Authorize.net Requirements
Hortense Malovich
I need authorize.net integration for subscription payments, likely using CIM. The requirements are simple - recurring monthly payments, with a few different price points. Customer credit card info will be stored a authorize.net .
I know that your question is what lib is best .. well, it might be easiest just to implement your own little bit of ad-hoc request and response for your specific requirements rather than trying to trove through an api on top of an api.
Authorize.net is changing the SSL/TLS certificates that applications and websites use to communicate with our systems, moving from Entrust to DigiCert. This change will impact both browser-based and server-to-server interactions.
Authorize.net is in the process of implementing support for Visa, MasterCard, and Discover Card on File (COF) for Customer Initiated Transaction (CIT) and Merchant Initiated Transaction (MIT). Also, it is implementing the separate Purchase Returns Authorization (PRA) Mandates. This article provides the latest information and links to available resources. Note:
Visa, Mastercard, and Discover have set requirements for merchants storing customer payment credentials for potential future use. There are two types of transactions processed using stored credentials:
A Cardholder Initiated Transaction (CIT) is any transaction where the cardholder actively initiates a transaction. This can be paying online, in a store, over the phone or through a pay link/QR code, etc. In a Card on File transaction, the cardholder initiates a transaction, opting to pay using card information previously used and stored on file with the merchant.
A Merchant Initiated Transaction (MIT) is a payment initiated by a merchant without the cardholder. To do this, the cardholder must have previously given the merchant permission to store their card details for use in certain types of future payments. This means that an MIT can only happen after a cardholder has previously completed a CIT with the merchant. MITs can be split into two kinds of transactions:
For those merchants who are storing their customer payment data outside of their Authorize.net account, please see our API Reference and Developer Guides for more information on how you can update your integration for COF mandate compliance. Please work with your 3rd party service provider and/or developer to direct them to this documentation as needed.
The Visa, MasterCard, and Discover card brands now require real-time authorization for customer refunds. This validates the payment data in real-time and provides immediate feedback on the success or failure of the refund attempt.
This mandate ensures customer payment data is validated in real-time, similar to the original charge transaction request. Consequently, refund transactions may now be returned as declines. This can occur if the cardholder account is no longer active or valid, or for various other reasons. Cardholders may need to contact their issuers to identify and resolve these issues. You may need to find alternative ways to refund your customer if their issuer will not authorize the refund.
You don't need to do anything to comply. Authorize.net automatically performs the refund authorization at the time of submission. It's important to note that this mandate, also known as the Credit Authorization Mandate, is being implemented across various entities involved in the credit card authorization process. These include:
As card networks design the mandates and provide the compliance requirements to issuers and processors, readiness varies. This has led some issuers to decline refunds. Some issuers, like FDCO Host Capture, which has always performed real-time credit authorization, may see real-time refund declines. All other processors may encounter a Settlement Error with their daily batch. If you receive a Settlement Error for a refund transaction, please contact your Merchant Service Provider to explore your options for refunding your customer.
This MasterCard-specific "Digital Secure Remote Payment" (DSRP) mandate updates the original MasterCard cryptogram, from UCOF (Unscheduled Card-on-File), to add a new field specifically for Tokens (i.e., Apple Pay, Google Pay, full PAN tokenized transactions processed via a CreateTransactionRequest).
Authorize.net is currently working on compliance with this mandate. You don't need to do anything at this time. This may change depending on your processor and will be updated here once more information becomes available.

Underneath the covers, role-based authorization and claims-based authorization use a requirement, a requirement handler, and a preconfigured policy. These building blocks support the expression of authorization evaluations in code. The result is a richer, reusable, testable authorization structure.
If an authorization policy contains multiple authorization requirements, all requirements must pass in order for the policy evaluation to succeed. In other words, multiple authorization requirements added to a single authorization policy are treated on an AND basis.
An authorization handler is responsible for the evaluation of a requirement's properties. The authorization handler evaluates the requirements against a provided AuthorizationHandlerContext to determine if access is allowed.
A requirement can have multiple handlers. A handler may inherit AuthorizationHandler, where TRequirement is the requirement to be handled. Alternatively, a handler may implement IAuthorizationHandler directly to handle more than one type of requirement.
The preceding code determines if the current user principal has a date of birth claim that has been issued by a known and trusted Issuer. Authorization can't occur when the claim is missing, in which case a completed task is returned. When a claim is present, the user's age is calculated. If the user meets the minimum age defined by the requirement, authorization is considered successful. When authorization is successful, context.Succeed is invoked with the satisfied requirement as its sole parameter.
It's possible to bundle both a requirement and a handler into a single class implementing both IAuthorizationRequirement and IAuthorizationHandler. This bundling creates a tight coupling between the handler and requirement and is only recommended for simple requirements and handlers. Creating a class that implements both interfaces removes the need to register the handler in DI because of the built-in PassThroughAuthorizationHandler that allows requirements to handle themselves.
If a handler calls context.Succeed or context.Fail, all other handlers are still called. This allows requirements to produce side effects, such as logging, which takes place even if another handler has successfully validated or failed a requirement. When set to false, the InvokeHandlersAfterFailure property short-circuits the execution of handlers when context.Fail is called. InvokeHandlersAfterFailure defaults to true, in which case all handlers are called.
In cases where you want evaluation to be on an OR basis, implement multiple handlers for a single requirement. For example, Microsoft has doors that only open with key cards. If you leave your key card at home, the receptionist prints a temporary sticker and opens the door for you. In this scenario, you'd have a single requirement, BuildingEntry, but multiple handlers, each one examining a single requirement.
The HandleRequirementAsync method has two parameters: an AuthorizationHandlerContext and the TRequirement being handled. Frameworks such as MVC or SignalR are free to add any object to the Resource property on the AuthorizationHandlerContext to pass extra information.
When using endpoint routing, authorization is typically handled by the Authorization Middleware. In this case, the Resource property is an instance of HttpContext. The context can be used to access the current endpoint, which can be used to probe the underlying resource to which you're routing. For example:
With traditional routing, or when authorization happens as part of MVC's authorization filter, the value of Resource is an AuthorizationFilterContext instance. This property provides access to HttpContext, RouteData, and everything else provided by MVC and Razor Pages.
The use of the Resource property is framework-specific. Using information in the Resource property limits your authorization policies to particular frameworks. Cast the Resource property using the is keyword, and then confirm the cast has succeeded to ensure your code doesn't crash with an InvalidCastException when run on other frameworks:
The sample code on AspNetCore.Docs.Samples shows how to implement additional authorization requirements with an external authorization service. The sample Contoso.API project is secured with Azure AD. An additional authorization check from the Contoso.Security.API project returns a payload describing whether the Contoso.API client app can invoke the GetWeather API.
Under API permissions, add the AppRole as a permission and grant Admin consent. Note that in this setup, this app registration represents both the API and the client invoking the API. If you like, you can create two app registrations. If you are using this setup, be sure to only perform the API permissions, add AppRole as a permission step for only the client. Only the client app registration requires a client secret to be generated.
Run the solution and use cURL to invoke the API. You can add breakpoints in the Contoso.Security.API.SecurityPolicyController and observe the client Id is being passed in that is used to assert whether it is allowed to Get Weather.
Underneath the covers, role-based authorization and claims-based authorization use a requirement, a requirement handler, and a pre-configured policy. These building blocks support the expression of authorization evaluations in code. The result is a richer, reusable, testable authorization structure.
