Endive

Endive is the fifth release in our flora-named API versioning model. As the first version in the Endive release, 2026-09-30.endive introduces both breaking changes and new features. Subsequent Endive versions will include only additive changes. (Our prior releases were Acacia, Basil, Clover, and Dahlia. Every time we introduce a breaking change version, we move to the next release.)

September 30, 2026

The September release of Endive includes these features and changes in our GA channel:

• Updated payment method configuration for Checkout and Elements: We removed the payment_method_types parameter from Checkout Sessions and removed the paymentMethodTypes option from Elements. For Checkout, use dynamic payment methods, allowed_payment_method_types, or excluded_payment_method_types instead. For Elements, use allowedPaymentMethodTypes or manage payment methods from the Dashboard.
• Thin events for API v1 resources: Thin events are now generally available for v1 API resources, making it easier to build forward-compatible webhook integrations with lightweight, version-independent event payloads.
• New payment method support: We added support for SeQura, a buy now, pay later payment method in Spain. We also now save Bancontact payment details in Checkout for future off-session SEPA Direct Debit payments.
• Billing improvements: You can now view proration details for classic billing mode Invoice Items, inspect invoicing rules on Invoice Items to see when items are eligible to be included on an invoice, and access uncollectible status details on the Invoice object to understand why an invoice was marked uncollectible.
• Payment Record on Payment Intents: We added the Payment Record property to the Payment Intent object, letting you retrieve the associated Payment Record directly from a Payment Intent without a separate lookup.
• Errors for eventually due Connect requirements: The Accounts, Persons, and Capabilities APIs now show errors for eventually due requirements. Previously, these APIs only included errors for requirements that were currently due or past due.

Our public preview channel also includes several updates:

• Payment Intent configuration on Checkout Sessions: When using Elements with Checkout Sessions in payment mode, you can now update Payment Intent configuration on an active session after creation, giving you more flexibility to adjust payment settings before your customer completes checkout.
• API evidence submission for eligible dispute appeals: You can now submit evidence through the API to appeal an eligible dispute decision, complementing the existing Dashboard workflow.
• Expired customer portal session recovery: We added session recovery for expired customer portal sessions, allowing your customers to resume a billing portal session after the link expires.
• Treasury Transaction IDs on Money Management events: We added a Treasury Transaction property to Money Management Transaction update events, making it easier to correlate Money Management activity with the underlying Treasury transactions.
