# Changelog ## [Week Ending 2026-07-10](https://docs.astrada.co/changelog/week-ending-2026-07-10) 7 days ago ### `transaction.created` + `transaction.updated` webhooks Added ## [Week Ending 2026-07-03](https://docs.astrada.co/changelog/week-ending-2026-07-03) 14 days ago 🚀 **Now live: Astrada Sandbox (GA)** — external testers can run the full enrollment → verification → transaction flow against a dedicated sandbox with test credentials, without touching production. Added ## [New header in Webhook delivery](https://docs.astrada.co/changelog/new-header-in-webhook-invocation) about 1 year ago We have added a new header `webhook-subaccount-id` to the HTTP request made on each Webhook delivery. The value is the `subaccountId` to which the event relates. Added ## [New field enrollmentGuidance returned by the SDK](https://docs.astrada.co/changelog/new-field-enrollmentguidance-returned-by-the-sdk) about 1 year ago We have added a new field to the `onSuccess` callback on card enrollment SDK. Added ## [New link on Card Subscription resource](https://docs.astrada.co/changelog/new-link-on-card-subscription-resource) about 1 year ago We've added a new link `networkBulkFeed` to the [Card Subscription](https://docs.astrada.co/reference/getcardsubscription) resource. Added ## [New field on Cardholder resource](https://docs.astrada.co/changelog/corporateid-new-field-on-cardholder-resource) about 1 year ago We've added a new field `corporate.id` to the [Cardholder](https://docs.astrada.co/reference/getcardholder) resource (only available for bulk-enrolled cards). On Smartdata cards, the value of the field maps to the "_CorporationNumber_" attribute of the "_CorporateEntity_". ## [Network bulk feed resource](https://docs.astrada.co/changelog/network-bulk-feed-resource) over 1 year ago We have introduced a new resource to associate a network’s reference - like a MasterCard SmartData DeliveryID - to the subaccount. This will allow our customers to autonomously manage those associations.
