Card link Moov Drop

The card link Drop enables Moov customers to register a user’s credit card in the most secure and seamless way possible.

With the moov-card-link element, credit card information is entered by the user and processed directly by Moov. All information is captured by an iframe and hidden from the customer’s website.

<script>
// Store a reference to the Moov Drop
const cardInput = document.querySelector('moov-card-link');

// Append required data to the Moov Drop
cardInput.oauthToken = "SERVER_GENERATED_TOKEN";
cardInput.accountID = "MOOV_ACCOUNT_ID";
cardInput.onSuccess = (result) => {
  /*
    Result is an object that contains the cardID. To advance to
    creating a transfer, send the cardID to your server-side
    integration to locate the generated paymentMethod to use
    in the transfer.
  */
  console.log(result);
};

// For example, submit the card data to Moov on form element submit
document.querySelector('form').addEventListener('submit' => {
  cardInput.submit();
});
</script>
Moov Drops require a secure HTTPS connection. If you don’t have a test environment with HTTPS enabled, we suggest setting up a hosting environment with ngrok, Netlify, or Vercel.
