Upgrade your integration

Adyen aims to offer seamless integration for an easy checkout and payment process to shoppers globally. Because the payments industry is constantly changing, we frequently release new versions and features.

We recommend that you update your integration regularly to benefit from our latest improvements. Our updates provide competitive advantages so that your shoppers have an efficient checkout experience.

We frequently release improvements to our products to keep up with the newest developments in the fast-paced payments industry:

• Shopper expectations
• Regulations
• Best practices

Our way of versioning

Check our release notes to see the latest changes and follow our migration guides to upgrade your integration.

For our Drop-in/Components, we frequently release minor versions and periodically release major versions.
For our Checkout API, we only release major versions.

Drop-in/Components lifecycle

After a new Drop-in/Components version is released, it follows a lifecycle that contains four states.

Check the lifecycle states of our Web Drop-in/Components versions on GitHub.

The following is a visual example of how different versions receive new states over time:

Benefits of upgrading

You can get the best of Adyen's products when you upgrade your existing integration to a newer version. We recommend the following:

Upgrading from Classic API to Checkout API

We no longer develop the Classic API, which can process only card payments.

We strongly recommend that you upgrade your server-side integration to use the latest version of the Checkout API for the following benefits:

• A single integration to process all payment methods, including cards, bank-based, and alternative payment methods.
• A simpler client-side integration with Drop-in/Components that is only available with the Checkout API.
• Improved 3D Secure 2 authentication for payments. This includes simpler integration and the auto-authorization feature which reduces integration errors and failed payments.
• An integration that adheres to latest security standards, like JSON Web Encryption (JWE) and JSON Web Signature (JWS), and offers your shoppers a more secure checkout process.
• A simple, developer-friendly integration experience that handles many of the complexities of processing payments with less code complexity.
• More specific error responses that makes debugging easier.

Upgrading to the latest version of Checkout API

If you already use Checkout API, we recommend that you upgrade to the latest version of Checkout API if the following applies to you:

• You use 3D Secure 2 to authenticate payments with Adyen and use v66 or earlier. In v67, we simplified the integration and introduced auto-authorization that reduces integration errors and failed payments.
• You are are upgrading Drop-in/Components to a version that is no longer compatible with the your current Checkout API version. For example, Web Drop-in/Components v5.0.0 is only compatible with Checkout API v68 or later.

We continuously release new features for Checkout API to improve your online payments integration. Most improvements are backward compatible. When we must introduce a breaking change, we release a new major version.

Upgrading to the latest version of Drop-in/Components

Drop-in/Components follow the semantic versioning standard. Changes are released in a new patch, minor, or major version.

We recommend you upgrade to the latest major version of Drop-in/Components to get the latest features and bug fixes. The breaking changes introduced in our major versions improve performance of the integration and developer experience. Adyen no longer updates earlier major versions.

When you upgrade to the latest major version, you get the following:

• New payment methods
• New accessibility features
• Design improvements
• Better technical support
