PayHere setup

PayHere is the most popular payment gateway in Sri Lanka. It accepts Visa, Mastercard, AMEX, and local bank cards. Setup takes about 10 minutes.

What you'll need

• A registered PayHere merchant account.
• Your business registration documents (PayHere will ask for verification).
• The domain your storefront runs on (for example, your-store.gannako.com or your custom domain).

Step 1 — Sign up with PayHere

1. Go to payhere.lk and create a merchant account.
2. Wait for PayHere to approve your account. They review your business and bank details — this usually takes 1-3 working days.

Step 2 — Register your domain

PayHere only accepts payments from domains it recognizes. You must register your domain before any payment will work.

1. Sign in to your PayHere dashboard at payhere.lk/account.
2. Click Settings → Domains & Credentials.
3. Click Add Domain and enter gannako.com. If you have already connected a custom domain to your store, use your custom domain instead (for example yourbrand.com).
4. Add a sandbox domain too if you want to test before going live.

Step 3 — Copy your credentials

1. Still on the Domains & Credentials page, find your Merchant ID at the top — copy it.
2. Below that, click Generate Merchant Secret (or reveal the existing one) and copy the secret.

Step 4 — Paste credentials into Gannako

1. In Gannako admin, open Settings → Payments → PayHere.
2. Click the API Credentials tab.
3. Paste your Merchant ID and Merchant Secret.
4. Click Save.
5. On the main payments page, toggle PayHere Enabled.

Step 5 — Test, then go live

1. Leave Test Mode on. Place a test order — PayHere shows a sandbox checkout where you can use any card.
2. Confirm the order moves to Paid in your admin dashboard.
3. Switch Test Mode off and run a real order (you can refund it after) to confirm live payments work.
