There are two ways to process a credit card:

1. ECOM (which usually requires 3DS)

ECOM payment is the default type and returns an acsform, which is a HTML from used to perform the 3DS authentication.

A HTML page should be send to the user which include the acsform in the body and the following JS in the header:

<script>
  onload = () => document.forms[0].submit();
</script>

The user will complete the 3DS form and submit.

After submission, the user will be returned to the predefined return URL with an encoded transaction ID.

2. MOTO (without 3DS).

MOTO payment processes the payment without the 3DS check. Once the payment is processed the user will be returned to the predefined return URL with an encoded transaction ID.
