Setup Heleket

​

Prerequisites

• A Heleket account.
• A website URL for your store — Heleket verifies your domain and moderates the merchant before activating API access.

1

Create a merchant and get it approved

Heleket issues payment credentials per merchant, and a merchant must be approved before its keys work.

1. Log into Heleket and go to Business → Merchants.
2. Click Create merchant and give it a name.
3. Open the merchant’s Settings, click Leave a request, enter your website URL, and complete domain verification.
4. Wait for moderation — the payment key and Merchant ID become usable once the merchant is approved.

2

Copy your payment API key and Merchant ID

Once the merchant is approved, in its Settings tab:

1. Copy the API key for payments (regenerate it if needed).
2. Copy the Merchant ID (a UUID) shown in the same tab.

Don’t confuse this with the payout API key under your personal-account Settings → API (protected by 2FA) — that key is for withdrawals, not for accepting payments.

3

Connect Heleket in Komerza

1. In your dashboard, open Settings under Online Store, then go to Cryptocurrency.
2. Under Processors, find Heleket and click Connect.
3. Paste your API key and Merchant ID, then save.

Komerza automatically registers the payment webhook with Heleket — you don’t need to add a callback URL anywhere.

4

Route your coins to Heleket

On the Cryptocurrency page, open Coin routing and set each coin you want Heleket to handle to Heleket — or confirm default routing already points there.

5

Test the connection

Make a small test payment on your store to confirm Heleket processes it and the order is marked as paid before you go live.

​

How it works

1. A customer picks a Heleket-backed coin at checkout.
2. Heleket handles the payment and funds settle to your Heleket balance.
3. Heleket sends a webhook; Komerza validates it and marks the order paid, triggering delivery.
