Simulating a card authorization

How can you simulate a card authorization (purchase) in the sandbox.

Suggest Edits

Overview

Because there is no actual money used in the accounts in the sandbox, we provide the ability to simulate a card authorization. This works in the same way that a purchase by a customer using their card would, but without you needing to use a genuine card and live data.

When you simulate the authorization of a card using the API, funds are removed from the card account. You can query this transaction using Retrieving transactions and Retrieving an account balance.

Simulating a card authorization

To simulate a card authorization, use the POST /simulate/authorization operation and provide parameters as shown in the table below.

ParameterTypeDescription
card_id
required		stringUnique ID that identifies the card.
amount
required		stringTransaction amount as a decimal string with two digits of precision, for example 45.50.
transaction_datetime
required		stringDate and time of transaction in the format YYYY-MM-DD HH:MM. For example, 2021-12-25 18:43.
currency
required		stringISO currency for the transaction, for example USD.
merchant_name
required		stringName of the merchant for the transaction.
merchant_city

merchant_zip_code
required		stringFive-digit US zip code, (for example 54234) or nine-digit US zip code, (for example 12345-1234).
Non-US state code between 2 and 20 characters.
mcc
required		stringFour-digit number that represents the type of services or goods that a business provides. For example 5732 represents electronics retailers.
mid
required		stringFour-digit numerical code that identifies a merchant to the purchaser, for example 7922.
