Changelog

User-facing changes to the Merchant API and docs.

2026-05-28

Payment intent examples use the public MY_FPX method code and include the required customer object.
Payout cancellation examples show the immediate 202 response before the asynchronous terminal cancellation state.
Webhook docs link directly to the generated GET /webhook_events API reference.

New entries land here the moment a public change ships.
