Why accept cards online

Over 70% of online shoppers prefer to pay by card. If your website doesn't accept cards, you're losing most customers at the checkout stage.

Mulenpay lets you start accepting card payments in a single business day. This guide walks you through every step: from sign-up to your first live transaction.

Step 1. Registration and documents

Create an account at mulenpay.com and fill in your company details. You'll need:

  • Tax ID (INN) and registration certificate
  • Bank account details
  • Contact details of the responsible person

Review takes from 30 minutes to a few hours.

Step 2. Store setup

Once approved, create a store in the dashboard. Enter your website URL, callback addresses and success/failure page URLs.

Step 3. Test environment

Mulenpay provides a demo mode where you can test the entire payment cycle without real money. Use test cards from the documentation to verify successful and declined transactions.

Step 4. Integration

Choose your integration method:

  • Payment link — no coding required, great for small businesses
  • CMS plugin — for WordPress, OpenCart and other platforms
  • API — full customization for developers

Step 5. Go live

Switch your store to live mode and process your first real payment. Funds are settled to your bank account within the next business day.

The average time from sign-up to first payment among our clients is 4 hours.
