Gate Pay has developed a dedicated white-label checkout terminal, and we also provide an on-chain payment address API to empower the underlying payment logic, allowing merchants to design their own checkout pages.
Step 1: Register a Gate account on the Gate App or the official website (https://www.gate.com/) and complete the KYB process.
This Gate account will be used to handle all operations and cash flow.
Step 2: Use the Gate UID obtained in Step 1 to register a merchant account here:
https://www.gate.com/pay-merchant
Fill in all required information as instructed.
Step 3: In the Merchant Dashboard, navigate to [Developer] - [App Configuration] to generate your API Key and Client ID.

Step 4: Integrating the White-Label Solution Option 1: White-label checkout terminal integration (this payment address is dynamic and will change with each order number).
Log in to the merchant dashboard, click [Settings Center] -- [Product Settings] -- [White-label Checkout Terminal], and enable white-label permissions. You’ll need to upload your [Brand Logo] and [Domain Suffix] to display your brand. Finally, click [Submit] and wait for approval.
Once approved, follow the API documentation to test your payment integration:
https://www.gate.com/docs/gatepay/common/en/
Please review the public documentation first and select the online service address (production environment) as your API test endpoint.
Integrate the white-label payment solution according to [Checkout Terminal Payment].
Option 2: White-label dynamic address integration (merchant designs the payment page front end).
Please follow the API documentation to test your payment integration: https://www.gate.com/docs/gatepay/common/en/ Review the public documentation first and select the online service address (production environment) as your API test endpoint.
Integrate the dynamic address payment solution according to [Address Payment]. The payment address will change with each order number, and the address bound to an order will be recycled after 7 days before binding to a new order. Users must transfer funds to the payment address within the order validity period to complete payment. If payment is made after the address is recycled, it may result in loss of funds. (SDK integration is available.) https://www.gate.com/docs/gatepay/address_payment/en/
Option 3: White-label static address. Integrate the static address payment solution according to [Address Payment — Static web3 Collection Code]. Static addresses (for high-volume, stable clients) can remain valid indefinitely. During the address validity period, users can continuously transfer funds to the address to complete orders.
