HTML-form

An embedded cryptocurrency payment form on your website page.

The HTML form is a variant of the HTML widget in which the payment block is displayed directly on the page. The customer enters the amount, selects a currency and pays the invoice in an embedded window without leaving your website.

How to configure the form

  1. Open "My projects" → the relevant project → "Project settings" → "Payment widget".

  2. In the "Widget type" field, select "Form".

  3. Configure the parameters — changes are immediately visible in the preview window.

  4. Click "Save".

How to install the form on your website

  1. Copy the ready-made code below the preview window.

  2. Paste the code into the page HTML — where the form should be displayed.

  3. Publish the changes and open the page: the form should be displayed, and clicking the button should open the payment window.

How payment works for the customer

  1. The customer enters the amount (if it is not fixed) and, if required, an email.

  2. Clicks the payment button — an invoice is created in the embedded window.

  3. Selects a currency and network and sends a transfer using the payment details.

  4. After network confirmation, the invoice status changes to "Paid".

The payment window shows the project name, invoice number (INV), amount to pay and the invoice expiration timer. The approximate confirmation time is shown next to each network, and the customer can enable an email payment notification. After proceeding to payment, a QR code, the address and the exact transfer amount are shown, and the status can be checked with the transaction check button.

Payment notifications are delivered to the dashboard, by email and to Telegram, and with the "HTML widget (with postback)" method — via POSTBACK.
