

The base version is free. Pro costs 1 290 UAH, a one-time payment for a lifetime licence.

The trial starts when you ask

A fresh install is the free version, nothing switches on by itself. The “Try Pro for 7 days” button → e-mail → the key right in the window and by e-mail.

One key — a site and a staging copy

Moving the site? Unlink the licence on the old domain and activate it on the new one yourself. A staging copy (staging., dev.) works with the same key and does not take a site slot. For studios — keys for 5 or 25 sites, or unlimited.

Technical requirements

  • OpenCart 4.0.2.0–4.1.0.3, 3.0.x or 2.3.0.2.
  • A Clover merchant account and Ecommerce API tokens.

Full module description

Clover Payments takes cards in OpenCart through the fields of Clover itself. The buyer types the card right at checkout, and the store gets only a one-time token. The module is for merchants who already have a Clover account.

We have not run a single payment through real Clover. Before you take money, run a test payment in the sandbox.

What the buyer sees

The buyer picks card payment and goes to the payment page with the Clover fields. If the bank declines, the buyer sees a clear message, the cart stays, and the order can be paid with another card.

What the admin gets

In the settings you enter the Merchant ID and keys, choose Sandbox or Live and check the connection. An order becomes paid only from an answer read from the Clover API.

How it works, step by step

  1. The buyer goes to the payment page and enters the card.
  2. Clover returns a one-time token.
  3. The shop server sends the charge with an attempt key.
  4. The module reads the result from the API and updates the order.
  5. If the answer is lost, the payment is searched in Clover without a new charge.

Under the hood

  • Card fields live in a Clover iframe, so the card number never reaches your server.
  • Each merchant keeps its own token.
  • A Hosted Checkout session cannot be closed from the shop: a buyer with two sessions can pay both, and the module shows that as a double.
  • The free version has no watchdog: a lost answer waits for a page check.

How to install

  1. Extensions → Installer: upload the archive for your version and keep the file name.
  2. OpenCart 2.3: the Installer copies files only with FTP enabled. Without FTP copy the contents of upload/ to the shop root by hand.
  3. OpenCart 2.3 and 3.x: Extensions → Modifications → Refresh.
  4. Extensions → Payments → Clover Payments → install button → Edit.
  5. Keep Sandbox, enter the Merchant ID and keys, check the connection.
  6. Run a test payment and only then switch to Live.
  7. For Pro: paste the key or start the 7-day trial.
