Authorize and capture

To authorize and capture a transaction using the API, follow the steps below:

1. Configure Your Account

   Contact Integrations Support to ensure your merchant ID and account have access to the proper API endpoint.
   (You may be asked to provide additional information such as Gateway, TokenEx, or Kount credentials.)

2. Save a Card Token

   You may save a card token with your own form, with the save card token iframe or directly through the API. Card tokens can be used to process through any MID on your account. They are not restricted to a specific merchant account or currency.

3. Post Payment Information to Nexio

   Post payment details along with the card token to the Run card transaction endpoint.

   Example Request
