How to Set Up Your OxaPay Merchant Account in 5 Minutes

For most payment providers, creating a merchant account means filling out extra forms, waiting for approval, and going through lengthy verification steps. In OxaPay, merchant account setup process is completely different. Your OxaPay account is your merchant account. Once you sign up, you already have everything you need to start accepting crypto payments. All you need to do is configure your settings and, if required, generate a Merchant API Key to access advanced 商户服务.
This guide will show you how to get started in just five minutes.

Your Merchant Account = Your OxaPay Account

In traditional finance, a merchant account is separate from a user account. OxaPay simplifies the merchant account setup by making the account you create during registration automatically your merchant account.

• The account you create during registration is automatically your merchant account.
• You can manage your wallet, accept payments, and integrate business services all from the same dashboard.
• No KYC/KYB is required to activate merchant services.

👉 In short, there’s no need to open a separate merchant account, your regular OxaPay account is already merchant-ready.

After Signing Up

Once you log into the dashboard, the OxaPay merchant account setup becomes visible through the left-hand menu, where you’ll see all available services:

• 付款链接 和 Donation Service (no Merchant Key required)
• Merchant Service, 发票, 白标, 静态地址和 插件 (these require a 商户 API 密钥)
• 支付服务 (powered by 支付 API), POS和 发票机器人 (powered by your Merchant API Key)
• From here, you can decide whether you want a no-code solution like Payment Link or go further with advanced merchant services.

What Is a Merchant API Key and Who Needs It?

A Merchant API Key is a secure credential that connects your account with OxaPay’s merchant services.

• Is there a difference between an OxaPay account and a merchant account?

No. Every OxaPay user automatically has a merchant account.

• Do all users need a Merchant Key?

Not necessarily. If you only use Payment Link or Donation, you don’t need one.

But if you want to issue invoices, integrate plugins, use POS, or run white-label solutions, you must generate a Merchant API Key.
