Illustrative entry
This entry is part of an illustrative changelog. Paycux is in private beta and has not shipped this as a dated release; “live in staging and production” is not a measured claim. Real releases will be listed with their actual date and release identity.
This came out of support threads where the same question kept arriving in slightly different shapes.
Existing integrations keep working unchanged. The behaviour is additive, so you can adopt it when it suits you rather than on our schedule.
