Running a Transaction with a Token

It is important to use a referrer private API key to process the transactions. 

To submit a transaction with a token via the API you will need to add the token (which can be found on the customer’s profile page) to your POST request to the /txns endpoint. If the customer’s address information was saved then it will be automatically included when a Merchant submits a transaction using their token

Sample card payment and eCheck payment using a saved token:

Notes

• Do not use it in combination with Customer, since Customer is a unique token / card holder.

• When creating a tokenized card, this creates a unique Customer.
