Upgrading Stripe Versions

Choose a target API version

If the user specifies a target API version, use it. Otherwise, look up the current version on docs.stripe.com with any documentation or web tool available to you, for example stripe docs /api/versioning with the Stripe CLI. The API versioning page states it in the sentence that begins “The current version is”.

Bundled fallback API version: 2026-08-26.dahlia. This value is only a snapshot from the last time this skill was generated, on 2026-09-27. Version identifiers start with their release date in YYYY-MM-DD format and new stable versions are released monthly, so a fallback version dated more than a month ago is probably stale. Use it only when you can’t reach docs.stripe.com. Never guess about a newer version number.

Before making changes, compare the target with each API version the integration pins: client configuration, per-request overrides, and webhook endpoints. Unless the user explicitly asks for it, don’t move any pin to an older version or a stable pin to a preview version. If a pin already matches the target, report it as unchanged. State the selected target and its source. If live verification fails or is unavailable, say that the latest version remains unverified, and don’t claim the integration is on the latest version.

When reviewing webhook endpoints and event destinations, distinguish snapshot events from thin events. Thin event payloads are unversioned, so they don’t need to be upgraded when you change your API version. API calls that retrieve the full event or related resource remain versioned.

For SDKs that support explicit API version overrides, use the selected target in client configuration and per-request overrides. Use it in curl Stripe-Version test headers, too. Replace bundled API versions shown in those examples with the selected target before copying or running them. For Java, Go, and .NET, select an SDK release that targets the selected API version instead of overriding the SDK’s fixed version. Preview targets need the matching beta SDK release in every language; see SDK versioning.

Understanding Stripe API Versioning

Stripe uses date-based API versions (e.g., 2026-08-26.dahlia, 2025-08-27.basil, 2024-12-18.acacia). Your account’s API version determines request/response behavior.

Starting with the 2024-09-30.acacia release, Stripe releases new API versions monthly with no breaking changes. Twice a year, a new major release (for example, Basil) starts with an API version containing breaking changes. You can safely upgrade to any monthly release without updating your code.
