Provide a 1 to 4 character ISO 20022 ExternalPurpose code to describe the nature of the transaction. We added the full list of supported purpose codes to the payment rules page. #### Link to payment rules: [#link-to-payment-rules] * [Acme CIMB Singapore Payments (API)](/guides/cimb-api-payments) *** ## Jul 21, 2026 [#jul-21-2026] ### Report Files API [#report-files-api] We added the New Report Files API.

It now names every currency with no minor unit (0 decimal places) and every currency with 3 decimal places. We also clarified that the number of decimal places follows the ISO 4217 scale, not the smallest physical coin or note (for example, TWD uses 2 decimal places). #### Affected pages: [#affected-pages] * [Minor Units Format](/guides/minor-units-format) *** ## Jul 15, 2026 [#jul-15-2026] ### CIMB Singapore TT Payment Rules (API) [#cimb-singapore-tt-payment-rules-api] We added payment rules for the TT payment type to [Acme CIMB Singapore Payments (API)](/guides/cimb-api-payments) via [Acme single payments](/reference/post-payments).
