April 2021


Welcome to the Visa Developer April 2021 Release Notes that include key features introduced in this release.

Visa Crypto APIs:

The Visa Crypto APIs are intended to enable any eligible issuers to provide buying, selling, and custody of digital currencies (initially bitcoin) to their customers directly from their native digital products. The solution can give issuers the tools to attract new customers as well as increase engagement for their current base by offering crypto features that come without the heavy implementation lift. Visa intends for its Visa Crypto APIs to offer real-time price quotes, best-price order execution, and a secure ledger of assets that are built to work with any front-end user experience. For issuers looking to keep their crypto-minded users within their product ecosystem, these APIs could bring the capabilities they need and the confidence to scale with Visa as their trusted partner in the rapidly evolving space of crypto.

Note: This is currently rolled out as a restricted product in Sandbox only. If you are interested in using testing Visa Crypto APIs, please contact your sales representative or email [email protected].

Product Updates

Visa In-App Provisioning SDK

The Visa In-App Provisioning Software Development Kit (SDK) simplifies the technical integration requirements necessary to push consumer card credentials seamlessly from within a mobile app directly to Apple PayTM, Google PayTM and Samsung PayTM. The SDK provide a seamless, secure method for cardholders to pass their card details from the client’s mobile app to the wallet of their choice, eliminating the need to enter their card information separately.  For issuers and mobile app developers, the SDK improves speed to market, reduces expense, and removes the complexity of direct integration to multiple mobile wallets.

The Visa In-App Provisioning SDK can play a critical role in easily enabling digital provisioning flows for clients who are looking to support digital issuance use cases across the card account life cycle.

Use Cases

Partner Showcase - Keyno

Online Card Not Present (CNP) fraud is a major concern for card issuers today, and by using dCVV2 and the Keyno solution, dynamic data is introduced into the authorization message, which helps prevent fraud. Keyno is integrated with dCVV2, so with minimal effort card issuers can implement this powerful solution.

Refer to Keyno use case to see how Keyno used Visa’s dynamic CVV2 (dCVV2) APIs to provide a turnkey and easy to implement fraud prevention solution for Visa card issuers.

Platform Updates

Visa Developer Onboarding

Production onboarding is the final step to launch your solution. When you are ready, we will guide you through our onboarding workflow to help ensure that the end product meets our expectations before we provide access to our network.

While every solution is unique, each VDP API product has well-defined principles for onboarding acceptance. Some projects can move to production in as little as two weeks, while others may take multiple months. The onboarding schedule depends primarily on factors such as Sandbox readiness, API Product complexity, and commercialization prerequisites.  A firm estimate can only be provided after Visa understands your design and requirements. Once your solution is approved and available for your customers, we’re here to support you should issues arise in production.

Refer to Visa Developer Onboarding for more details.
