# User Payment Pages

Once the payment has been initiated using `POST /payments`, your Merchant site must redirect the user’s browser to the following URI’s (depending on environment):

<table><thead><tr><th width="193">Environment</th><th>Payment Page Redirect URL</th></tr></thead><tbody><tr><td>Test</td><td>https://secure.staging.6dot50.com/payment?id=<code>paymentid</code></td></tr><tr><td>Production</td><td>https://secure.6dot50.com/payment?id=<code>paymentid</code></td></tr></tbody></table>

&#x20;Where `paymentid` is the unique PaymentID returned when initiating a payment using POST /payments.

Should the correct Payment ID be provided, a series of screens will be presented to the user to complete the payment.
