Authenticate requests using HTTP Basic Auth by adding a bearer token to the header, e.g. Authentication: Bearer {{access_token}}. You can get the {{access_token}} from the create token request.

Once a payment intent is processed i.e. payment is done using any payment type, it can’t be used again to perform another transaction.Each payment intent can be used for only one payment type.

Please follow the below structure for respective payment form where ccElement or ccMotoElement will be added. Here a custom css file has been added to support different card layout (i.e. single-line and multi-line).
