Before you begin

Three things you'll want in front of you before you start. The setup is much smoother when you don't have to leave mid-flow to chase a credential.

An active TBC E-commerce merchant contract. If you don't have one yet, sign up at tbcbank.ge → Business. Approval typically takes 3-5 business days.
Your TBC merchant API credentials: a merchantId and an apiKey. TBC sends these by email once your contract is live. Look for a message titled "TBC Acquiring — API access".
WordPress admin access to your store, and WooCommerce already installed and active. The plugin doesn't install WooCommerce for you; if you don't have it yet, install it from Plugins → Add New first.

Buy a TBC Card Payment license

Open the TBC Card product page and click Buy license. License is ₾160 / year per domain with a 14-day no-questions refund window.

Download the plugin ZIP

Install the plugin in WordPress

In your WordPress admin, go to Plugins → Add New → Upload Plugin. Select the ZIP you downloaded, click Install Now, then Activate Plugin.

WordPress admin: Plugins → Add New → Upload Plugin. Select the ZIP, then click Install Now.

Once activated, you'll see a new admin notice at the top of the screen prompting you for your license key. Click — it goes to the plugin's settings screen at .

Activate your license

On the plugin settings screen, paste your license key into the License key field and click Save changes.

Plug in your TBC merchant credentials

The TBC credentials section accepts merchantId and apiKey. You'll start with the sandbox / test credentials (the ones with the test_ prefix).

Field: merchantId: Your TBC merchant identifier. Looks like test_M00012345 for sandbox.
Field: apiKey: The API key TBC issued. 32+ character random string. Treat as a secret — never paste into public chats.
Mode: Toggle Sandbox / Production. Start in Sandbox; flip to Production in step 7 once your test order succeeds.

Place a 1-tetri test order

Open your storefront in an incognito window so you're not logged in as admin. Add any product to cart, drop the quantity / price down to a 1-tetri test value (you can do this from a hidden test product, or temporarily lower a real product's price), and proceed to checkout.

Switch to production credentials

Once your sandbox test passes, flip the Mode toggle to Production and replace the credentials with the production merchantId + apiKey TBC issued (the ones without the test_ prefix). Click Save changes — the green Connectedbadge should reappear, this time against TBC's production endpoint.

What your customers see

On your storefront checkout, the TBC Card option appears with the official TBC logo and the supported card network marks (Visa, Mastercard). Selecting it and placing the order takes the customer to TBC's hosted card-entry page — you never handle their card data, and you don't need PCI-DSS Level 1 certification.

Issuing a refund

From WooCommerce → Orders → [order] → Refund, enter the refund amount and click Refund via TBC Card. The plugin calls TBC's refund endpoint and updates the order status when TBC confirms.

Full refund:any time before the order is settled by TBC (typically next business day) — instant on the customer's card. After settlement, TBC processes it as a standard refund (3-5 business days back to the card).
Partial refund: supported. You can refund line items individually.
Refund decline: TBC rate-limits refunds per-card. If a refund declines with "decline general", wait until the next business day and try again — that's usually the cause. We have a dedicated note on TBC refund rate-limits (coming soon) in the troubleshooting page.

Common errors and what they mean

License domain limit reached: Your key is already bound to a domain. Disconnect the old domain from /licenses first, then re-activate on the new store.
License expired: Your 365-day term ended. Plugin keeps working through the 14-day grace window. Renew from /licenses — the same key continues to work after renewal.
TBC: invalid signature: The apiKey you pasted doesn't match the merchantId on TBC's side. Double-check you're using the matching test/test or production/production pair.
TBC: 3DS authentication failed: Customer cancelled or failed the 3-D Secure step on TBC's page. The order stays Pending — the customer can retry with a different card or bank.
