Release Notes

Management API adds webhook HMAC rotation

Rotate a webhook's HMAC key without downtime: the previous key stays valid for 24 hours.

Call the generate HMAC endpoint on an existing webhook. Adyen signs notifications with both keys for 24 hours, so you can deploy the new key at your own pace.

Checkout API adds Pix Automático recurring payments

Charge Brazilian shoppers on a schedule with Pix Automático, using the same recurring flow as cards.

Checkout API v71 sessions flow improvements

The /sessions endpoint now returns the available payment methods in the same response.
