⭐ Enhancements

Simpler ARS payout methods — bankAccountNumberType is no longer required, and neither is the bank: bankId on ARS Payout Methods, or bankName on inline ARS payout requests.

COP pay-ins via Bre-B — your Mural Accounts now always include a Bre-B key for receiving COP, alongside PSE. This was available by request before, now it is automatically provisioned.

New document types supported for the businessSourceOfFundsDocuments attestation — you can now provide INVESTMENT_COMMITMENT or UBO_SOURCE_OF_FUNDS document types when uploading source of funds documentation for your organizations. This is helpful for new businesses that may not have a bank account yet.
Associated Persons are now validated before submission — Their government IDs, proof of address and residential addresses go through the same validations as the rest of a compliance review, so problems show up before submission instead of coming back as an RFI. See Responding to RFIs.
New RFI attestation types — Our compliance team can now request two new attestation types in an RFI: supplementalDocument (one or more documents) and supplementalInfo (a written answer). Each request lists what we need, and either type can be asked of the organization or of one of its UBOs or control persons. If your integration answers RFIs over the API, update it to handle both types. See Responding to RFIs.

Simulated payout failures refund like production — a failed simulated payout moves to refundInProgress, then refunded. See Simulated Payments.

Removed decimal noise from certain API-based Payout responses — a withdrawal priced without a quote now returns its amount to (decimal) cents, where in certain cases would return more than two decimal places.

Payin fee percentages are exact — the payin and developer fee percentages no longer carry floating point noise from imprecise calculations.

RFI status webhooks no longer miss flagged submissions. Before this fix, an RFI could look stuck while validating because no status change was sent. See Event Types.
