Spreedly 3D2 Global Guide

Spreedly 3DS2 Global is currently in beta. Documentation and API usage are subject to change before final release. Please contact Spreedly support if you encounter any problems with your Spreedly 3DS2 Global integration.

Before getting started on your integration, please visit the Introduction to Spreedly 3DS2 Global guide for more information on the entities involved in a Spreedly 3DS2 Global transaction. To recap the steps needed:

  1. Create a Merchant Profile in your production Spreedly environment.
  2. Create a Spreedly SCA Provider on that Merchant Profile.
  3. For any transaction that should be 3DS2 authenticated, provide the SCA Provider key and all relevant device or browser info.
  4. Make sure your frontend is able to handle asynchronous 3DS2 flows.

Creating a Merchant Profile

To create a Merchant Profile that will hold your SCA Provider, you can make a request to the following endpoint. All fields shown below are required per card brand, but not all card brands are required.

Note: For information on how to obtain the Merchant Profile fields, please see our Merchant Profile Onboarding guide here.

Note: Mastercard does not offer auto-enrollment in order to register with 3DS1, manual enrollment is required. Please visit the Mastercard 3DS1 Manual Enrollment Guide for instructions on how to enroll.

Creating an SCA Provider

Using the Merchant Profile object created in the previous request, you can make a request to the following endpoint to build a Spreedly SCA Provider. Some things to note for this request:

  • There is currently only one type accepted: spreedly (case sensitive).
  • Spreedly highly recommends that new integrators start with a sandbox Spreedly SCA Provider to test their integration before trying their system in production. For more information on card values and scenarios to use with a Sandbox Spreedly SCA Provider, please see our Spreedly SCA Provider guide for details.
  • The merchant_password field is optional.

Using an SCA Provider On Gateway Transactions

The inclusion of an sca_provider_key on an authorize or purchase transaction tells Spreedly to perform a 3DS2 authentication with that provider before performing the gateway transaction. There are three possible outcomes for the initial message:

  1. The authentication succeeds without the need for a challenge. Spreedly will apply the authentication values to the gateway transaction and make a request to the gateway immediately. This is equivalent to supplying third-party 3DS2 values via the Third Party 3DS2 feature. Spreedly 3DS2 Global Successful Request
  2. The authentication fails immediately without the need for a challenge. In this case, Spreedly automatically fails the gateway transaction and will not reach out to the gateway. It is the Merchant’s responsibility to retry the transaction in the case of failure.
  3. The authentication requires a challenge and is put in a pending state. Once the user completes this challenge:
    • Spreedly will perform the gateway transaction in the case of success. If the authentication failed, Spreedly will fail the gateway transaction and it is up to the Merchant to try again if applicable.
    • Spreedly will perform a callback if a callback_url was provided in the transaction.
    • Spreedly’s Lifecycle object will emit an event that denotes that the transaction has completed.

It is also important to note that the sca_provider_key field is mutually exclusive with the attempt_3dsecure flag. The sca_provider_key is used to run 3DS2 authentication with a third party 3DS server and pass those results into the gateway. The attempt_3dsecure flag is used to run 3DS authentication on the gateway itself during the transaction.

In addition to the sca_provider_key, the Spreedly SCA Provider requires the IP address of a customer as well as a browser_info field for web or a device_info field for mobile. Information on collecting these fields can be found in our Spreedly 3DS2 Global Integration Guide for Web.

The response will look similar to other purchase and authorize requests with one key difference: there is now an sca_authentication object included in the response that details the state of the 3DS2 authentication. For a successful authentication, it will also show the 3DS2 (or 3DS1 if the transaction had to fallback) authentication information from the 3DS Server. These fields are passed into the gateway transaction automatically and shown here for informational purposes only.
