If you are a minFraud Legacy customer, please see our What's New in minFraud Score, minFraud Insights, and minFraud Factors document for a summary of the changes.
To learn more about the minFraud services and to purchase credits, please visit the minFraud Overview page. To better understand the differences between each minFraud service, review our minFraud Service Comparison page and the API response body documentation.
The following APIs are developed and maintained by MaxMind. See our guide on developing for the community if you have questions about creating or sharing your own unofficial clients or integrations.
We provide a Dispositions API for use with Disposition setting from the Transaction Details page. Use this API to integrate with your order management system, payment processor, or other internal system so that manual review decisions made from the account portal are available within your own systems. For more information about setting dispositions from the account portal, please refer to the article on reviewing transactions on our knowledge base.
If you are using our minFraud transaction fraud detection service, we also encourage you to use our report transaction service. By reporting transactions, you can help us significantly increase the amount of fraud we can detect for you. We build custom machine learning models for each customer based on reported transactions. We also manually review many reported transactions to identify customizations and algorithmic improvements for each customer reporting feedback.
If there has not been a service disruption, we may be able to help you diagnose
your connection issues. Please use our

The minFraud Score, minFraud Insights, and minFraud Factors web services use two part versions. Our current release is version 2.0. The major version number will remain at 2 for the foreseeable future.
The minor version will only change if there are breaking changes in the web service. A breaking change is one that breaks client code that follows the documentation on this page. Breaking changes include changing the type of an existing field, deleting a field entirely, or changing URIs.
All changes to the web services will be documented in the minFraud release notes, whether or not the version number is changed.
The following changes are not considered to be breaking changes and will not be accompanied by a version number change:
- Increased validation of inputs that causes a warning to be returned when there previously was not one.
- Adding a new request or response field, either at the top level of the
structure or in one particular object such as the billing or
credit_card. Client code should be written to allow for new fields to appear.
- Adding new values to enum fields such as processor.
- Adding or removing warning or error codes, and/or changing the body type for
an error. Client code should always check the
Content-Typeheader for any error response. Client code should also be prepared to handle any valid HTTP 4xx or 5xx status code.
- Adding a new service with a new path.
