## Statements (checkable)
0. On API version 2026-09-30.endive the payment_method_types parameter is removed from the create Checkout Session method; passing it returns a 400 error.  [✓0 ✗0]
1. Replacements: dynamic payment methods (Dashboard), excluded_payment_method_types, or the new allowed_payment_method_types, which silently filters out incompatible methods instead of erroring.  [✓0 ✗0]

## Fix
```text
Remove payment_method_types from Checkout Session creation; use dynamic payment methods or allowed_payment_method_types. If you cannot change code yet, keep requests pinned to your previous API version (SDK version / Stripe-Version header).
```
