We do have integration with Authorize.net as a merchant account provider, if you are processing through Infusionsoft: https://help.infusionsoft.com/userguides/sell-online/merchant-accounts/authorize.net-merchant-account
If not, we do have API endpoints that a developer could use to record manual transaction records. All of our documentation is available at: https://developer.infusionsoft.com
