[Back](./) # How can I add custom fields in hosted payment pages? You can add customer and invoice custom fields directly in your Hosted Payment Page template. For existing organizations, adding custom fields from [Hosted Payment Pages](/billing/help/settings/customisation/hosted-payment-pages.html#customfields) is currently in early access. This feature is enabled by default for organizations created after July 1, 2026. To enable it for your organization, contact our support team at [](mailto:support@zohobilling.com)[support@zohobilling.com](mailto:support@zohobilling.com). To do this: * Go to **Settings** > **Hosted Payment Pages**. * Edit the required template. * Open the **Order Details** tab. * Under **Account Information**, click **Add Field** under **Customer Custom Fields** to add customer custom fields. * Under **Additional Information**, click **Add Field** under **Invoice Custom Fields** to add invoice custom fields. * Choose the field type (**Optional**, **Mandatory**, **Hidden**, or **Read Only**) based on your requirement. * Click **Save**. If you want to prefill these fields through the Hosted Payment Page URL, use the custom field API field names as parameter placeholders. Learn more in [Prefill Customer and Invoice Custom Fields Using API Field Names](/billing/help/settings/customisation/pre-fill.html#prefill-customer-custom-fields-api).
