Start with your merchant account
Create a Trust Gateway account and complete the setup shown in your dashboard. Review the available subscription and connection requirements before sending a live payment request. Keep the account email and recovery method current so you can access transaction history when a customer needs help.
Connect the receiving account
Choose a supported merchant source and follow the connection steps in the dashboard. Confirm the receiving UPI ID carefully: a QR code is only useful when its payee information points to the account you intended. If you change receiving details later, create a new test request before sharing the next checkout link.
Create and verify the first request
Use a small payment request to check the entire journey. Open the checkout as a customer would, verify the displayed amount and payee, then watch the order in your dashboard. A pending page is not proof of payment. Fulfil the order only after its status is confirmed by the configured verification flow.
For a website or app integration, move on to the developer documentation after this manual check succeeds.
