PG 1.27.0

These are the changes we’ll be releasing on acceptance on 08-10-2025

Changelog:
Features:
• Our checkout now has data-testid values for each component it uses. This allows automated tests to run against these IDs instead of having to rely on specific names/values.
• Added an endpoint to get the refunds created through using the checkout refunds endpoint. This functionality was previously possible by implementing the payment method specific endpoints but is now also available through the checkout endpoints.
• The REFUND_STATUS event request body now also contains the refundID
• (internal) We can now get refunds for a checkout using checkout-api
• (internal) We can now process transaction status updates in our checkout-api project.
Improvements:
• (internal) Update packages.
• (internal) Improved the data retention job to speed up some queries
• (internal) Instead of returning the “UNKNOWN” status which is undocumented we now return a 500 internal server error.
• (internal) Removed code to interact with the old hosted checkout. All merchants have been migrated to our own hosted checkout.
• (internal) Configured the creditcard psp URLs in common-api and checkout-ui to enable the creditcard transactions using our new psp on production.
• (internal) refactored IN3 docs, this change won’t be live until every payment method doc has been refactored.
• VAT amounts for items (aka order lines) are now the total vat amount of the order line, no longer per item. This allows for fewer currency/amount calculations to happen in the Klarna process.
• Removed an old debug endpoint (trigger-webhooks) which has not worked or been used for years
Fixes:
•
