Tokenization
Card details must be recorded via loading a minimally intrusive and unstyled iframe. Card details cannot be submitted via normal API.
<iframe 
  id="qex-card-capture"
  src="https://partners.liquid.com/api/v1/method/card/{settlement_instruction_id}" 
  />
<script>
    window.addEventListener('message', (event) => {
      const data: CustomPostMessage = event.data;
      if (data !== undefined && data !== null && data.event !== undefined) {
        switch (data.event) {
          case 'success':
            console.log('Tokenization Success', data.payload);
            break;
          case 'failure':
            console.log('Tokenization Failed', data.payload );
            break;
          case '3ds-frame':
            console.log('Must render 3DS iframe', data.payload)
            break
          case 'card-validation':
            console.log('Card validation updated', data.payload);
            break;
        }
      }
    }, false);
    const iframe = document.getElementById('qex-card-capture');
    const initializePostMessage = {
      event: "initialize"
    };
    iframe.contentWindow.postMessage(initializePostMessage, "*");
</script>
The initialize postMessage is essential to loading the iframe. It can contain a payload attribute which specifies some optional custom parameters for the input form.
const initializePostMessage = {
  event: "initialize",
  payload: {
    style: {
      base: {
        color: "#FFF",
        fontSize: "15px",
      },
      placeholder: {
        base: {
          color: "#aaaaaa",
        },
      },
    };
    localization: {
      card_number: 'Card Number' ,
      card_month: 'MM',
      card_year: 'YY',
      card_cvv: 'CVV'
    },
  },
};
See swagger documentation: https://partners.liquid.com/swagger/#/default/get_api_v1_method_card__settlement_instruction_id_​
Submit
The host application must render a "submit" button and call a submit post message when the user clicks it. This post message can optionally contain a payload which holds cardHolder information. This information is not always required, however some card issuers will reject transactions where it is not present.
const cardholder = {
  name: userInfo.fullName,
  billingAddress: userInfo.billingAddress,
  phone: userInfo.phoneNumber,
};
const submitMessage: CustomPostMessage = {
  event: "submit",
  payload: { cardholder },
};
iframe.contentWindow.postMessage(submitMessage, "*");
3D Secure
Card issuers must support the 3D Secure standard. To process 3DS, a second iframe must be rendered. 
The address of this iframe must be obtained from the previous iframe. See 3ds-iframe postMessage in the code above.
When the user completes the 3DS the new iframe will fire either the success or failure event.
