Crypto Currency Indicator (API)
This page outlines the specification for the cryptocurrencyindicator field. This field acts as a flag to determine whether or not a transaction is for the purpose of purchasing crypto currency.

Requirement: Your merchant category code must be 6051.

Process overview
There are two methods that can be used to include the cryptocurrencyindicator field in requests submitted to the acquiring bank:
- Method 1: By assigning default values on your account:
Using this method, the cryptocurrencyindicator field is automatically included in transactions processed on your account, with no additional configuration required. To configure your account to use this method, contact our Support team, requesting that your site is set up with your preferred default cryptocurrencyindicator field value (this is described in greater detail below).
- Method 2: By manually including the cryptocurrencyindicator field in your requests:
Using this method allows you to specify different values on a request-by-request basis. To configure your account to use this method, update your requests using the specification provided below.
Submitting cryptocurrencyindicator in a request
You will need to update the payload submitted within your JWT to include an additional field, as shown below. Submitting the cryptocurrencyindicator in this way will always override any value stored on your account or inherited from a parent.
