Changelog

Stash Pay: Two updates to the Stash Pay checkout experience.

• Bonus rewards are now grouped into a single row in the Stash Pay V2 checkout flow for a cleaner presentation.
• Resolved an issue where Apple Pay and Google Pay buttons could appear disabled on initial page load.

Webshop: A bug fix for currency resolution in the Convert API.

Three updates to webhook events shipped this week.

Upgrading or downgrading a subscription mid-cycle now generates a prorated invoice automatically. The new behavior applies to all plans created after this date.

• Invoice line items now include proration: true when applicable.
• No migration required for existing subscriptions.

See the updated Subscriptions integration guide for details.

You can now customize the retry policy for individual webhook endpoints from Stash Studio. Previously, all endpoints used a fixed exponential backoff over 24 hours.

• Choose between standard (24h), aggressive (72h with more attempts), or off.
• Per-endpoint dead-letter visibility in the Studio logs view.

Learn more in the retries documentation.

We've expanded our edge presence to São Paulo, cutting checkout latency for South American players by an average of 180ms. No action required — traffic routes automatically.
